SMTP Mail not working since 17.1 update

Hello,

Since the Business Central 17.1 update, users are not receiving any e-mail workflow approval notifications. The SMTP mail settings are correct and when sending a test e-mail this is successful.

Our 'Training' company has an identical setup and notifications are coming through here as normal. I have disable / re-enabled the workflows, tried changing to specific approver, both with no joy. Any suggestions would be appreciated.

Many thanks,

There were some changes in the email handling with the update from the legacy SMTP:

Hi Ron,

Thank you - I did review this article, however it states that the legacy SMTP settings should still work. When the new SMTP - e-mail extension is enabled by default, legacy SMTP settings will be copied across. I have not yet enabled the new extension. The settings are replicated in our training company which has no issues with workflow notifications.

Additionally, I have noticed that the following error is displaying in the Job Queue Entry Log since 26th November:

“The User Setup does not exist. Identification fields and values: User ID=’’ “

The approval user setup / user setup have not changed, and there in an entry in there for each user, complete with e-mail addresses etc. so I'm unsure what is causing this error.

Many thanks,

Hello,

Could you please add the user's in the User Setup or Approval User Setup and add their E-mail address in the last column. I just ran the scenario myself with enhanced E-mail settings enabled and I had to manually create the SMTP User account in Email accounts (as SMTP was not setup for my new company). After that, test email started to work again.

It seems to be complaining about that part missing in the setup. Maybe this part did not yet fully copy over.

If the scenario still does not work, we kindly ask you to raise it to Microsoft support as we could be facing an unwanted scenario that we did not catch in our testing.

Thanks.

Hi Marco,

Thank you for your suggestions. I can confirm that the e-mail addresses are in the User / Approval User Setup tables. The SMTP account is present in both the legacy SMTP settings as well as the E-mail Settings, and the test e-mail feature is working in both of these areas, yet the problem with the notifications still persists.

I will raise the ticket with Microsoft support as you suggest.

Many thanks,

Luke,

I was on with Microsoft Techs yesterday and was told to do this. I have not been able to implement changes yet due to delegated authority permissions, but it might work for you.

Hi Candace,

Thank you - having reviewed the article, I can confirm that our settings are correct and that Business Central is authenticating with Exchange Online.

We have an open ticket with Microsoft and will update on the resolution.

Many thanks,

Marco we are getting this error, since the update and Microsoft cant figure it out. Can you help. This happens when we are sending emails to customers for invoices or posted invoices.
