Exchange Certificate - Revocation Check Failed

Hi,

the scenario is the following:

• Windows 2012 R2 domain
• Exchange 2010
• Windows 2012 R2 PKI (1 CA Root stand alone. 1 CA Subordinate Enterprise)

At Exchange, I get the following error:

The certificate details are:

I guess that revocation check error is due to "%20" at ldap path (second image).

The questions are:

The "%20" is a normal behavior at "CRL Distribution Points" details in the certificate?

if no

How to delete "%20" in the certificate?

Thanks in advance!
