We've recently migrated to O365, and since we've been experiencing appointments missing from Outlook calendar for one of our shared calendars. (This calendar is not a public folder; thus, it has a few users who have editing rights to it).


Any advice on how to approach this issue?


Thank you in advance.

@Corombi923 Did you figure out what was happening in the end?  I have multiple users who are seeing this across all of their shared calendars.

 

Each time they go into the calendar they get a different set of appointments.

@Corombi923 I too am seeing this behavior on some of our shared mailboxes. Any idea what's happening?

Maybe "Cache shared mailboxes" option?

Anyone ever get an Answer from Microsoft on this one?
