Is Mail.dll compatible with Outlook 2010? [closed]

Question

mail.dll is apparently integrated into my ERP software - M1 but i cannot successfully connect to the SMTP server using Outlook 2010 through M1.

I get the error message :-

"Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. (Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host."

M1 report to me that testing was done with Outlook 365, but this forum indicates that mail.dll :-

"IMAP and POP3 are standard protocols and Mail.dll supports both of them fully. It was tested against all major email providers like Gmail, Outlook, Yahoo, QQ and major server software like Exchange, Dovecot, hMailServer."

So i take it that mail.dll is compatible with Outlook 2010

So I am looking for suggestions to get this working and firstly need to determine if it is an M1 issue or a dll compatibility issue.

Help would be appreciated

Mail client you are using has nothing to do with being able to connect to SMTP server by a different application.
