How can you clean up office365 group mailbox

Question

I wanted to clean up a group mailbox which is enabled with send as rights. The mailbox is almost full and there is no easy method to remove all old emails from this group mailbox.

You can use retention policies, or some EWS-based script.

Thanks Vasil. Are there and documentation available for references.

It's covered in the Retention policies documentation:&nbsp;https://docs.microsoft.com/en-us/office365/securitycompliance/retention-policies

VasilMichev&nbsp;But that refers back to individual maibox. How can this be applied on Group? I dont see this under Recipients-&gt;Mailbozes section in Exchange admin center.

There's an entire section in the article detailing Group mailboxes, read it:&nbsp;https://docs.microsoft.com/en-us/office365/securitycompliance/retention-policies#office-365-groups-locations

Exchange retention policies do not apply to Groups, you cannot use the EAC for that.
