Sending Emails Through Outlook
Hi!
I am trying to correspond with an instructor at school. I have to use their microsoft outlook email. When I send emails, I get an error that says, "This message has a digital signature, but it wasn't verified because the S/MIME control isn't currently supported for your browser or platform."
What is this and can I fix it so I can use their platform?
