    Did you receive the error "One or more parameter values are not valid" ?

    Most likely your mailbox or tasks on a Microsoft Exchange server have been corrupted.

    A way to fix this without losing data is:

    1. Open your Task folder
    2. Set it to Simple View
    3. On the Actions menu click Save Task Order
    If this doesn't work then you should contact your Microsoft Exchange administrator so they can recreate your mailbox.
