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?
