This thread has not had any responses to it for a while, but since the migration is almost finished for the outlook.com users, I need assistance. I have created a new outlook.com account that is on the new servers (Outlook Mail at the top). My email for work is handled by a local company and I retrieve emails via IMAP. I have the imap account set up and working fine. My outlook.com account was added by entering the simple settings and allowing the automatic configuration in outlook 2013. My IMAP account is set as the default email account and my outlook.com account is set as my default data file. I have migrated all my contacts and calendar items to the outlook.com account and appears to be syncing just fine. Here is my dilemma:
When I create an appointment from a received email in my IMAP account, it added it to the (this computer only) calendar that was apparently associated with the IMAP account. I followed your instructions for removing them from the folder list. This worked fine, but now when I try to add an appointment from and email or accept an invitation, I get the message that the calendar could not be found. I noticed that my outlook.com account is an .ost file. I thought the new server accounts were going to be exchange data files? Anyways, can you help me resolve this issue of not getting all my invites and new meetings to the outlook.com calendar.
Thanks
Pat.
