SBS 2003 exchange store failing offline

Posted on 2014-09-18
Last Modified: 2014-09-22
I have an SBS 2003 machine with built-in exchange installed.

All worked fine for years, but now the store is constantly going offline. To get it back up, I need to manually set it online.

Any ideas what to do? I tried repairing and defragmenting database, but that didn't help.

i would look at the event logs and find out why
my first guess is that it's hitting the storage limit and dismounting

take a look at this article
if you have SP2 installed you can increase it

What is the actual size of the database? Maybe it grew above the maximum limit set by MS. What Exchange service pack is installed?

OK, guys - this is a start. Can't connect to the machine now (weird problem with TeamViewer), but will go there tomorrow, and report back!

OK, so my DB is 19GB large.

However, this being an SBS - I can't find the registry key to change DB max size! (I hate SBS. It lacks many tools of the actual software packages.)

If the value does not exist just create it...
SBS is not that bad - in fact Exchange in SBS is not missing anything and is a full product :).
Also please not that you have to be on SP2 for this to work.
