I have an exchange server that is replicated off site for DR and have recently noticed that it is creating more than I would expect of replication data. The database size is just under 15GB with about 10 mailboxes, so relatively small. I am seeing a large amount of .tmp files being created then deleted in the windows\temp folder and think this is what is causing my high replication data. These files have random GUIDs as file names and can vary in size. I quick stop of the information store stops these files from being created so it is obviously exchange doing this.
I have tried searching the web for information on the creation of these files but can’t seem to find much. Does anyone here know if this is normal or if it can be stopped? I have access to a number of other SBS servers with Exchange 2003 on and don’t see these files being created on them.
Last thing to mention is that there are a couple of files are being created/deleted every second.
