"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.

You will need to remove the duplicate certificate first by running the following command in the Exchange Managenent Shell:

Remove-ExchangeCertificate -thumbprint <thumbprint>

I would suggest going through the MMC.  Add the certificate snap in with local computer option.

Expand Personal and the certificate will be listed here (double check the thumbprint) and delete it.

Hi Demazter,
i removed the certificate using MMC and assign it again using EMC Pending Certificate Request but still the status didn't chang to assign services.
Glen KnightCommented:
When you completed the pending request did is say it was a success?

If so close and re-open the Exchange Console.  Any change?

Can you right click and select Assign Services?
Tahir-123Author Commented:
It was completed and show success but i cann't assign the service even with right click after re-open EMC.
