Hi, Guys.

Need your assistance on how to renew the certificate in an Exchange server 2010 if it is about to expire?

How is the process/procedure? Would there be any outage while doing that? What is the possible impact on this on the clients? Please advise.

Your inputs is much appreciated here.

Thank you.

BR,

Irwin

Hi IrwinBats,

I have already answered your question:

Please let us know if this helps.

Hi, Zach / Will. Good Day! Thank you for your reply and information. However, what I want is a comprehensive process together with the potential risk with it if not done properly. Ensuring that by doing this, it doesn't' create any outage on the clients. Further, what are the requirements to complete the task. Where do the certificate request and the actual certificate itself come into play? When to assign services to the renewed certificate? Is it okay not to remove the old, existing certificate if the renewed certificate is already in place as well? Does this create conflict between the two because they co-exist? Please advise Thank you. BR, Irwin

Hi irwinBats,

Thank you for your question.

I agree with Zach, you could refer to the link which Zach provide to renew certificate.

what I want is a comprehensive process together with the potential risk with it if not done properly. Ensuring that by doing this, it doesn't' create any outage on the clients. Further, what are the requirements to complete the task. Where do the certificate request and the actual certificate itself come into play? 

A: we could renew the certificate request on Exchange server, then apply a new certificate from CA, then import to Exchange server. 

When to assign services to the renewed certificate? 

A: we suggest you renew the certificate out of production hour and do some tests. 

Is it okay not to remove the old, existing certificate if the renewed certificate is already in place as well? 

A: it is ok not to remove the old, existing certificate if the renewed the certificate is already in place. 

Does this create conflict between the two because they co-exist? 

A: because we have replace the old certificate, so old certificate is offline, we suggest you remove it.

Hi, Jim.

Good Day!

Thank you for your replies to my queries. Appreciate it.

My another concern is to determine the necessary testings needed for ActiveSync, OWA, Outlook, and SMTP after you have renewed the wildcard certificate in Exchange 2010 servers. Please advise.

Thank you.
