554+5.2.0+STOREDRV.Submission.Exception:SendAsDeniedException in IIS SMTP Relay When Scanning to Email from a Sharp MX-M364N

I found I the Sender Name: value MUST be set under System Settings -> Image Send Settings -> Scan Settings.

If Sender Name: value is blank the email will not send and you will receive the above mentioned error in your SMTP logs.

I had almost same issue, solved it by adding Send-As permission to the sender account. but if youre using Alias (not account) then add the Alias to the mail account. Somewhere in July-october 2018 Microsoft changed this.

i have this setup: Application sends mail to (as [email protected]) -> postfix -> Postfix relays to Office365 with account ([email protected]) to the Customer. but this kept failing with the error "Submission.Exception:SendAsDeniedException.MapiExceptionSendAsDenied"

after i added [email protected] as Send-As permission on [email protected] mailaccount, then my problem were solved.

hope this info helps.
