Enterprise Vault 9.0.5 Event ID 2267

Hi,

Full text of the Event ID is:

Failed to make the message titled: "Message Subject" Archive Pending for Mailbox "Mailbox DN" 

I have 1,000 of these from 8 (of 5,000) specific users, we archive 1,000 messages per archive run.

Previously I have seen these relate to mailbox quota limits in Exchange but for these 8 mailboxes I cannot find any reason for it.

Read http://www.symantec.com/business/support/index?page=content&id=TECH51036, can't see it personally and odd how it errors for the 1,000 eligible messages for these specific mailboxes.

Any suggestions or suggestions to troubleshoot further?

Thanks
