"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Right click your server pool and select certificates. Then run throught the wizard and send the request to your local CA. The import step is at the end when it asks you if you want to assign the certificate. Assign your new cert to the pool and your all set

first of all, the Office Communications Server End of Life was on January 8th, 2018, so the communication server will no longer be receiving updates or support from microsoft. so its HIGHLY RECOMMENDED / URGENT ADVICE to upgrade TO Skype for Business or Microsoft Teams (https://products.office.com/en-us/microsoft-teams/group-chat-software).


the steps for renew the certificate is as follows:
  • Click Start > Programs > Administrative Tools. Click Office Communications Server 2007.
  • Select the Enterprise Edition Server.
  • Right-click on the Office Communications Server where the CSR was previously generated. Click Certificates.
  • Click Next. Choose Process the Pending Request and Install the Certificate.
  • Browse for the "CertificateBundle.p7" file that you saved to the server. Make sure to have the search display all files as you search (it only displays ".cer" files by default). Select the "CertificateBundle.p7" file. Click Next.
  • Close the Certificate wizard. The certificate is now installed and is ready for use.
