Exchange 2010 Calendar Sharing Error
When any users try to share calendars out, they get the following error message in a dialogue box:
"error while preparing to send sharing message"
I don't get any more information than that. Some stuff I've read has pointed to an issue with the autodiscovery running within IIS7.0. Has anyone else seen this issue before?
Edit: It might be worth noting that this error only happens when using Outlook 2010. when users have used OWA then this doesn't seem to be an issue.
