Email Account from another Microsoft tenant

(0) ShareShare
ReportReport
Posted on by 337

Hi everyone, 

We are trying to add a new email account in Business Central using Office365 server settings and the credentials of an account that resides in another Microsoft tenant (i.e. BC runs on tenant A and the account is created in tenant B). The account has an Office 365 E5 license. 

When we try to send a test email from BC, we get the below error;

We tried using both Basic and OAuth2.0 authentication. SMTP Auth is switched on in the mailbox as per below;

When adding the account in BC we choose SMTP , and input the below details. As previously mentioned, we tried both Basic and OAuth2.0.

Any suggestions as to why this is not working, please?

    It is possible that your account may not be subscribed to Office 365, can be the reason why you are facing issues with SMTP settings

    Hi, try setting the email in your contact email, in smpt set your email as the default email address for the current user

    and set the same email in your SMTP setting

    Hi, just tried the above but still does not work. A personal outlook account as the one you have in your screenshot works but it is being suspended for suspicious activity every now and then since an external app , in this case business central, is sending emails using that account.

    In my scenario I am not trying to add a personal account (that ends with @outlook.com) but an email account on a microsoft tenant.

    Hi Y_A,

    Make sure that you have entered the correct email address in both the "Email Address" and "User Name" fields

    If it still doesn't solve then try selecting the current user instead of the specific user and add the same email address in the user contact email field.
