So, an Update on this:
Two environments:
Customer A
Exchange 2010 SP1 U5, EV 9.0.1
Journaling is activated. Upon archiving the Journaling Mailbox, the dumpster (recoverable items) is NOT growing. The dumpster is deactivated for this mailbox and has never been activated.
Customer B (the one with the original reported problem):
Exchange 2010 SP1 U2, EV 10.0
Journaling is activated, dumpster was activated but has been deactivated. Upon archiving the journaling mailbox, the dumpster (recoverable items) is growing very large (1,7 TB at the moment).
Any idea why this is happening? We will have a call with microsoft why the dumpster is growing when its deactivated (but has been activated in the past), but why is it growing while archiving?
Do journaling and mailbox archiving differ?
We are still trying to figure out, what to do now. We have a call for the microsoft patch for our own environment active as we see large database grows as well. If the patch helps, we will implement this on customer side.
I am unsure if i should open a call with symantec for the dumpster issue as well.
