AOL PIC Users Fail / Presence Unknown

As all are aware Office Communication Server 2007 R2 was recently released and with it the ability to run the various code on Windows Server 2008 64bit. Everything appears to run/work correctly with the exception of AOL users via the PIC.

Symptoms:

  • AOL Users' Presence is Inaccurate; it may show on-line, unavailable, or presence unknown
  • A message invite may be received from an AOL user but no information is ever received
  • Attempting to respond to an AOL user or start a conversation with an AOL user will fail

The fix was discovered by Microsoft Senior Escalation Engineer Scott Oseychik among others and is documented at:

The fix: in short you must modify the local security policy on the 2008 Edge server rearranging the TLS authentication methods. It is important to note that this fix and the issue do not apply if you have the OCS 2007 R2 bits installed on a Windows Server 2003 64-bit.

Yahoo! Service Outage for PIC Users

Yahoo! will be undergoing an emergency maintenance from 4:30pm to 4:30am PST. During this period, users will see intermittent presence issues. All other functionality will not be impacted.

More Information:

After the maintenance window expires, if you find you are still having issues, please first log out & then back into your Communicator client. If the issue still reproduces/occurs for you, please restart Edge Front-End services first. Allow me to apologize for this up front; I understand this will require an “emergency service restart change request” for some of you. If all this fails to resolve the PIC issue between your LCS/OCS deployment and Yahoo!, please engage Microsoft Customer Support Services. Premier customers: please leverage your Technical Account Manager to initiate the case creation process. Please be prepared to supply Edge Server logs, remote access via our EasyAssist applications from MSFT, and we will do our best to investigate and resolve this in a timely manner.
