Never mix personal and business – a sordid tale


I have an Office 365 Home/Family subscription. Has worked reasonably well. Yesterday I made the fateful mistake of trying to join a Microsoft Teams organization (for a volunteer organization) and decided to use my personal email – the same email I also use for my Office 365 subscription. It seemed to work fine and outlook on my machine continued to work as expected.

Today I had to reboot and when I when into outlook – nothing would connect. I logged out, deleted the profile, etc – nothing. Just constantly hung – first checking secure and then unsecured connection for my organization. That was my first clue something might be wrong. Organization?

I went to the Windows 10 mail app – no problems. Went to the Android mail app – no problems. Went to the web to log in and –

“It looks like this email is used with more than one account from Microsoft. Which one do you want to use?”

“Work or school account. Created by your IT department” or “Personal account”

I began to suspect that when the outlook client was attempting to connect it was running into the exact same question and didn’t know what to do.

I left the Team group. Nothing. I did some searching and discovered that by going to and going to my account settings I could see all of the organizations I belonged to. I found that volunteer organization and choose “Leave”. Closed everything.

Logged back in (even under incognito) and I still get the same prompt – it still thinks i have an email associated with another microsoft account. But now even by going to I no longer even see that organization – it’s gone but my email is still hijacked.

And now my Outlook desktop client is completely useless. Completely. Utterly.

No idea what to do now. Any suggestions?

    Changes in Teams can take up to 24-48 hours.

    Run an online repair of your Office installation.

    I have one account that is actually an organization account tied into a personal account version (so similar to yours, only backwards). I stopped using the "personal" version, but it is still there and will show up at times. I'll have to look and see if I can login to it and cancel it.

    Is your Outlook using "Modern Authentication"? I've run into this issue when not using modern authentication. Try this and see if it helps. Run Regedit and go to:


    (substitute "-" with backslash, the editor won't let me type a backslash)

    The 16.0 may change depending on your version of Office.

    On the right-pane right-click and choose New DWORD Value 32 bit

    For the parameter name enter: EnableADAL

    For the value enter: 1

    Close regedit, close outlook and try creating a new profile. If you were not using modern authentication it should now use it and ask if it is a work or school account and all that crap.

    Hope it helps.

    You may have run into the Outlook outage from a few days ago. Maybe that is causing a lingering issue for you somehow.

    It is possible to use the same email address for both "work and school" (365 Commercial/Education, Azure AD, etc.) AND "personal" (Xbox, Hotmail/ accounts.
