I have been getting lots of Event ID 27 entries in my Application log when i run Outlook. It says: When I open an entry, it says: Calendar Folder Property is Missing.
I discovered that when I remove the data file "Archive.pst" from my Outlook account, NO Event ID 27 entries appear in the Application log.
When I add the data file "Archive.pst" back to my Outlook account, then Event ID 27 entries start accumulating again.
I did a SCANPST of my archive file. It contained errors, but the scan repaired them all. When I opened Outlook the Event ID 27 entries appear again in the Application log.
If you have a solution, please pass it this way. Thank you for taking the time to help me.
