Our department uses Outlook 2007 on Exchange Server 2003 and our sub department uses Outlook 2003 (recently upgraded from Outlook 2000) on Exchange Server 2003. We are on different domains and recently a staff from the sub department sent an meeting request invitation to our main department staff locating in one of the meeting rooms (resource). However, our main department staff cannot see any options to either accept, decline or tentative on their Outlook 2007.
One of the staff advises there is a message that appears at the top of the e-mail that states This meeting request was updated after this message was sent. You should open a later update or open the item on the calendar. However, he did not receive a later update and cannot open on the calendar.
Has anyone had this issue before and if so, what solution or steps I should take to solve this issue. This happened a few times from the same person.
