Issue with group calendars deleting entries
We noticed that our group calendar entries have been erased (not sure how) for one of our Groups. Has anyone seen this with any other group calendars? How do we find where these entries have gone?
Joseph Reynoso We have had this happen to our group OOO calendar several times. We've called support a few times and haven't been able to recover the lost past/future events or get it to stop happening. It happend again this week. We are now looking at other calendaring options but I don't love that, so if you get anywhere with this o365 issue, I would love to hear about it from you!
- What do you mean by "one of our Groups"? By the way, I'm afraid you won't have an easy way to get this information...I have just reviewed if the Compliance & Security Center provides a way to get this information by means of the Audit Log Search, but unfortunately that's not the case
We use an Office 365 group to manage time off and other items. Last week, someone noticed that all past calendar events were no longer in the calendar. We will follow up with the powershell command to see if we can capture what happened. We haven't asked around to see if others are experiencing the same issue.
Did you apply a retention policy to the group by any chance? A retention policy will remove items after they are a certain age...
There is no way to enable auditing on the underlying mailbox that I know of, thus we are unable to capture item-level events for Groups. TonyRedmond might know better...
Are the deleted calendar items in the Recoverable Items folder or Deleted Items folder? You can run Get-MailboxFolderStatistics against the group mailbox to see how many items are in these folders and if it seems that there might be some there, you can run a content search against the mailbox to find the items and export them to a PST. You then have the items - but as mailbox auditing is not supported for a group mailbox, you can't find out who removed them.
