Hi LukasSMSFT,

 

At this moment i have on my Exchange On-premises the old certificate of "Exchange Delegation Federation" which is expired from last year and i couldn't remove, seems that is a general issue with it.

 

 

My question is now, should i go further with this installation, even if i have these 2 old certificate present, on 2 Exchange servers, because i saw that you have posted this part "MSExchangeServiceHost service may crash repeatedly with Event ID 4999 logged in Windows Application event log. This issue occurs if there are any expired certificates or certificates nearing expiration on the server" ? 

 

 

Looking forward to your response,

 

Thank you in advanced,

 

Gabriel
