When the LEDN of the user has a single quote then MTA fails with this error.

CSA can work fine and can process such a mailbox.

This happens only when the QMM Exch hotfix from May 2011 has been installed

Renaming the account and then deleting the target mailbox and purging it and then performing a full AD resync and recreating the target mailbox (so the target LEDN doesn't contain the quote) will help.

Alternatively a non-updated agent can be used. Since the update cannot be uninstalled one can try and uninstall the agent and then install the MTA locally and not update this agent (and the host).

This affects only QMM 8.7 installations where the MTA has been updated with the QMM Exch hotfix from May 2011
