Emails are not send when changing from O365 tenant

Self-Hosted | v5

I changed with my mailbox from one O365 tenant to another 0365 tenant.
The account email address and password is the same but I always get the following error in my invoiceninja.log

[2023-03-17 16:07:49] production.INFO: error failed with Failed to authenticate on SMTP server with username “info@servitweb.be” using the following authenticators: “LOGIN”, “XOAUTH2”. Authenticator “LOGIN” returned “Expected response code “235” but got code “535”, with message “535 5.7.3 Authentication unsuccessful [AM0PR02CA0075.eurprd02.prod.outlook.com 2023-03-17T16:07:33.024Z 08DB26914934DDF9]”.”.

How can I solve this? version is Using V5.5.89 because error when I go to 5.5.94

2

After upgrade to version v5.5.89 from v5.6 The error message is gone but I don’t receive any email and also no errors. So can not trace if this is working now yes or no.

3

When back to version v5.5.63 but still same issues

4

I think the issue is microsoft removing legacy authentication?

5

That can be the case. But also google already left lecagy authentication. everything is going to modern authentication. So how can we solve this?

6

I even tried to disable the modern authentication (which is not my preferred solution) but even then it still won’t work.

7

Solved the issue. Will update later what i did. I was something in azure ad
