Tasks Sync to Exchange Server with Wrong Date

[shanek1]

Problem:

The issue I am having is syncing tasks between my Sprint Mogul (3.56 ROM/WM 6.1) and Exchange Server 2007. If I enter a new start/end date on an existing task from the phone, it will sometimes sync to the Exchange server a day off and sometimes up to a week off while remaining correct on the phone. This does not occur when entering a new task with a start and due date. When editing the task via Outlook 2007 or the Exchange web client the tasks sync fine to both the phone and Exchange server. It appears the issue only occurs with task as contacts, calendar and email entries sync fine both directions. I can edit the task notes or subject fields from the phone and these will sync fine with the Exchange server.


Attempts to correct:

I have deleted all the tasks (only around 60) and manually recreated them.


Unchecked sync tasks and rechecked tasks to sync from both the phone and WMDC.


Verified the timezone is the same on both the phone and the Exchange server.


Performed a hard reset on the phone.


Deleted/recreated the sync partnership.



This seems to have started after migrating from Exchange 2003 with 1and1.com to Exchange 2007 with Sherweb Exchange hosting.



I am at a loss on what could be causing this or what else to try. I am certainly open to suggestions.
