Lync 2010 Self singed Certificate expired

Hello,

Our Lync Self Signed certificate was expired last week.  I could find the way to renew the license.

I need help or document for the steps to renew the license.

Regards,
Mohsin

Hi,

Self Sign Certificate is not supported for Lync Deployment.

Do you mean renewing certificate from you own Enterprise CA?

You need to run Step 3 from the Deployment Wizard.  Here are the steps:

Thats right, you will need to request, assign, and install the new certificates through the Deployment Wizard.

Moreover, here is an article about How To Renew or Create New Certificate Signing Request While Another Certificate Is Currently Installed. Hope it is useful.

you cannot have self signed certificate in lync, if you mean certificate in front end server from internal ca, it will automatically renew from your ca.

and if you mean certificate on edge which is issued from internal ca you must manually renew it.

tell us what you mean in self signed certificate .... we will help you more deeply after it :) .

Hi Mohsin,

As rightly mentioned by other members... self signed certificate is not supported for Lync. You need to grab another certificate to avoid any unknown issues with Lync.

This is my issue also.  My cert has expired.  The Deployment wizard will not allow me to renew a cert that has already expired.  The message says I need to Request a new one.  How is this done?
