Event ID 9690

'{storage group name}Mailbox Store (Server name)': 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 {x} GB. This database size has exceeded the size limit of {x} GB.

Seen on Exchange 2003 (Including SBS 2003), Note you need to install Exchange 2003 Service Pack 2 before you can proceed. Basically you have exceeded the maximum allowed size of Database that Exchange allows, before SP2 this was limited to 16GB. (Note: That's Exchange 2003 Standard only!! there is NO Limit for Exchange 2003 enterprise). {source}

After SP2 you can increase the limit up to 75GB (Again we are only talking about Exchange 2003 Standard here).
