After I have upgraded Groupwise to 8.0.0 and GMS to 3.0.1 I have encountered a rather funny issue.

My devices can sync, I can access the webpage to the service. No errors.

But, new mails, calendar, tasks etc. are not flowing into GMS.

In the log, User activity I get:

09-09-2009 12:20:57 <userid> Unexpected failure detected: NestedException

for a specific user when his device is syncing.
