Exchange 2003, Outlook 2007 User's calendar changed to other user all of a sudden

I have a setup with Windows Server 2003 R2 Standard and XP Desktop clients running Outlook 2007.

Today, a user who manages other users calendars (3 of them) and a company shared calendar lists another user's name for Calendar when you click on Calendar.  This other user's name she and another user get all email forwarded to them for this user since they have left the company (for over a year).  

But today, the user logins and email accont is theirs and email send's come from this user.  But when you open the calendar, it shows another user's Exchange account for Calendar..  When they sent out an invite it comes from this other user etc..

What could have cause this?  It was all working fine last week.  The only changes to the server were applying some pending (15 important) Windows updates over the weekend (from the last month or so).  

Any ideas what to look at and how to fix?

I can't flow all the users. Give them names and restate the problem.

Server: Microsfot Windows Server 2003 R2 Standard.

All Desktops Windows XP Prof. with Outlook 2007.

When User A logged in today in the Outlook the email looks normal for this user and email is sent in User A's email name etc..

When User A goes to their Outlook Calendar it say's it is the Calendar for User B (top of Outlook Window).    When User A schedules a meeting with Outlook invite comes in from User B.

I also wanted to mention User A has all of User B's email sent to them since User B is no longer with company for over a year.

Hope that helps clear it up.

User B's calendar is probably shared and opened as a shared calendar on User A's calendar page. User A's calendar is probably not selected to be displayed.

I believe somehow User A's outlook was managing User B's calendar (did have the permission) but user said they did not do that.

Rebooted the Win XP desktop and checked back in a few hours and all was back to normal.  It seems the Oulook Calendar got out of Sync with Exchange 2003 (server was rebooted on Sat. while this Desktop was still logged in (maybe Outlook was open. not sure).
