Ocs presence not updating
Here is a breakdown of three major known issues and what to do about them.
The most common problem was introduced in the recent September 2013 update package for the Lync 2013 client.
In my experience the Presence for some contacts shows as Unknown or Offline, however it can also cause some Contacts to go missing from the contact list, and to not display their Presence in Outlook.
The resolution is simple enough – delete the SIP profile directory and restart the client.
Some of the reported problems are: This issue is easy to miss because it is published under the heading Script to delete SIP profile for multiple Lync 2013 users (by Edwin Joseph) on Microsoft Next Hop.
In a nutshell, the Lync 2013 Windows client maintains a local cache of the address book and they can get in a state that causes a variety of issues with the Contact List in the Lync 2013 client.
November 13, 2013 Update: the presence issues with Exchange free/busy that were introduced in the September 2013 Lync 2013 Client update have now been fixed in the November 2013 Update; see Lync 2013 November Update – A Much Anticipated Client Fix.
Recently there as been many reports of Presence issues with the Lync 2013 client.
In the meantime uninstalling the September 2013 Update and/or rolling back to the August 2013 Lync update resolves the issue.
There have been other issues reported after applying this update, but it has not been determined what exactly the combination of factors introduce the issue.
If your Lync 2013 client has the September 2013 update installed your Lync client version will be 15.0.4535.1002.
This issue is being actively being investigated by the Lync team at Microsoft so stay tuned.
The issue is documented in this support KB article: Presence status isn’t updated based on Exchange calendar in Lync 2013.
In a nutshell there is an issue with the integration between the Lync 2013 client and Exchange which impacts the synchronization between the Lync 2013 client and the Outlook calendar information (such as “in a meeting”) and the Out-Of-Office status.
