In the first instance, check the named user has an email address in their user record in System, Security, Users. If this is not populated then update the record with the correct email address.
If the user's email is in place, or updating it does not solve the problem - our support team will need to investigate, run scripts or liaise with the hosting or development teams. Any Issues with contacting us, please see the following Get support in Financial Operations.
This fix also applies to the related error 'Could Not Determine Recipient Address'. Both errors share the same root cause: the recipient of an approval notification does not have an email address on their FinOps user record.
If updating the email does not resolve the issue
If the user's email address is correctly set in System, Security, Users but the error persists, the email may not have synchronised to the FinOps user record. Contact the support team and provide the name of the affected user and the form or approval stage where the error occurs.
