Just upgraded my Nexus 5 to Lollipop and have bumped into a serious issue with account management.
I have my Google account registered to a non-gmail domain, and use Exchange Online to host it. Up to Kit-kat, this presented no particular issue: I would log in to Google’s services using my Google account and then add a corporate account to handle email.
Lollipop prevents me from doing so however: whenever I try to add the corporate account I get an error message saying the account I’m trying to create is a duplicate (this happens at the very first screen, when the only available field is the account’s email address - which of course is going to be the same).
Has somebody found a way around this? If not, what is the best way to submit a bug report, since the Gmail App is not part of AOSP?
