View products that this article applies to.

Symptoms

Consider the following scenario:
  • You have a resource forest and an account forest in a Microsoft Exchange Server environment.
  • A user in the account forest has a linked mailbox (MB1) in the resource forest.
  • You create a mailbox (MB2) in the resource forest.
  • You add MB1 to a mail-enabled security group in the resource forest.
  • You grant the Free/Busy time, subject, location permission for the Calendar folder of MB2 to the security group.
  • The user logs on to MB1 and creates a meeting request, and then clicks the Scheduling Assistant tab in Microsoft Outlook.
  • The user adds MB2 as an attendee.
In this scenario, the user cannot see the details of existing appointments of MB2.

Cause

This issue occurs because the user is not recognized as a member of the security group. Therefore, only default permissions are applied to the user.

    • %ExchangeInstallPath%\ClientAccess\exchweb\Ews\web.config

    <appSettings>
     
    // Add the following line.
           <add key="UseDisabledAccount" value="1" />
     
    </appSettings>
  3. Recycle the MSExchangeOWAAppPool and MSExchangeServicesAppPool application pools. Or, run the iisreset command to reset Internet Information Services (IIS).
