Our customer has one mailbox with several folders with DoNotArchive Flags.
This is an old one mailbox which is re-activated. Now it's not allowed to use Full-Client to unmark the folders.
Further it's not allowed to use the Regkey ClearDoNotArchive on EV-Server.
We try to zap the mailbox, but this didn't help us. The markers always there.
Solved! Go to Solution.
The DoNotArchive flag is stored in a hidden filter message in the folder's associated contents table. You can get at this using MFCMAPI.
Open the mailbox store, navigate to the folder in question, right-click the folder and "view associated contents table..."
Find the message with message class "IPM.EnterpriseVault.Filter.SiteName" and delete it. DoNotArchive flag cleared.
Repeat for each folder that's giving you the trouble. (If you have a ton of folders with the problem, it is possible to script the deletion using EWS.)
