Hi,

Kindly check with your local IT support team about the license.

They can update you about the validity of your user ID which is used as sender ID.

I´m using D365 FO, and if it is relevant, version 10.0.12 . And yes, some days it is working and some days it´s not. Before september 15th it was working properly, now it´s working as I explained.

I would really appreciate any help.

Since you are not specified version you are using (D365FO /AX On Prem or Cloud Version ) check following

Double check your SMTP Server if you are using office 365 most of the cases it should be smtp.office365.com

And Port should be 587 , also enable option(for D365FO) Specify if SSL Required

if you are using AX2012 then use this thread : https://community.dynamics.com/ax/f/microsoft-dynamics-ax-forum/91673/configuring-ax-2012-mail-to-office-365
also, Note if you are using on-premises versions check you allowed necessary ports , URLs from your Firewall.

from office 365 side just check your email account has an active subscription and valid License, hope you are not using user@xxx.onmicrosoft.com email address because its not recommended and has some issues : https://docs.microsoft.com/en-us/archive/blogs/latam/o365-spam-abuse-ndr

if you need detailed information refer : https://docs.microsoft.com/en-us/exchange/mail-flow-best-practices/how-to-set-up-a-multifunction-device-or-application-to-send-email-using-microsoft-365-or-office-365

Hope this help

Hi André,

I´m using Exchange as a "batch email provider". This is my current settings:

SMTP settings:

I have used Test email option with "Exchange" email provider, and it works.
