Lync Conversation History Not Working RRS feed

  • Question

  • Conversation history with Lync is not working for most of my users.  It does work for me but often will stop working for some unknown reason.  From what i was able to gather Lync does not use SCP to discover Exch, instead autodiscover (DNS) is used.  My setup is not like a normal setup and this is where my question comes in to play.

    My Setup 

    1 Exchange server does all roles

    1 Lync server

    AD domain is

    email smtp is as primary, smtp exist but not used

    OWA URL is which is certed for only

    Lync uses the users smtp address ( to discover exchange.

  • Hi,

    You could first check the following points:

    a. Press Ctrl and right click Lync icon in the taskbar, open configuration information. On the open page check if EWS status and MAPI status are OK. And try to access the EWS URL: https://<ews>

    b. Try to delete SFB client user profile and then test the issue again:


    c. Try to rebuild the conversation history folder in Outlook client:

    Backup your old “Conversation History” folder contains in Outlook (export it to a file),

    Delete the “Conversation History” folder and close “outlook”,

    Make sure that Lync and outlook are completely closed,

    Start “run” and type in “outlook /resetfolders”.
