Mailbox Archiving State = 3
Can someone offer me a summary of what the status of 'Mailbox Archiving State = 3' actual means and it's implications?
We have an EV10 environment which was initially configured on Exch2007 but this was upgraded to Echange 2010 before user mailboxes were enabled. Journalling had been switched on but then the task stopped so essentially not really in production at all. Having brought the Exchange 2010 environment into EV a two node active active DAG I'm getting a lot of 'mapi session' ('Unable to get exclusive access to the MAP thread pool' and 'Could not get a mapi session from the session pool' etc) errors and ran the SQL commands to look at the Mailbox Archiving State and it retruned several mailboxes two of which were the system mailboxes (1 from each DAG node).
I was just interested to understand if this may be the cause of the MAPI errors and if it's just simply a case of recreating the system mailboxes - or if I should be taking different actions. Or perhaps this would be a blind avenue for me....
I have Outlook 2007 Sp2 with the correct hotfix installed to bring the threads from 32 to 100 and I have 6 runnning tasks all with the default 5 connections. One other things I'm unsure of is that I have a lot of Vaultmbxagent profiles in Outlook on the EV server. About 25 for DAG1 but only 12 for DAG2.... is this normal and why does one DAG have twice the amount of the other DAG?
Thanks in advance for any clarification
