    We recently migrated users from Exchange 2003 to Exchange 2010 and users are having problems accessing other user calendars that were shared in 2003 but for some reason are no longer working after migration. I see there is a problem for users trying to access shared calendars from mailboxes on the Exch 2010 from mailboxes on Exch 2003, but this one is slightly different that both mailboxes and calendars are on exchange 2010, has any one else found this problem and is there an fix or workaround?

    The error that the users get back when trying to open the shared calendar is - The connection to the Microsoft Exchange Server is unavailable. Outlook must be online or connected to complete this action.

    When I check the connection status of the users outlook they are online or connected.

    The other problem that the users who are effected have noticed is if they go into the delgates page in the Outlook 2003 option they get a message returned - The delegates page is not available. Unable to access Outlook folder. - The connection to the Microsoft Exchange Server is unavailable. Outlook must be online or connected to complete this action.

    Cheers
