Cannot send Emails

[shalmaxb]

Hello, I am not able to send Mails anymore. When sending the mail it throws error, that credentials are incorrect. But they are not, I tried every constellation and in the Grpoup Email Account I can send Tests, which pass without problems.
The error log says the same: Wrong credentials.
My espoCRM Version is 9.1.7

I solved it meanwhile. But I think, it could be a bug.

1. Deleted the group email account and created a new one. In the new one I changed the SMTP credentials. It had no effect, From Grpoup Account configuration I could successfully send the tests.
But in the Email entity it threw still the error, that the credentials are wrong.
2. I had a look into the database under table email_account. There had not been inserted the recent created new Group Account and because of that this account still had the old SMTP cerdentials in the database.
3. I deleted the database record and the Group Email Account again, created again a new Group Email Account and that worked.
