Lately while working with my Exchange 2010 customers they complain “ Exchange 2010 Management Console is very slow”, and I have been advising them about a workaround that had worked perfectly for me and them all the time. Now the management console starts very quickly . So here is the solution:

 

Turn off (Uncheck) “Check for publisher’s certificate revocation” & “Check for server certificate revocation” options on the server/workstations you are starting the EMC (Exchange Management Console) on

·        In Windows Internet Explorer –> Tools –> Internet Options –> Advanced tab

·        In the Security section, uncheck the below two options “Check for publisher’s certificate revocation” & “Check for server certificate revocation”

 

How does this relate to the EMC in Exchange 2010  ? well Exchange tries to connect to the certificate revocation list (CRL) Web site. Exchange examines the CRL list to verify the code signing certificate.

 

I have also noticed that unchecking the two options above speed up the start time of EMS (Exchange Management Shell)

 

This is a security option and unchecking this represent a risk unless the machine is in a secure environment, please be aware the of consciences of this change.
