I have several sites that were configured and working correctly - sending mail as expected - (all slightly different 9.x CE versions), right up until the last ~15 days or so - I'm not sure exactly what date they stopped working. Some use the DNN Feedback module, some using 3rd party module (Action Form).
Now, none of them work, and thus far have not found any solutions. Has anyone else experienced this, and have you been able to resolve? Thank you!
Thank you for your response - it turned out to be 'none of the above'. It had been working quite well for some time, however it was setup using a shared mailbox. Apparently, I got away for free for a while, until MS did a sweep. What I missed during setup was the following key line in the MS documentation: Mailbox: You must have a licensed Office 365 mailbox to send email from.
I didn't see that line, and it worked perfectly for quite a while, so I never gave it another thought. So the fix is to make this mailbox a paid licence. I confirmed that it works using a different paid license mailbox.
The Microsoft document is here: https://docs.microsoft.co...th-client-submission
Thanks again!
I'm glad you worked it out, and thanks for sharing your solution. :)
We are having a simliar issue we upgraded to DDN 09.07.02
We have a office 365 lincence the work and is receiving email but when we us is to send email from the web site we get an error
User is not authorized to relay messages through the server But we can happy send an email from the user to the user As a work around we have a gmail account forwarding emails to the clients email
May I add a shameless plug for DNN 9.9.0? We are close to releasing this exiting version which has a new mail provider and better support for O365. See https://github.com/dnnsof...ases/tag/v9.9.0-rc2.
