You can't share your calendar in Outlook 2007
When you use Microsoft Office Outlook 2007 to share your calendar, you receive the following error message:
You receive this error message only when you use Outlook 2007 and connect to a Microsoft Exchange Server 2013 mailbox or a Microsoft Exchange Online mailbox.
Error while preparing to send sharing message.
Also, if you try to check the permissions on the calendar, you may receive the following error message:
An error occurred when setting schedule permissions.
This issue occurs because of a limitation in how Exchange Server 2013 and Exchange Online set Free/Busy permissions.
To work around this issue, do one of the following:
- Use Outlook on the web (formerly known as Outlook Web App [OWA]) to share the calendar or to set up calendar permissions. For more information about how to do this, see the following Microsoft resources:
- Use a computer that has Outlook 2013 or Outlook 2010 installed to create a temporary Outlook profile. After the profile is set up, you can use Outlook 2013 or Outlook 2010 to send calendar sharing requests and to edit calendar permissions.
