I’ve encountered an unusual problem with Outlook 365 when an Exchange/Activesync account is added.
From what I can tell the problem is partly down to the fact that I also have an Outlook.com account on the same profile added as the default Exchange account.
Adding the Outlook.com account appears to have caused changes within the profile that lead to me having new Microsoft Dialogs when adding or changing accounts from inside Outlook.
When I add an IMAP account now I get a simple dialog at the outset that asks for my Email address and then when I click connect asks for my password.
At the end of the process I get an error that Outlook was unable to create the data file. (although one is created) and asking me to cancel or try again.
If I try again, I get the same thing, in the meantime, I also end up with multiple ost accounts linked to my profile but not linked to an active account.
The ONLY way to get rid of the problem ost files is to delete the profile.
If I use the Control Panel->Mail (Outlook 32) way of adding mail as a workaround I can add the IMAP accounts, as this continues to use the old dialogs. However it is a pain.
Are you guys able to investigate this?
