I have strange problem in that all of a sudden Outlook refuses to send attachments. I've disabled Comodo which I use for security. I also tried creating a new profile and switching to that profile but that didn't work.
pop/smtp is the the only method configured and my service provider assures me they're not blocking it.
Mail without attachments works fine.
Any suggestions as to what I can try to resolve this?
OS is Windows 7.
Thanks in advance.
