I dismounted a database to try and fix the backup. It's not in the list of databases anymore, and I can't figure out how to mount it again. Googling does not help. Does anyone have any suggestions?
Edit for details:
Exchange 2010. I dismounted it by selecting it in "Database Management" Under organisation configuration. If I remember correctly it should then still show up, but just show as "dismounted" - But it's not there anymore. The only database that remains is the Public Folder Database.
