For right now, we're using the mailbox summary logging for our EmailXtract jobs. I've noticed that for some users - not all - their mailbox name will show up twice.

The first time, it will say:
Mailbox: User A
Then the second one will say:
Mailbox: User A CodePage 1250.

It doesn't appear that there is a problem with the jobs, I'm mostly curious as to what this extra entry means. When it appears, items are archived under it, but it doesn't seem to show up on everyone. Should this be a concern, or could anyone explain what this is?

Thanks!
