System administrators have discovered a cause and solution for this issue. Read more below, including how to correct the system settings causing these issues.


Users are not able to activate Office nor authenticate to Skype. 



UNH IT has found this is may be a result of TLS 1.1 and 1.2 being disabled on the client machine(s). Making sure these two security settings are enabled will be essential in the coming months as companies start disabling support for TLS 1.0.



Enable TLS 1.1 and 1.2:

  1. Go to the Start menu > Control Panel > Internet Options
  2. Click on the Advanced tab (far right tab)
  3. Scroll to the bottom of the settings windows, under Security:
    • Enable (check the box for)

      • Use TLS 1.1
      • Use TLS 1.2
    • Click Apply then OK
  5. If problems persist – disable Use TLS 1.0
    • Follow same instructions for enabling TLS 1.1/1.2, just uncheck use TLS 1.0, make sure to apply settings

Some faculty/staff are currently unable to access UNH resources via older versions of Outlook and Skype for Business. System administrators are aware of the issue and are working to resolve it.

In the interim, users can access UNH Exchange email via the Outlook Web App at https://exchange.unh.edu/

Users accessing these resources via Office 2016 or Office 365 ProPlus are not experiencing this issue. UNH IT recommends upgrading to the most recent version of Office, which is available to all UNH users under existing licensing agreements. To upgrade, please see below:

Managed Desktops (with Software Center):

  1. Close Office products
  2. Hit the Windows key and type Software Center
  3. Choose the “Office 365 ProPlus” application
  4. Click Install

Unmanaged Desktops:

  1. Uninstall Office, https://www.unh.edu/it/kb/article/uninstall-office-applications.html
