This is a quick post on renewing the Microsoft Exchange Hybrid Server Certificate for your connection to Office 365.
This is actually incredibly easy to do. If you are simply renewing the existing certificate, go through the motions in GoDaddy or whatever provider you use and get the certificate installed on the local computer certificate store on the Exchange server.
Once you have done this check that the name of the existing certificate in Exchange matches the name of the renewed certificate. You can see my notepad document with the name of the renewed certificate below against the existing one in Exchange.
If this is the same then all you have to do is enable the SMTP and IIS services on this certificate – and that is it.
If you are changing the certificate name the way to do this would be to re-run the Hybrid Configuration Wizard tool and choose the new certificate when prompted.
HI ,
If i have 2 Exchange 2013 hybrid servers and need to renew , does it require downtime or do i need to put one serve rin maintenance install certificate run HCW wizard and then out from maintenance .. or like what is the procedure .?
I just did this and it requires no downtime. All the email backed up in the queue will be forwarded after you rerun the HCW in about 5-10 min after completion. I made the mistake of updating the server cert, but not running the HCW afterwards.
Hi Trey,
Thanks for you reply ..it seems if i am not changing cert provider from geocert to GoDaddy or to others then seems no need to run HCW.
Last time i changed due to some issue and ran HCW..as this time renew from same provider then i hope no need ..
Can someone please confirm this ?
