Do any of you experience this? Usually it doesn't happen but I guess this past week I have been hearing it a lot, right now as I type I hear the teams call ringtone.

I did some research on it, apparently its more likely to happen if you have a persistent low frequency sound in the background or something like a fan/air conditioner etc. Was wondering if anyone else gets this issue, I guess easy way to deal with it is to listen to music or something. It's not like I am getting stressed or anything from work and that's causing it, I think because I am just so conditioned to hear that noise, and also even though I was in the office today plenty of people still leaving their desks and waiting for that teams ringtone to bring them back. Kind of insane how embedded Microsoft teams is into work culture nowadays.

First-contact safety tips saved our inboxes. Now, phishing scams are finding their way into Microsoft Teams chats, too.

Static warning banners telling you a sender is external or contacting you for the first time are no longer enough! 

So, Microsoft Teams is introducing AI-powered, context-aware phishing detection. ️This new detection technique can scan and flag suspicious external first-contact chats before you fall for them. 

What does it look for? 

Instead of just looking for malicious links, it analyzes full conversation context in 1:1 and group chats to flag impersonation, social engineering, and fake external pings. When it detects suspicious content, it displays a warning banner stating, “This message could be a phishing attempt.”  

If you see this warning, here’s what to do: 

• Confirmed phishing: Don’t engage. Block the sender and report the message as suspicious directly in Teams. 
• False alarm: Select More options → Report as not a concern on the flagged message. 

While reading this, you might wonder: does AI use these chats for training? Don't worry! Microsoft confirms that chat data is used strictly for security purposes and isn’t used to train AI models or for unrelated purposes.  

Availability & Rollout Schedule: 

• Timeline: The rollout is scheduled to begin in early November 2026 and will gradually expand worldwide through mid-December 2026.   
• Platforms: Teams Desktop, Web, and Mobile (with enhanced regional protection in China). 

Think before you click, verify before you trust, whether in your inbox or Teams chat!

Nevermind I figured it out, I needed to toggle the "Show message previews for chats and team names for channels" in the "Chats and Channels" setting.

Teams is stuck in "comfy" chat customization mode, with wider spacing, and will not change to "compact" when toggled. Changing the setting does not change the chat pane at all. This behavior is the same on the web version of Teams, as well as the Windows 11 desktop app. Previously, I had cleared the desktop app cache, and also uninstalled and reinstalled the app. I even re-imaged my computer and it's still present.

Edit for clarification: When I toggle this setting, the actual chat message do change style, but the chat side pane does not. I swear that I had my side pane more condensed weeks ago.

Error 53003 (AADSTS53003) in Teams just means a Conditional Access policy said no. The quickest way I've found to pin it down:

1. Ask the user for the **Correlation ID** and timestamp from "More details" on the error screen.

2. Entra admin center > Sign-in logs > filter by that Correlation ID.

3. Open the **Conditional Access** tab on the failed sign-in. The policy marked "Failure" is your culprit, and it shows which condition failed (device compliance, location, client app).

4. Use the **What If** tool to confirm before you change anything.

Most common causes I see: personal device not enrolled, personal VPN making the sign-in look foreign, or an old client. Please don't "fix" it by excluding the user from all policies; those exclusions tend to stay forever.

I wrote a full guide with user-side steps, related codes (53000, 53001, 53002, 53004) and a KQL query to see which policy blocks the most users: https://techyami.blogspot.com/2026/10/teams-error-code-53003.html

I'm receiving Microsoft one-time verification codes and password reset emails that I never requested. Should I be worried?

Hey everyone,

I'm getting multiple emails from the Microsoft account team containing one-time login verification codes and password reset notifications, even though I haven't requested any of them.

I've attached a screenshot showing the emails I've received. I'm concerned that someone might be trying to access my Microsoft account or reset my password without my permission.

A few questions for anyone who has experienced this:

- Is someone trying to log into my account, or could this be caused by something else?

- Does receiving these emails mean they already know my password?

- Could someone be trying to hack my account using my email address?

- What steps should I take to secure my account and check whether anyone has accessed it?

I'm not clicking any links in these emails or sharing the verification codes with anyone. I'd appreciate any advice, especially from people who have dealt with this before.

Thanks!

We migrated our PBX to Teams phone recently and most of it works absolutely fine.

However, for our central number that is routed to a group using the call queue feature, we would like to have the normal call progress tone instead of a waiting music (we are a small team and it feels more personal than being put on hold in a music queue).

I only found the workaround of using an audio file that contains the tone, but this already has the call going, which charges the caller (not sure if it would be even legal to do it because of this).

Is there some other way to pull this off or is that the only way?

Hi

We're using Jabra Evolve 2 40SE in our environment, some of our users complaining calls to their Teams phone number are automatically being answered. Especially calls to a CQ.

At first sight the problem seems to be solved by unplugging the headset and plugging it back in, but after a while the problem reoccurs.

We've updated the Teams app, cleared the cache and updated the firmware of the headset.

Is there anyone who's facing the same issues atm?

Regards

I have never in my life had so much trouble getting a phone number through teams, but KYC verification is making me want to go a different directly completely. I go through the verification. It gets rejected because my documentation isn't sufficient. Ok, fair, the document from Godaddy providing we own our domain was just the receipt email in PDF form.

And as a side note here, why the hell can't they just use DNS like everyone else does? Why is all this extra verification required???

Anyway, I log into Godaddy as my boss so I can get the "right" invoice, I go through Microsoft support, they take forever, then finally get back to me today only to tell me the domain verification request for ourcompanydomain.com was rejected because the domain was identified as a "matched public domain". What the hell does that mean? I can't find any information online about that phrase, at least none that made any sense to me, but I'm probably dropping Teams as an option for phone, even though we have Microsoft for everything else, because they're making this process absolutely miserable.

Has anyone heard that phrase before, or have any idea why we can't do something as simple as getting a phone number?

I noticed this option in my Teams desktop app in my test tenant. Are you seeing it in your tenant too?

Just got the “Communities is retiring soon” notice in Teams Free. To clarify, this is the personal/consumer version, not Teams for work or school. Microsoft’s announcement.

I’m in the Teams Free Insider programme, and the corresponding community has already disappeared. Not even a goodbye 😅

As apparently one of the dozen people still using consumer Teams... what do we reckon the future is for this somewhat forgotten product?

If your tenant has Microsoft 365 Copilot licenses, you’ll soon see meeting archive files generated by AI for Teams meetings. The files are stored in a SharePoint Embedded container, but they’re not intended for user consumption. Instead, AI tools like Copilot and the Facilitator agent will use meeting archive files to generate better responses to questions from meeting participants about what happened during meetings. It’s yet another file type to figure out how to govern.

Okay, this might be a really specific question, but I've been overthinking it LOL.

I have a habit of submitting my assignments, noticing something I want to fix, clicking "Undo turn in," making a small correction, and submitting again. Except I've done this an embarrassing number of times for the same assignment...

I'm not talking about document version history or whether they can manually dig through submission records. I just want to know if, when a teacher opens an assignment to grade it, there's some visible counter or indication that a student has submitted it like 15 times. Basically, does my teacher know I've been fighting for my life in the submission tab, or does he just see my latest submission?

Would especially appreciate an answer from teachers who've used Teams for assignments!

I facilitate a large Team (1400+) people. For the past 2-3 years, I've been using the "send personal invites" toggle to invite everyone to a monthly meeting. This week, that toggle has disappeared. My admin is not aware of a new update and we are working on submitting a ticket with Microsoft. Anyone else experience this or know what might be happening?

I've used this extension to successfully download meetings but I'm trying to download one now that's 3 hours long and I'm getting the error "Segment failed: HTTP 500". Does anyone know why? Is there limit to the meeting length that can be downloaded?

Hello everyone,

I saw a post in this sub regarding microphone problems in Microsoft Teams with the Yealink A10. We use this device at work as well, so I took one home and think I found a fix (I'll test it at work tomorrow to confirm).

The problem was that the microphone worked fine everywhere else (e.g., Discord or WhatsApp audio calls) but not in Microsoft Teams. Even the camera's speaker-tracking function worked correctly during testing.

The usual fixes didn't work: checking for software updates (it was already running the latest version) or even performing a factory reset.

After the second reset, I set it up in Device Mode from the selection screen instead of choosing Teams or Zoom.

Then I went into the Windows settings and applied the following:

System > Sound > Input

Click on Yealink and, under "Set as default audio device", set it to "Default for communications".

Then set the format to 2-channel, 16-bit, 32000 Hz (FM radio quality).

After that, try testing the microphone in the Windows sound settings (mine showed about 20% input volume). Then I tested it in Teams, and it worked perfectly.

(Windows setting names may be different, as English is not my first language.)

Hello,

Recently, the Microsoft Teams desktop app has started showing the message mentioned in the screenshot.

Additionally, my Teams status is not staying as Available. It automatically changes to Away/Offline, and even if I manually set it back to Available, it changes back to Away after some time even when screen is ON and while I work on other apps.

I’m also experiencing significant delays with messages and notifications in the Teams desktop app. I’m missing several messages because they are not being updated or received on time. Interestingly, the Teams mobile app receives the messages first, while the Windows desktop app takes much longer to update.

I’m using the latest Microsoft Teams app for work on a Windows 11 computer.

Teams version : 26260.1717.5229.7049

Please suggest

Thanks

I know there a countless headset recommendations but I need a wired one not wireless.

Must be:

Noise cancelling
USB-C
Stereo / duel eared over ear (not buds)
Boom mic which mutes

Research suggest the Evolve2 50 but does anyone have an alternative recommendation

We enrolled 375 xcover 7 devices via Intune as managed kiosk devices. For all users it is working fine expect for 1 user. When the user picks up the sound is given via the device speaker each time (default) . We enrolled a other device but the same happens: sound via speaker. Anybody has an Idea?

I know the general consensus is not to use Teams Desk Phones, but I'm curious why Yealink has the MP55 and the MP56 E2 when the MSRP is only $10 difference. Why would you choose one over the other? Which do you suppose will be supported longer?

So, this morning we had a Teams Event. We had it set for anyone within our organization and had put the Teams Events Page Link on our company homepage. However, when users went to the Event Join page the Join link did not work. We were able to share the direct join link and get people to join but has anyone seen this behavior before?

Hi everyone,

We're dealing with a very frustrating issue on a Remote Desktop Server and would appreciate any ideas or troubleshooting suggestions.

Environment:

• Single Windows RDS server (not part of an RDS cluster)
• Around 10 concurrent users
• Microsoft 365 Apps, Teams, Outlook
• Users have valid Microsoft 365 licenses
• Plenty of free disk space on the server
• Windows on the server is currently not activated
• Users log off properly at the end of each day

Symptoms: Almost every day, users receive sign-in prompts from either Teams or Outlook. The messages vary, but typically include things like:

• "Your IT department requires you to sign in again"
• Requests to reauthenticate their Microsoft 365 account
• Teams showing connection/sign-in errors
• Outlook unable to connect
• Teams messages not loading
• Authentication failures or credential-related prompts

The issue affects most users at some point, but there are a few specific users who experience it almost daily.

Some of these users also work with multiple mailboxes and Shared Mailboxes, although the issue is not limited to them.

What we've already tried:

• Completely rebuilding user profiles
• Deleting local user profiles entirely
• Reconnecting Microsoft 365 accounts
• Reinstalling Office on the server
• Running Teams profile repair scripts: .\Finance-Fix.ps1 .\Users-Fix.ps1
• Clearing Teams-related data
• Signing users out and back in
• Full server reboot

None of these actions provided a permanent solution.

Additional observations:

• The issue appears isolated to this specific RDS server.
• We have other environments that do not experience this behavior.
• Disk space does not appear to be a factor.
• Users perform a full logout at the end of the day, yet the problem returns repeatedly.

Has anyone seen a similar issue on a standalone RDS server? Are there known Microsoft 365, Teams, Outlook, Entra ID, or token-caching issues that commonly cause repeated reauthentication requests in RDS environments?

Any suggestions for logs, Event Viewer locations, registry settings, Office settings, or best practices for running Teams and Outlook on RDS would be greatly appreciated.

Thanks!

Did anyone else wake up this morning to half their Microsoft Teams room systems offline? Looks like a failed windows update caused it as using windows restore has resolved the issue on at least one system.

It's across multiple makes and models of computer, across multiple time zones, in multiple countries, with some resource accounts migrated to passwordless and some not. It's been a crazy morning for me. Anyone else?
