A specific recipient policy was mistakenly applied to all mailboxes in our company. I have changed the recipient policy to the correct one. I now need to restore (from delete items) all messages that that were affected by that recipient policy.
These users have many subfolders and I don't want to open outlook and use "recover deleted items" on each folder.
How can I recover deleted messages from all folders in a given mailbox? Can I constrain it by date deleted?
Use the Search-Mailbox cmdlet to search for items deleted today, and copy them back.
NOTE: I haven't tested this yet, so please follow all three steps and make sure it acts as expected!
Perform a search on a Test Mailbox and review the output:
Get-Mailbox "Test Mailbox" | Search-Mailbox -SearchQuery 'modified:(today)' -SearchDumpsterOnly -EstimateResultOnly
Perform a search again on a Test Mailbox and verify that messages deleted today were moved back
Get-Mailbox "Test Mailbox" | Search-Mailbox -SearchQuery 'modified:(today)' -SearchDumpsterOnly
Perform the search on all mailboxes and emjoy!
Get-Mailbox | Search-Mailbox -SearchQuery 'modified:(today)' -SearchDumpsterOnly
I hope this helps :-)
