We are having a problem today where no user is getting email on there pda
(Treos or Window Mobile. Even the web client does not show new email.
We have restarted services already, but that has not helped. A reset on
a user did get the mail to sync once, but new email will not sync.

The only error in the log was from 7:45 AM which is when the nightly
maint runs. the error is: Mobile Server unable to deliver message to
Email Accelerator.
