We are in the process of migrating our mailboxes to Office365. I have most mailboxes successfully exported using Outlook's export option (File > Open > Import > Export to a file). Most mailboxes have all the mail, contacts and calendars exported and imported without issues.
However I have 2 mailboxes for which the calendar entries are not exported. Meaning, when I open the PST file, the calendar tab is totally empty. NO entries at all. Thus after I perform the import, the new calendar is completely empty.
Details:
- using Outlook2010 to export and view the PST file
- connected to Exchange 2010 SP1
- issue occurs in both online and offline modes
One thing I notice that makes these 2 mailboxes different: they delegated full access for the calendar to another user... In the mailboxes that I am exporting, no other mailbox has granted access, so I just thought I should mention this.
Also, I raised a question on Office365 forums, but after troubleshooting, I narrowed it down to an issue with the export of the PST file.
Thanks.
