Note emails to standard M365 tenants all work 100% fine, DKIM is always a PASS. It seems like Outlook for MacOS is doing something to the message header that and email servers don't like.
MICROSOFT OUTLOOK MAC HEADER DEFECT WINDOWS 10
What is VERY interesting and why i claim there is a bug in the Outlook for MacOS app, is that if I then send an email from from a Windows 10 machine with latest Office365 apps installed, and send an email from Outlook 365 App for Windows, DKIM passes for example: I am striving for 100% SPF, DKIM and hence DMARC performance across all the domains i manage. Smtp.mailfrom=sjsthxx**** dkim=pass (signature was verified) header.d=sjsthxx**** dmarc=pass action=none om=sjsthxx**** compauth=pass reason=100 If i then log into the webmail interface for the 3 domains and send a test message to *** Email address is removed for privacy *** and *** Email address is removed for privacy ***, the DKIM check passes no problem for example: This happens for all 3 domains WHEN using Outlook for MacOS to send the email. Smtp.mailfrom=sjsthxx**** dkim=fail (signature did not verify) header.d=sjsthxx**** dmarc=pass action=none om=sjsthxx**** compauth=pass reason=100

If the response is helpful, please click " Accept Answer" and upvote it. If the issue still exists on those specific messages, I think it may also be related to the messages themselves, have you checked if there are any similarities on them(such as from specific sender or other similarities), if it possible, please try to reply them in your web mail to check if it could work normally there. If so, based on my tests on Outlook 365 version 2106(version 14131.20332), I could reply messages with those information normally, so in the point of your client, what's the specific version of your Outlook desktop client(File>Office account>About Outlook), please first ensure that you have updated to the latest version of Outlook.Īs I know, if we set "when replying a message do not include orginal message" in Outlook, it may not display any information about your original messages, please kindly check it and keep this setting in Outlook when you forward/reply the message.Īfter that, considering some third-party add-ins may also cause it, it's recommended to reply on safe mode for testing( Windows + R > type "Outlook.exe /safe">enter) Hi you mean that you lose these information below when you reply/forward some messges in Outlook?
