Sumit Gupta: > Decompress Exchange folder in Program files.

Is that the only way? I compressed for a reason that being lack of free space on the drive. Does the above error listing provide ideas for alternative solutions? If not, I try decompressing.

Sumit Gupta: I don't have a 'Program Files \ Exchange' folder. I have 'Program Files \ Microsoft \ Exchange Server'. Is that the one you mean?

I also tried restart Exchange services. I've done this before successfully, but now I get the following errors:

Generally speaking, compressing the C: drive is a best practices no-no. Mostly due to the performance issues this causes. If you have a storage issue, resolve it correctly not with a band aid.

Uncompress C:

Gary Coltharp: > compressing the C: drive is a best practices no-no. ... If you have a storage issue, resolve it correctly not with a band aid.

The problem here is that SBS2008 is running on an HP Proliant with only 500GB of total disk space. That 500GB is in the form of a RAID1 array in an HP Smart Array. Unfortunately, it cannot be expanded unless we purchase a P400 Battery Backed Write Cache Controller -- foolishly not purchased with the Proliant -- along with larger specialty drives.  The cost to do this is more than replacing the whole server. Plus, SBS 2008 is obsolescent and the HP Proliant has other issues (e.g. cannot boot with USB drive connected). I am in the process of replacing this server, so a Band-Aid is just what we need for a few months!

Sumit Gupta: > Hi, yes i mean Microsoft/exchange folder.

I assumed that's what you meant and uncompressed this folder last night and Exchange started working again! Whew! Just in time for work this morning.

> Compressing exchange folder is never recommended.

Apparently, but it would be nice if Microsoft either warned about that, or bypassed compression of Exchange. Perhaps they do in some secret MCSA/MCSE  knowledge base, but searching for hours on the Internet turned up NOTHING related to this issue. Maybe I'm a bad surfer.

Thanks. This suggestion saved my life!
