We are running Exchange Server 2007 with MS Outlook 2007. One of our users is trying to share out an executive calendar. She is able to share it with all but two people. The two people who cannot view it get the following error...The "Admin Calendar" was shared with some of the recipients. However, calendar sharing is not available with the following entries because of permission settings on your network.I've verified that both of these individuals are set as reviewers for this calendar. Any ideas?

Hi,Would you please let me know whether the two users belong to another AD forest. Based on my research, the error mostly occurs when attempting to share calendar folder cross forest? In addition, would you please let me know howthe user share his calendar folder? Whether he set calendar folder permission directly to allow others to access the folder or the user click Share My Calendar to send a share message to the two users? ~~~~~~~~~~~~~~~~ Mike Shen TechNet Subscriber Support in forum If you have any feedback on our support, please contact tngfb@microsoft.com ~~~~~~~~~~~~~~~~
