Exchange 2003 dismounts automatically

We have SBS 2003 with exchage2003 configured. Since last few days I am facing a problem, mailbox is automatically dismounts after 24-48 Hours. I think this problem is related to mailbox size limitation. How can we check the mailbox size limit in exchange 2003? & How can we increase the size of mailbox? After automatic dismounting if I remount it, then it mounts successfully without any error. If this problem is not related to mailbox size, please let me know the problem & how can I resolve this problem? Looking forward for your co-operation. Thanking You in Advace.

HI,

The mailbox store limit in Exchange 2003 standard edition was 16 GB. They bumped this up to 75 GB with the recent release of Service Pack 2 for Exchange 2003. If your store is too big, you can see this problem where the store will mount for awhile then dismount. You can see where the logs are stored in system manager by going to Properties on the “First Storage Group.” The transaction log is listed there and is typically, %DriveLetter%Program FilesExchsrvrmdbdata. The store location is found by going to Properties on the store that is dismounting, then clicking on the Database tab. If either hard drive is out of space (assuming the logs and store are on separate drives – a recommended practice) you can have this problem. If you are doing a backup, the logs are supposed to remove themselves, if not, you have to delete them periodically.

Hope this helps.
