Setup user on server running v 1.1 build 343. Phone does initial sync, then nothing sync's after. User is able to send email from phone. We have run gwchecks against account, no problems.

In the logs seeing entries like this:

Haven't seen an event for user for 3600 seconds -- forcing check

There are new emails, user gets hundreds a day.

We have deleted account off server and added back, with the same result.
Any suggestions?
