Error 0x800ccc01 (Content of the certificate invalid)

[blindsleeper]

I can receive mail via Outlook Express but cannot send!

I get this error message "Content of the certificate invalid 0x800ccc01,
request a renewal of the certificate from your server security

What to do?

It seems to be due to the Anti-Virus or Spam filter that your user has got on his machine. Ask him to disable spam fighter and then check if it works.

You've not changed anything on any of our servers recently so there should not not be any certificate related problem. You are most welcome to open a ticket if problem continues even after disabling spam fighter.

Hello,

I think you should get your certificate re-issued by your authority server.
