Recently, however, we facilitated the configuration of a POP3 access for our clients who wished to use Microsoft Outlook. Everything was working normally, except that an error occurs every time we send emails to outdoor domains.
Please see the attached image for the illustration of the error.
I have already checked all the confirmation settings in Outlook that might look similar to those that can be found in the Domino server so that the issue can be resolved, but I haven't had much luck.
Please help me find a way to solve this problem.
Thanks a lot, everyone!
