Free/Busy Info

I have a user that is having a problem with Free/Busy Info.  This seems to only affect an existing meeting request.  When he looks at the scheduling assistant, the other attendee has no free/busy info available.  When he creates a new meeting request and chooses that same attendee, he sees that person's free/busy info fine.  I have Emptied his Auto-Complete list in Outlook, but it didn't help.  We are on Exchange 2010 SP2 Update Rollup 7.  User is running Outlook 2010.  Any help is greatly appreciated.

Can you try deleting the meeting request and recreate?

Go to:
Highlight calendar, select Edit and create a new DWORD Value
Give the value name: “UseLegacyFB”

i will have to check with the user when he gets in.  I assume that it is a recurring meeting so i don't want to mess this up without him knowing what i am he is a VP, so i have to make sure i dot my I's and cross my T's...

please try to run outlook using the command line switch "outlook.exe /cleanfreebusy".
This should do the trick.

More info on the available command line switches for Outlook 2010 can be found here:
