Hello.. Our Exchange database was getting large, so I decide to do an offline defrag to recover some space. The defrag would get about 20% done and error out with a jet database issue. I ran the eseutil with the /k switch and found lots of checksum errors.. Still not able to defrag the database, and it rapidly approaching the 16 GB limit, I became desparate... I was able to do a defrag of the EDB file only by using the -i switch...(excluse the STM file from defrag) That has gained me quite a bit of space. The problem still exists... I still have issues with the STM file.. Anyone out there heard of this? - W Abucewicz
