Consider the following scenario:
- The Simple Mail Transfer Protocol (SMTP) address of your user account contains uppercase and lowercase letters.
- You configure Microsoft Lync 2013 to use Microsoft Exchange or Microsoft Outlook to update your presence information.
- You create an "Out of Office" (OOF) message in Outlook.
This issue occurs because your Lync 2013 client is not recognized as the preferred endpoint.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
