Fixing the Authentication–Related issue with the Outlook

If you are able to receive the emails but can’t send or revert back, you can turn on the authentication switches by adhering to the following procedure.

Checking the Attachment

If the attachments that you may be sent exceed the prescribed limit, you may not be able to send emails in such a scenario. To deal with this, just compress the file using Win Zip or WinRar and try sending the mails.

Verifying that port number is not blocked 

Many a time your ISP may block port 25 which may hinder the mail sending process. So in this scenario, you may use port 587 to redirect the traffic that can eventually take the process of sending mails forward.
