Connect Lync 2013 to OCS 2007 Infrastructure

As most of you know Microsoft released their new Office 2013 suite. The new Lync 2013 client is included with Office 2013. But if you are like me I connect to multiple environments and not all of them are updated or running the latest server build. Here is a quick guide on how to connect your new Lync 2013 client to your OCS 2007 or OCS 2007 R2 environment.

  1. Install Lync 2013 client.
  2. Configure it and try to connect to your environment. (Use your emailaddres@domain.com) for the login information.
  3. You will receive and error similar to this one.

  4. Open RegEdit and create a new key to disable the server version check. For 32 bit: HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftOffice15.0Lync  or 64bit
    HKEY_LOCAL_MACHINESOFTWAREWow6432NodePoliciesMicrosoftOffice15.0LyncDisableServerCheck

  5. Exit the Lync 2013 client.
  6. Try to login again.
  7. You should be successful to log in.

  1. There is a simular trick to connect a Lync 2010 client. I recall that Livemeeting and the adressbook weren’t working in that setup. Can you confirm that they do work in combination with the Lync 2013 client? That would be cool. Thanks! Gr Johan

  2. Connects fine, however I get this error when I try to expand a contact group (even after re-adding the group)

    “Use of the distribution group service is restricted and requires specific permissions”

  3. Normally I would agree, however the lists load fine the MOC 2007 R2 client (verified after I closed Lync, my lists were missing in MOC, so I had to re-add them to MOC. Repoulated without an issue. Does not work in lync still)

  5. Thanks for the instructions, worked a treat on Windows 8 (64 bit) running Office 2013, especially after reading Jason’s comment on restarting.

  7. This works great for me, is there a way I can get the Lync 2013 mobile app in iOS to connect to our On-Prem OCS Server as oppose to Office 365 as well? I played around with it but could not get it connected.

  8. Thank you It helped me.
    There was no key named Office under Microsoft. I added all the below and restarted the system it worked.
    This is what I have done.

    Windows Registry Editor Version 5.00

    [HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftOffice15.0Lync]
    “DisableServerCheck”=dword:00000001

  9. Update: After many months using this tip, we have come across something that no longer functions.

    We have an account we use as our main contact number for help desk calls, and setup with Ring Team/Delegates. If you use Lync 2010 client to connect to OCS 2007R2, the DB will keep the version stamp of the client and prohibit the client from using these features. So far the only fix I have found is to remove the OCS user and reprovision the account. Make sure you backup the contacts if they are important, before you reprovision.

  10. So, this is fabulous, and has been working for awhile – One thing I noticed is that the Outlook Conferencing Add In is now slimmed down – the conference call feature is removed by the Lync install. Has anyone found a way to get this back to how it was originally with the Live Meeting Add in? We haven’t deployed Lync servers yet, so I need to continue having Conferencing capabilities.

    • In the Lync Client you received a pop-up window that ask you if you want to save your credentials say yes. Also in the username try the domainusername combination.

      • I have Outlook 2010 and not sure whether I will be able to get 2013 as its specified by work. I get a notification below ‘cannot synchronize address book’. So when I search for a contact I get ‘no matches’.. Any help would be much appreciated.

        Thanks

        • I used to get that same issue. When I upgrade to Office 2013 it disappear. There It says that is not syncing but everything works ok. Some people have issues with group chats and it is the permissions.

  11. Tanks for Your tip 🙂 It worked Perfect, but im also have issues With the contact list, i would like to use “Exchange” distibution list.. But when i add them – they are empty…

  12. Regedit worked like a charm for me. Two issues still plague me , 1. New users are not searchable within Lync, they must sign into legacy OC2007 first then they will work in LYNC2013. 2. Some users find when starting group chats, IM has been disabled. Desperate for fixes or work around. Please.

    • New users will not appear in Lync because the Address book has not been updated. This process happens normally every 24 hours or you can run it manually via Powershell with the Update-CSAddressBook command.

  13. this is working fine but when i expand any group after login to lync it gives me below error
    use of distribution group service is restricted and required specific permission
    Any workaround to resolve this?

  15. Any chance you know how to make this fix work with the Lync 2013 App for Windows 8.1 (32-bit). Trying to use on my Asus Transformer T100

  16. Hi Carlos! Your Lync 2013 to run for OCS 2007 is great! Though I have one problem, and that is to access my Outlook from work. Do you have a way to do it? Outlook at work is MS 2007 or 2010.
