One of our clients is on GP2016 R2, and late last week their system quit generating the automatic e-mail that comes from EFT processing. Their e-mail runs through Office 365. Nothing that I am aware of has changed in GP, their environment or network. Given that, have there been any changes in the Office 365 environment that could have impacted GP's e-mail?
Please advise. I am open to suggestions. Thank you.

To add on to what has been suggested here........
As you're aware, there has been talk of completely removing basic authentication from O365/Exchange Online for the last couple of years. It was supposed to already have been done but got pushed back due to covid and such.
Currently, Exchange Online/O365 have put a deadline that as of October 2022, basic authentication will be permanently disabled moving forward.
Why this is important to us, is that our Exchange emailing in Dynamics GP 18.3 and prior, requires basic authentication to be enabled on Exchange, in order to authenticate.
However, in the last couple of weeks, we've become aware that Exchange has been disabling basic authentication on some O365 tenants to prepare for the permanent disabling and this can last anywhere from 24 to 48 hours. Some of this is mentioned in these two articles:
techcommunity.microsoft.com/.../2772210
techcommunity.microsoft.com/.../2599824
These articles mention a work-around that you can potentially look into, that allows you to use a legacy endpoint to connect to Exchange Online, which still uses basic authentication, which will be valid until October 2022 when basic authentication is removed completely.
Exchange Online is making these changes not on the policy level but behind the scenes, this is why it is possible to run a diagnostic against your Exchange Online and have it show basic authentication is still enabled, when it actually is not behind the scenes. This makes troubleshooting basic authentication near impossible for us right now.
For Dynamics GP, we've also seen this work-around work for some customers, to use basic authentication still, while emailing via Exchange, until they can upgrade to GP 18.4 and use our new modern authentication/MFA functionality. The blog mentioning this is here:
All of this being said, the recommendation is to get upgraded to Dynamics GP 18.4 and begin using our new modern authentication/MFA feature we added to Dynamics GP. Along with using modern authentication and not basic auth, it also allows users to have MFA enabled on their user accounts, whereas MFA was not supported when emailing per Exchange in prior versions of Dynamics GP. This is mentioned in these two blogs:
docs.microsoft.com/.../multi-factor-authentication
community.dynamics.com/.../microsoft-dynamics-gp-fall-2020---multi-factor-authentication
By Oct 2022, you must be on GP 18.3 or later, using modern authentication, in order to email per Exchange, otherwise MAPI would be the only other option, which requires a 32-bit email application.
Let me know if you have any questions........
Thank you
You may be running into TLS issues. It is going to be a rough year for e-mail due to the TLS changes happening this year. The clear message from Microsoft GP Support is to get on the current release of GP before the fall cut-over.
