Microsoft Lync 2010 – Cannot sign in because the server version is incompatible
Today I decided to change my current OCS client to the new Microsoft Lync 2010 client. Knowing that we currently use Office Communicator Server (OCS), I knew I would run into compatibility issues. Note: Before I carry on, I will have to give credit to a fellow colleague of mine, Ryan Crawcour for pointing me in the right direction for this fix.
Well sure enough, I was presented with the following error:
Entered my Sign-in address and clicked Sign In
Cannot sign in because the server version is incompatible with Microsoft Lync 2010. Contact your support team with this information.
To Fix:
You will need to add a Registry Key to tell the Microsoft Lync 2010 client to ignore the server compatibility check. To do this, follow the steps below.
- Run Regedit (Open command prompt, type Regedit)
- Navigate to HKEY_CURRENT_USER > Software > Policies > Microsoft > Communicator
- Right-Click, Select New > DWORD (32-bit) Value
- Enter Name as DisableServerCheck
- Right-Click on the new Registry key you just created and select Modify
- Enter Value data of 1 (Base = Hexadecimal)
- Click OK
Now when you attempt to sign in again you should be greeted with success!
Enjoy!
