I am trying to move messages from a rather large mailbox to an archive mailbox. However I run into errors all the time.

the command I am executing is

Export-Mailbox -Identity MAILBOX_FROM -TargetMailbox  ARCHIVE -TargetFolder ARCHIVE_FOLDER  -StartDate 2009-02-01 -EndDate 2009-02-28 -DeleteContent -Confirm:$false

I can copy/move some messages, but run into frequent "an unknown error has occurred" (statuscode -1056749164)

I run the console as administrative user, and all permissions are set right, as far as I can tell. I've restricted the start and end dates in case the number of messages moved/deleted should create problems.

Anything I am missing in my setup? Corrupted messages? Over-limit message sizes?
