Dear all, I'm just asking if there any way to remove SMTPS from exchange services, I was add " enable-exchagecertificate -thumbprint <> -services: "SMTP,POP,IMAP,IIS" after that I got error number 0x8007005 "you don't have permission to perform the operation" also i can't access to mail via outlook 2007 any help please!

Hi, You could try the remove-exchangecertificate cmdlet, but I am not sure if that will fix your problem. Were you able to access your mails before you executed the command? Leif

when I try to remove exchange certificate, the messege told me you can't remove default certificate so, i create new exchane certificate and I do as you told me,..... its work and many thaks to you Ghaith
