Why are my exports failing?? - 3.Jan.2017 11:12:49 AM

First and foremost, I'd like to advise all of you that I'm a pretty inexperienced exchange admin and was promoted to this position from a help desk lead position maybe 6 months ago. So please ignore any of my incorrect terminology- I�m still learning how to speak-exchange (lol)

Anyhow- the company I support has about 50k employees, and one of my tasks is to do legal pulls on a weekly bases. 99% of the time these pulls go through with no problem. That additional 1% of the time, though, the PST export fails at a random point in the export.

When a mailbox export fails, the only solution we currently have is to move the mailbox to a different database and try the export again. In my limited experience, that has worked 100% of the time thus far. Other exports to the same database complete fine. If I move the mailbox to a different DB then move it back to the original DB, it also works fine- but only AFTER the move. While we do have a baditemlimit set for the exports, we do not have it enabled for the DB moves

The issue isn�t specific to large or small mailboxes, which databases the exports originate from, or any other criteria that we can identify.

Also, I�ve noticed that when this happens, the server on which we are saving these PSTs will lock the PST file of the failed export and show it as opened until I remote into the server and manually close the file�s open session. This doesn�t happen with exports that complete properly.

Has anyone seen this before??
