I just got my Lumia 920 and stumbled upon a weird problem. I have a Google-account (with calendar sync) and a custom Imap-account (company's emails). They both have the same email address as user account. Whenever I try to add one of them after another, the phone tells me that "the email address is already in use".

Has anyone tried to create/sign in to accounts for different services, with the same username? I don't understand why WP8 doesn't let me do this, since they are two different services, but of course both of them can share the same use name.

Also my Google-account is unable to share the calendar with private iCal-link (has to something about a paid service for google tools etc.) Should I just create a new Google-account and migrate all my calendar markings there?
