A mail-enabled public folder has disappeared overnight (and is still within the deletion retention period) and the 2 users who have access to it swear they haven't deleted it. They also checked everywhere in their Outlook folders to spot if it was accidentally moved.
Assuming it's been deleted anyway (what else?), I followed the 2 recovery options in this post without success:
- In Outlook 2010 (don't have 2013), I can't see the folder in the deleted items recovery wizard, although I have root access to the folder
- The `Get-PublicFolder –Identity “\NON_IPM_SUBTREE” –Recurse | FL
C:\pf2.txt` result list doesn't show the missing folder
Since that folder was receiving our company's firstname.lastname@example.org email, I tried recreating it to at least keep on getting messages, but I got the following message:
error domain.local/Microsoft Exchange System Objects/Contact 34753643 The proxy address "smtp:email@example.com" is already being used by the proxy addresses or LegacyExchangeDN of "domain.local/Microsoft Exchange System Objects/Contact". Please choose another proxy address.
Where is the folder hiding? What else can I do to recover it?
PS: I don;t know if it's relevant, but Exchange was migrated to 2013 last week with a few problems. That public folder though was working fine until yesterday, post migration. All the other public folders are ok.
