Hi,<br />
<br />
I'm currently installing Exchange 2010 and experimenting with it using Outlook 2007.<br />
<br />
The weird thing now is that I am able to share a newly created Exchange calendar with some other guy here but he's not able to share one of his newly created Exchange calendars with me. He gets an error saying that calendar sharing is not available for the following e-mail addresses due to the authorization parameters on the server?<br />
<br />
Which parameters are these? And why can I share my calender anyway?<br />
<br />
Thanks a lot!
