Ever since we have moved from Office 2010 to Office 365, random users are receiving NDR and we haven`t been able to find the root cause of it.

It happens for random users once or twice a week and message trace doesn`t show anything as it fails instantly on sending the email. It could be to internet or external user.

Diagnostic Information:
Error is [0x80070057-0x00000000-0x00000000].
Failed to upload attachments to server (error 0x80070057).
Submit-Message failed: message id(8), failure enum(29), HResult(0x80070057), EC(0).

When you forward the error as an attachment, it contains the following information.

Diagnostic information Generating server: /o=ExchangeLabs/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=141b278332c64dc1a9cbb0b5d158ea5c-
Remote Server returned '554 5.4.0'

Outlook Version 2108 (Build 14326.20910 Click-to-Run)
Semi-Annual Enterprise Channel

We have tried recreating profile for the user. The temporary work around is to recreate the email, the same email from sent items fail with the NDR each time.

Any suggestions what could be causing these NDRs intermittently?

    Hi @MXJ ,

    Welcome to our forum!

    According to your description, I notice your Outlook 365 version is not the latest. Please first make sure you have upgraded your Outlook to the latest version.

    Based on my research on the error "554 5.4.0", I found that it may be related to with too many hops. It's suggested that you could refer to this thread: Remote Server returned '554 5.4.0'.
