Duplicate Calendars in "My Calendars" Outlook 2007

[adrphibes]

Hello Forum, I have a problem that pops up from time to time.Clients who have delegate access to other peoples mailboxes, sometimes end up with duplicate calendars listed under the "My Calendars" window in Outlook 2007.
These clients are all on an Exchange 2010 mail system and are running Vista or Windows 7 Enterprise Edition.
I have tried removing the troublesome calendar from the users account settings.Both calendars disappear from the list. I will then re-add the offending calendar and sure enough,the 2 duplicate calendars show up again. Now this is not a problem if you simply want to view a calendar that you have been given access to by going to the file menu/Open other users folder/ etc. Those show up in the "Other Peoples calendars" (no duplicates) window just below the main "My Calendars" window.
Again, this only seems to happen to those individuals who have been made Delegates, and have added the Mailbox account via the account settings/Change/More Settings/Advanced tab/ add mailbox..Those who open a calendar by going to File/open other users folder dont end up with duplicates..Hope i didnt make that sound more complicated that necessary.
Any suggestions, or advice would be most welcome...

Thank you

When you are in the Outlook Calendar View on the left of the screen is a list "My Calendars" with all available calendars listed and check boxed by each one. Only check the calendar you want to see.

Thanks for the response to my post. I understand what you're saying..The problem is not getting the calendar to display or shut off,,its the fact that whether checked, or unchecked..there are 2 of them..In other words if you were a delegate to "Calendar A", That calendar would show up twice in the list of checkable calendars.So you would have 2 "Calendar A" options in the My Calendars list. If you click on 1 of them, they will both check and display the actual calendar. Its functional,and only displays the selected calendar once..Its more of a nuisance than a matter of function.
Having said that,,i think i might know what the problem is.
Apparently,,they have been moving mailboxes from one server to another and it looks like it's leaving the old entry. Removing the Calendar,Mailbox etc from the account settings and then re-adding it seems to be working.
Kind of strange,,since i had tried that first and it didnt work..but i tried it on another client machine and it got rid of the duplicate.
I will try it on another when i have the time and see if that resolves the issue. Thank you again for responding to my post, hj..
