Hi everyone,
If we dispatch Invoices directly out of Business Central, we get an error that the mailserver is not supporting authentication.
We have four companys and only one have a problem with that server.
we use ionos as mail service.
We have a "specific User", SMTP server is the smtp.ionos.de Server. Port 465
I try Basic, OAuth2.0 - error changed to no Plugin support that and Anonymous. And i try every of that combinations with secure connection and without.
I´m not sure what the error is. Maybe it´s after an update because we never change the seetings.
Hope one of you guys had an idea or maybe a solution for that.
Thanks everyone!
