Archive Rentention policy removing calendar entries
Hi
I have just implemented a retention policy on our corporate mailboxes for the first time and it was set to archive emails over 6 months old to an 'In-Place' archive. There are no delete settings so the intention at the moment is to keep all emails over 6 months old in the archive.
Users have found that calendar entries older than 6 months are being removed. I didn't see this in the guidance so I just want to understand the relationship, is it possible to reinstate them. I have deleted them so they must be archived somewhere?

It is actually mentioned in the documentation, last bullet here: https://docs.microsoft.com/en-us/exchange/security-and-compliance/messaging-records-management/default-folders
As mentioned in that article, if you don't want the Default tag to apply to these folders, you will have to include a Calendar tag and set its properties to "disable retention".
Hi
Thanks that's my mistake. If the calendar entries are archived is it possible to get restore those items.

It's possible, but not in an automatic way unfortunately, as we don't have any "revert retention policy" type of functionality. Closest you can get is to use some EWS-based script that copies/moves items between the archive and the main mailbox, here's a sample one: https://code.msdn.microsoft.com/office/PowerShell-Merge-mailbox-e769c529
You can modify it to include just calendar items and just specific time range. Other than that, it's manually moving the items...
