SYMPTOMS

Consider the following scenario : 
  • In Microsoft Outlook 2010, you right-click an Exchange calendar, point to Share, and then click Share Calendar.
  • You add recipients to the To field of the message by typing the recipients' aliases and then accepting the autocomplete suggestions that are provided by Outlook 2010.
  • You send the sharing invitation.
In this scenario, you receive the following prompting message:

The 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:

Contact name <Contact address>

Do you want to send them a copy of this calendar in an e-mail message instead?

YesNo

Some contacts that are listed are internal to your intranet and to your Exchange servers. However, these contacts are listed together with their external address and not with their internal account name.

If you click Yes, you receive the following prompting message:

Send a Calendar via E-mail

Specify the calendar information you want to include.

Calendar: Selected_Calendar

Date Range: Date_Range

Detail: Availability_Information

Advanced:

OKCancel

If you click OK, an email Calendar Sharing message is created that contains an Internet Connection Sharing attachment that contains the calendar data. However, the Internet Connection Sharing file does not let internal recipients share your calendar through the Exchange server. The Connection Sharing file provides only a copy of your calendar's information.

CAUSE

This issue occurs when an internal recipient is also in your Contacts list in Outlook 2010. When you add this recipient to a Calendar Sharing message, the autocomplete feature of Outlook 2010 adds the recipient to the recipient list by using the recipient's external email address. 

For example, a recipient has the Exchange alias User1. When you add them as a recipient to the Calendar Sharing message, their address is displayed as User_name (User1@contoso) and not as User_name.

WORKAROUND

To work around this issue, select internal recipients directly from the global address list. To do this, follow these steps:
  1. In the Sharing invitation, click the To button. The Select names window opens.
  2. In the Address, select Global Address List.
  3. In the Search box, type the recipient's name.
  4. Select the recipient to whom you want to send the invitation, and then click To.
  5. Repeat steps 3 and 4 for each internal Exchange recipient to whom you want to send the invitation.
  6. Click OK, and then click Send.
