this is interesting, i couldn't find a simple way to delete search-folders from "Discovery Search Mailbox". The search-folders were created when I ran "Search-Mailbox" command on any user-mailbox to do some search.
Some one said to use ECP and use mail-control, but I am on Exchange 2013 and I have EAC, there is no mail-control.
the other way is to delete and re-create the default discovery mailbox in Exchange. I do not want to delete the whole discovery mailbox to just remove a folder which was created by search.
i cannot delete it in Outlook as it give me permission denied message. when checking permission, it shows only "default" and "anonymous" with "None" permission level. i could add my name though, but it only applies to that folder only, the child folders not inherited, and even after giving me permission as owner, i am not able to delete (which may be ok because child folders in the tree does not have my name as owner). i dont see the Discovery Search Mailbox in OWA.
I am on Exchange 2013. On server I have EAC (Exchange Admin Center) but not ECP. On EAC i do not see mail control feature. This should have been a simple task or command to just remove search-recovery folder from "Discovery Search Mailbox". I have four folders in that mailbox for the same search query, each time a different target folder. One of them was created from "in-place eDiscovery & hold" menu in EAC. I can delete that saved-search under "in-place eDiscovery & hold" and that will probably delete the folder (I am not sure about this part), but the other three folders were created by search-mailbox command (similar search queries on same user-mailbox) and using different target folder in "Discovery Search Mailbox", how do I remove those? There should be some powershell commands to remove those folder. I am not sticky to powershell commands only, as long as the folders are removed and mailbox is cleaned-up.
I need help. How do I make it work?
