Given you have a sharepoint meeting workspace with a recurring meeting linked to Outlook and the meeting occurs every Monday at 1pm
Is it possible to add an additional meeting date to that workspace, like a one-of Tuesday meeting at 2pm?
Yes it's possible, I just tried it and it works fine to me. But I have office 2010.
Edit: I have a recuring meeting every morning at 9. So from monday to friday, I'm not available for an hour. What I've done, I went in Sharepoint, setup another meeting apointment with another person and it works fine. The only thing I have is 2 meeting at the same time but Outlook let it go thru. As I said, I have Office 2010 so maybe the functionnality is not the same as 2003/07.
