It’s been a while since I last saw an 0x80004005 error, last time it was because the AV software on the Exchange server had quarantined a log file, but this server was not running any third party AV. On closer inspection the problem was pretty obvious;

Unable to Mount Mailbox Drive Full

My ‘log-file’ partition was full, (I had something else doing diagnostic logging), once I tidied up the partition and freed up some space the database mounted without complaining.
