Did you set Outlook as Personal Information Manager in the Office Communicator Options?
Deli
Yes I did..
What version of Outlook and Communicator are you using?
So when you click a contact in Communicator and select send an email it just hangs?
Aiii sorry made a mistake.. It is from Live Meeting, from inside a opened meeting. When I choose "Invite by e-mail".
Don't really know if you can set the default email client from Live Meeting client
You should check your default email client settings in Internet Explorer!
