Exchange 2000 .ifs files and 16GB IS limitation
I ran into a problem with a customer yesterday where they actually hit the 16GB limit (I think) in Exhange 2000. I had a couple of questions about this, mostly so I'm better armed for next time.
First, I have temporarily resolved this issue by using the registry fix that increases the temp size from 16GB to 17GB. The initial symptom was that the IS wouldn't mount properly. It would mount, but then immediately dismount as soon as someone tried to access it. Now that the limit is up to 17GB it mounts and users can get in.
But I think part of the reason I missed this is that I was only keeping an eye on the size of the priv1.edb file in the MDBDATA directory. Yesterday it was a little over 12GB, which didn't seem close enough to be a real concern. But when it crashed I began to wonder if the actual size of the store is the priv1.edb + priv1.stm. Because the priv1.stm file is a little over 4GB the two together would explain exceeding the 16GB limit. Can anyone confirm whether this is correct? Does the limit refer to the two together?
Also, as soon as the IS crashed the server started populating my MDBDATA directory with "IFS Files" ending in .ifs (for example, "FB7-8836B820-2E9F739.IFS"
Thanks,

Now I get the fun part of explaining to users that they can't all have 1.6GB mailboxes. They fought hard against my imposing limits. Now I get to tell them either live with the limits or shell out $$$ to go to 2003.
That'll go over well.
