Hi sameer.aw, If you have a self signed certificate then you must install this certificate as trusted root certification authorities in users machine´s that uses outlook anywhere. You must make this install using mmc=>add snap-in=>certificates pointing to local machine. Regards

I would highly recommend that you use 3rd party certificates instead on your own CA going forward.

hi thanks for reply Is there any way can outlook anywhere users get the certificate automatical, outlook anywhere users are in workgroup and they are at remote location.

Agree with Andy, 3rd party certificate is a better choice. Sameer, if you want to renew the CA certificate, you can create a new CA certificate, then import and enable it. If you use Get-ExchangeCertificate -thumbprint “C5DD5B60949267AD624618D8492C4C5281FDD10F” | New-ExchangeCertificate, it will be created a new self-signed certificate.

I can’t use 3rd party certificate now. My exchange server certificate will expire in next 7 days i want to renew certificate without harming any outlook anywhere users so please tell me is there any possibility. I am using my Internal CA server. please also provide me step by step document how perform.
