While trying to create mailbox this error appears.

Exchange management tools powershell connects without a problem.

Exchange 2013 with solidCPServer has access to internet for revocation checks.

solidCPPortal + SolidCPEnterpise server also has access to internet.

at ECP panel I’ve changed internal url from http to https://mail.internal.fqdn/powershell and checked Integrated Windows Authentication

 

Error creating mailbox. See audit log for more details.
