Try asking in an Exchange group - admin is probably a good place to start.

After furious head scratching, FJCarson asked:

| I have users using Outlook 2007.
|
| We are in transition of moving from Exchange 2003 to Exchnage 2007.
|
| The issue that I'm having is that any users that has a mailbox on
| Exchange 2007 cannot see the schedules of people that have mailboxes
| on Exchange 2003 in Outlook Group Schedules.
|
| I really need to have this to function correctly.
|
| Any assistance would be greatly appreciated. Thank you.
