Outlook 2007 Calendar Gremlins

Yes, I said Gremlins, because thus far I have not been able to recreate the issue.  Here's the setup, and pray for us as we have inhereted a mess.

1 Server (SBS2003) Running Exchange
6 Clients (all WinXP Pro) w/ Outlook 2007

They are using a hosted POP3 Email server, but connect to exchange only to open a single shared calendar...this is why we are now invloved...

The issue at hand relates specifically to appointments in the calendar.  The calendar is assigned to User1's profile, but all the other users add or change appointments on it to keep him informed.

So, user3 changes something in the appointment like time, date or location.  A week or two goes by and somewhere in that time frame the appointment "reverts" to it's previous setting.  There are two laptops in the office, but they never leave the office, nor are there any PDAs.  They access this one calendar strictly through Outlook.

Only one user (user3) has been reporting the problem, as she notices most often from the items she adjusts.

I have disabled all third party add-ons on her system, and even re-installed outlook, yet the gremlins still continue to attack at random and in an undefined pattern.

It seems as if the calendar is being over-written from some where, or perhaps being recovered from a previous state...automatically.

    How are these users accessing this Calendar.
    By Opening a shared calendar or by having the actual mailbox added as and additional mailbox?

    Is User1's profile set-up to use Cached Exchange Mode?

    Users access User1's calendar as a Shared Calendar.
    All Users are using Cached Exchange Mode.

    I have a feeling that this may be the cause of your problem.

    Turn Off Cached Exhcange Mode and Test.
