Lately I could gather some new information and I would like to share it with you.
QMMEX connection problems Part I, was about the circumstances that may hinder a successful synchronization of Exchange mailboxes with Quest Migration Manager for Exchange.
Part II covers connection problems with Mail Source Agent (MSA) due to deactivated email protocols.

The Mail Source Agent (MSA) of Quest Migration Manager for Exchange cannot connect to the source mailbox because the MAPI protocol is deactivated.
The following error message appears in EMWMSA.LOG:
This is a problem which can be prevented in advance. To ensure a connection of the Mail Source Agent, just query the email-protocols via PowerShell.
And here is the PowerShell script to do that.
