A user at a client I am working for has a strange problem with Outlook meeting requests. She is using Outlook 2003 with Exchange 2000 as a back end. She manages a recurring series of meetings whose instances and attendees change frequently. Some of the attendees are external contacts with (contact) entries in the GAL. She is a delegate of some of the people she is inviting (some of which are Mac Entourage users) and I suspect that some of the external contacts are delegates for some of the other external contacts.
Her issue is that, after she has sent meeting updates and received responses, if she then opens the meeting again to amend and send further updates, she frequently finds that some of the external contacts have been added again as duplicate attendees. Sometimes as required attendees but more often as optional ones.
There’s an awful lot of things in the mix here and plenty of noise to filter out. What I am particularly puzzled over, though, is under what circumstances Outlook/Exchange would add optional attendees when she hadn’t explicitly added any herself.
Any ideas?
