Since this is a specialized backend issue within a Dynamics product, seeking help from dedicated Business Central specialists is the most effective approach.
Business Central handles complex ERP scenarios that fall outside general Microsoft 365 troubleshooting. The Microsoft Dynamics CRM and Business Central forums are actively monitored by product specialists who can investigate tenant-specific email configuration bugs.
Open your web browser and go to the official Microsoft Dynamics Community portal.
Click on the Business Central forum or Dynamics CRM forum depending on your specific product integration.
Create a new thread describing the 'email account does not exist' error, making sure to include your Business Central version and whether you are using SMTP or Microsoft 365 email integration.

Verify Email Account and Scenario Setup in Business Central
Check if the default email account is correctly authenticated and properly mapped to the journal posting scenario.
Boost Your Productivity with WPS Office

WPS Office offers a highly compatible, cost-effective alternative to Microsoft Office for managing all your exported Business Central data.

Frequently Asked Questions
Why does Business Central need an email account to post an item journal?
Business Central may be configured to automatically send email notifications, workflows, or reports when an item journal is posted. If the system attempts to trigger this email but the linked account is missing or improperly configured, the posting process is halted with an error.
How do I set a default email account in Dynamics 365 Business Central?
Use the 'Tell Me' search feature to find 'Email Accounts'. Select the account you wish to use from the list, and then click the 'Set as Default' action in the top menu ribbon.
Can I use a shared Microsoft 365 mailbox for Business Central automated emails?
Yes, you can configure a Microsoft 365 shared mailbox in the Email Accounts setup. Ensure that the user authenticating the setup has 'Send As' or 'Send on Behalf' permissions for that shared mailbox in Exchange Admin Center.
What if my email account is correctly set up but I still receive the missing account error?
Check the 'Email Scenario Setup' page. It is possible that the specific automated action (such as posting) is hardcoded or assigned to a deprecated email account instead of the current default account. Reassigning the scenario should clear the error.
