Exchange 2013 – empty page after log in to the browser

Starting with Exchange 2013, the administration mainly happens via the browser. Of course except you work with PowerShell.

But if I assign a new certificate to an Exchange Server 2013, I get an empty page after having logged in to the administration console.

6 steps  – Fix the empty page after log in

Assigning a new certificate leaded to an empty page after having logged in to the administration console (https://server/ecp).
As the problem did not exist before, there must be something wrong with the certificate, I thought.
The next thing was to check the Eventlog to see what error occured.

Empty page after log in to Exchange 2013 – due to new certificate

 
In the Eventlog I got the following error message:

To solve this problem, I had to delete the assignment of the old certificate in IIS and assign it anew.
Afterwards, the Exchange administration website worked again.
 

 And these are the 6 steps:

1. Read out certificates: netsh http show sslcert
   
    
2. Copy and save content
   
    
3. Delete the certificate causing errors
   
    
4. Read out the certificate hash from the certificate
   
    
5. Assign new certificate: netsh http add sslcert ipport=0.0.0.0:444 certhash=XXXXXX  appid=”{XXXXXXX}”
   
    
6. Operate IISRESET

If you follow these steps the Exchange 2013 console should then work correctly.

Good luck!
