Failed to send email with shared mailbox

(0) ShareShare
ReportReport
Posted on by Matt Smith - Cha Ltd 65

Good morning,

I have connected a shared mailbox within Business Central, it seems to send test emails fine. When we try and send an email to a customer (with invoice attached) the below error is received:

Could not get access token. Please, try to log out and log in again.

Has anyone come across this error and knows of a way to fix? It was working fine, but has suddenly stopped working with no change. All users have 'send as' permission in exchange and are members of the shared mailbox.

Regards,

Matt

    Hello,

    It could be that the token got expired. Is there anything specific to be found in the application event log file assuming you are working with the OnPrem v17 release?

    Thanks.

    If this happens only when a system code unit sends an email such as in approval then each end user should use test email function and validate access. After validating once then system emails will function.  Assuming MFA is setup and O365 accounts are used instead of SMTP

    I would recommend that for EACH and EVERY user that gets this error, they go to the Email Accounts page, select their account and use the "Send Test Email" action.

    This will refresh the TOKEN for them, and the message should be gone.

    Assuming O365 accounts are used instead of SMTP and you have valid licenses for those users.
