Why can I not login without my phone?!?!

I am currently on my work machine. I am logged into Edge, Teams, Outlook etc.

I have a stupid legacy personal account that for some reason Microsoft allows to have the same email as a business account.

I don't have my phone with me today, but the ONLY ways that I can verify require me to have a phone?!

Why can I not auth through my iPad (which is logged in with my 365 account) or on one of the apps on my Mac, or via Email or with my password being sufficient?!

Unpopular opinion: Office 365 signatures should never be standardized with one giant mail flow rule

0 Upvotes

Unpopular opinion: using one giant Exchange Online mail flow rule to standardize Office 365 signatures is asking for a mess. My reasoning is that one wrong scope can hit every mailbox, department exceptions get buried, and testing with one account tells you almost nothing.

We learned this after I added the signature rule for our 140 users and selected the whole tenant instead of the pilot group. For about 20 minutes, every external email had our sales banner, legal footer, and a giant blank space where the job title should be. A few clients replied asking if our emails had been hacked. I feel so embarrassed even typing that.

I get why admins like native Exchange rules, especially when budgets are tight, but for a growing company I think email signature software with groups, approvals, and a real pilot is safer. What is the strongest argument against that?

Outlook Web, Apple Mail, Outlook Windows and Outlook Android won’t allow me to send emails because my “storage is full”. Click on the storage and it shows there’s plenty of space.

Same with Onedrive for Mac, all iOS and OSX Excel and Onenote apps, which is what I mainly use.

OneDrive Web and OneDrive Windows are working. This has been going on since 15 days. Support has been terrible. Lots of tickets created. Lots of screenshots shared, a couple of Level 2 phone calls. Lots of tickets closed. Usually saying “call this other department” or “just try after 1 hour” after doing the regular close/logout/refresh cache stuff.

This is an issue on their end. No amount of browser or device changing will fix it.

Every time I delete a few hundred emails, the issue goes away. Until it comes back a few hours later. This time, it didn’t go away even after deleting almost a thousand emails. I am going to run out of stuff to delete.

I couldn’t even reply to the last ticket asking me for screenshots, so I had to use my gmail.

I am paid up till March 2028 but if this isn’t a wake up call to get my own NAS, I don’t know what is.

I even tweeted @ Microsofthelps on X but they’ve ignored it.

Any help?

Transfer Microsoft Authenticator to new phone

20 Upvotes

In the past Microsoft Authenticator had an option in Settings to backup to iCloud. That was a great feature because on new phone those accounts would re-appear. I'm getting a new phone and noticed that the option to backup to iCloud is no longer available in Microsoft Authenticator. How do I get those accounts onto the new phone?
