I started noticing this about 2 months ago but cannot define an event that would cause the change.
If I have an activity created in Outlook or CRM that is set to sync (I sync 99% of my activities with CRM), if I move that activity due date in Outlook, there is a good chance (though not seemingly 100%) that the task will move in Outlook just fine but CRM will display that task with no start or due dates.
In Outlook, the taks will still be properly linked to the correct CRM entity and have the new due date -none of the problems in the CRM view.
While this is fine for my personal task management, this could be a nightmare as I encourage my team to use CRM activities more heavily.
Anyone have any ideas? No amount of searches has given me a clue. I'm running CRM Rollup 6, Outlook 2010 with the most recent connector (same problem existed on rollup 2). I've tested syncing to two different machines -same result. No other devices are syncing (I've disabled all mobile task syncing to troubleshoot). Web-based Outlook reflects the same task information as in the application -dates are correct.
No fun.
