Can't remove old company's certificate on Authenticator so can't use new company's email

I can't get into my Outlook account because I can't get my delete my old employer's certificate from Authenticator on my iPhone. I've found the setting that allows for deleting account certificates, but when I go through the deletion process, I still end up with the old company account attached. Since I don't work for that company (and haven't for over a year), I can't go to their portal to delete the account.

My new employer's IT doesn't know how to solve this problem without wiping my phone, which I don't want to do, especially since I don't know how that will impact my personal Office 365 account. Is there a way to fix this without wiping my phone? And if I were to wipe it, how would I avoid the old certificate from getting loaded from the backup?

    Ok, sounds like intune or some similar device management tools software is being used. The managment tools admins will need to get involved to solve this one. This is not an authenticator problem. Unenrolling may be a possibility.

    I had something similar to this for my github account with my mac. I wasn't able to connect my work github account to vs code because my mac saved my personal login credentials to keychain. I had to delete those credentials in keychain before it would switch accounts.

    Maybe check and see if something similar is going on with your keychain access on your iphone. If you find your old credentials and delete them, then your phone should automatically save your new credentials when you sign in.

    I get an error saying I have to delete the old credentials.

    Sounds like you'll need to remove the account from the mobile phone settings. To do this on my android phone the steps would be Settings\Passwords & accounts
