We've been having a problem with out mail server and get the following error
Exchange store 'First Storage Group\Mailbox Store (servername)': The logical size of this database (the logical size equals the physical size of the .edb file and the .stm file minus the logical free space in each) is 75 GB. This database size has exceeded the size limit of 75 GB.
This database will be dismounted immediately.
It seems simple enough so we deleted some old accounts and set some size limits and last week did an offline defrag of the database. This morning we got the error again and I had restarted the Information Store service which seems to make it work for a day or so but the problem is I went into the Mailboxes in the Exchange system manager and added up all the mailboxes and it comes out to about 44G of data between all the users. So we're not even close to the 75G limit.
Has anyone else seen this happen before and know how to fix it?
