I use exchange 2007 SP2, and experienced backup and online maintenance job conflict several times. Even after I separated backup job and maintenance job running in totally different time.
In event log I found after event 1221 said how many spaces have been released by maintenance job, at the end of the online maintenance time window, event 1100 occurs several times again in next hours, said how many folder has been deleted. It looks very odd because I think after online maintenance job finished there shouldn’t have any database cleanup action followed.
I have only one mail storage database and one public folder. I also find there is a maintenance overlap warning at the end of the online maintnenance job. How can I find out what bring another maintnenance job? any idea or instruction will be appreciated.
