Enterprise Vault and Exchange 2007/2010
I have a customer in the process of migrating from Exchange 2007 to Exchange 2010. I have all mailbox servers set up as targets on EV. In addition, I have 2 EV servers.
Currently, the Exchange 2010 servers are being archived successfully. However, I'm not so sure about the Exchange 2007 server. The MSMQs related to the archiving task for the Exchange 2007 server have messages piling up, and they're not moving; ie they appear to be stuck. They've been in the same state since about 7 pm last night (sunday, 4/7/2013). The queues that have messages backing up are: a1, a2, a3, a5, a6, a7, and the admin queue. Since the a3 and a5 queues have messages backed up, I'm reluctant to just clear the queues and try again. All mailboxes on the Exchange 2007 server have been provisioned and have successfully archived prior to the addition of Exchange 2010.
A little more background:
On one EV server, I have the the archiving task for the Exchange 2010 servers, along with Outlook 2010 for MAPI compatibiltiy, and an EV system account
On the other EV server, I have the archving task for the Exchange 2007 server, along with Outlook 2003 for MAPI compatibility and a different EV system account. This task was previously on the same server as the Outlook 2010 mailbox archiving tasks, but it wasn't working. I separated it out to another EV server for a more granular approach plus I was concerned about MAPI compatibility for Exchange 2007/2010 with EV, so with this configuration I can have the 2 different versions of Outlook.
The bottom line, though, is how do I get the previously mentioned queues to empty, and ensure EV is processing properly for my Exchange 2007 mailbox server?
