The email i try to delete is in my virtual vault only (and not in my mailbox).
When i delete it (click on the email then 'delete key') from its folder in the virtual vault, first the email goes in the deleted items of the virtual vault. So, i delete it from the deleted item (click on the email then 'delete key'). At this moment, the email seems deleted (can't find it anymore in the virtual vault). Then, i launch a sync of the virtual vault : the email come back in its original folder in the virtual vault.
User are allowed to delete in the 'site propertie' but the retention category is set to 'Prevent deletion of archived items in this category'. It is set this way because i don't want users to delete an archived item. But i want them to be alowed to 'clean' their virtual vault (delete old items from the virtual vault to have more space for new items).
It is not alowed to delete items through archive explorer.
