Multiple calendars open at once in Outlook 2010

Question

Hello,
We've been experiencing a new issue with a small set of users (5).  When they select the Calendar from Outlook 2010, multiple calendars are displayed at once.  These users have rights to the accounts of other users and even though those calendars
are unchecked from their last view, those other calendars continue to appear all at once.  I have switched users from Outlook 2010 32bit to Outlook 2010 64bit.  Their release levels are all 14.0.7015.1000.  The Exchange 2010 backend is running
SP3 with Rollup 5 and we do not use any PSTs.  No clients are running in cached mode as that is disabled by group policy.
Has anyone else experienced that?  I've seen posts on how to get multiple calendars to consistently open but nothing on the opposite.
Thank you,

Hi,
Generally, Outlook 2010 can remember the selected Calendar when you last use Outlook and would reselected them at next start-up.
If your Outlook automatically displays multiple calendars which are not selected in last view when you open Outlook, please do the following changes to have a try:
1. Check whether the issue also occurs when you change a computer.
2. Run Outlook /cleanviews switch to start Outlook to check whether the issue persists.
3. If the issue continues, please start Outlook in safe mode to check whether the issue is caused by any third-party add-ins.
