Warning: email address does not appear to be valid?
I wrote an email to my accountant this morning, but when I clicked the send icon I got this message:
Warning
"(name of recipient)" does not appear to be a valid email address. Verify the address and try again.
I know the email address is valid. My accountants' office has not changed their email address. I have never gotten this message for anyone before, so why would I get it now?
