Symptoms

In a Microsoft Exchange Server 2016 or Exchange Server 2013 environment, you start the Outlook client in online mode. When you try to select more than about 30 recipients in the Address Book, Outlook generates the following error message:

"The action cannot be completed."

Cause

This issue occurs because some request types aren't defined in Messaging Application Programming Interface (MAPI).
