Use Skype for Business with older Lync Servers (Fix for error: Server version is incompatible)

Skype for Business 2013 or 2016 will throw this error if you try to use it with older Lync servers.

Cannot sign in because the server version is incompatible with Skype for Business.


Fix: Add DisableServerCheck registry key. Reboot your computer (to reload the HKEY_LOCAL_MACHINE registry hive). Your Skype for Business client will work after reboot.

Key: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Office\16.0\lync
Name:  DisableServerCheck
Value: 1 (00000001)

You may download this file (right click the downloaded file and select Merge to add to the registry).

Office: “Add to dictionary” option greyed out

I have helped someone with their Word (& PowerPoint) for not able to add custom words into Dictionary. When the user selected an word and right click, the option for Add to dictionary is greyed out like below picture.


Fix/Solution: Add a Custom Dictionary and select a language in Proofing options.

  1. Click File –> Options
  2. Select Proofing –> Custom Dictionaries
  3. Select the CUSTOM.DIC and a Language (English (United States) in my case) if not selected. If you don’t see your language, add it.


4. That’s all. Click OK’s to close all dialog boxes. Your problem is fixed. You can now add words into custom dictionary.
