MicrosoftMicrosoftWe have a purview retention policy applied to our Exchange online mailboxes for a set period of time to retain and then delete emails which I assume is standard in most companies? This policy applies to the main Exchange online mailbox and also the archive mailbox. Priority clean up is only supported for the Exchange online mailbox so we are unable to delete emails from user Archive mailboxes? How do other companies deal with this? TonyRedmond​ have you got any experience of this scenario? We get rights to deletion under UK GDPR and currently can't fulfil these.
I wonder if lack of support for the archive mailbox is associated with lack of Graph API support for archive mailboxes... CRUD support for archive mailboxes is supposed to be coming as part of the project to deprecate EWS. Perhaps we'll see some movement then.
I can't speak for the developers, but the logic as to why support for archive mailboxes is not present is that the intention is to remove information from view that is current rather than the long-term storage in the archive.
Thanks TonyRedmond​, so at the moment there isn't a technical solution to permanently delete emails from an Archive mailbox if we use Purview retention policies without first removing the retention policy and then deleting the data before re applying the policy? I assumed other companies would have the same requirement under UK GDPR?
There is a technical solution. Find the information using an eDiscovery case and then use the Graph API to purge the items found by the case. Of course, you'll have to remove the retention policy to allow the purge to proceed...
