We found out the hard way that the standard Exchange 5.5 has a Information
store limit of 16GB, but the Enterprise Edition doesn't. Why my predecesor
didn't get the Enterprise Edition, I don't know! Here's my question. Our
Private Information store exceeded the 16GB limit and shut down. I was able
to do an offline defrag and get it running again, but the size still shows
up as over 16GB. I don't know how much longer it will stay up before
encountering the same problem. Is there any way I can reduce the size of
that information store? We had a user who has left the firm months ago and
we finally deleted her mailbox! Her mailbox alone was 1.3 GB! After
deleting her mailbox, we only regained 200MB of space!!!! What gives? Any
idea as to why I didn't get back the space? According to Event 1221 from
the Online defrag, I will only reclaim 1MB if I do another offline defrag.
I've deleted several other mailboxes of people who have left the firm, but
it doesn't even put a dent in the private information store's size. Please
help before my server goes down again!!
