Emails being blocked by Gmail from office 365

Have also the same problem, Im using a @outlook.ph domain, Gmail blocked/rejected every messages I sent regardless whether I used app, web or mobile. The issue was started around mid March 2023.

The full text of the coming from postmaster is:

mx.google.com rejected your message to the following email addresses:

*** Email address is removed for privacy *** (*** Email address is removed for privacy ***)Your message couldn't be delivered because the recipient's email server (outside Office 365) suspected that your message was spam. To fix this, try to modify your message, or change how you're sending the message, using the guidance in this article: E-mailing Best Practices for Senders. Then resend your message. If you continue to experience the problem, contact the recipient by some other means (by phone, for example) and ask them to ask their email admin to add your email address or your domain name (the text after the "@" symbol in your email address) to their allowed senders list.

For Email Admins
When Office 365 tried to send the message to the next email server outside of Office 365 the external email server returned the error below. This indicates the recipient's email server (or their email filtering service) suspected the sender's message is spam. If the sender isn't able to fix the problem by modifying their message then contact the recipient's email admin and ask them to add your domain name, or the sender's email address, to their list of allowed senders.

While the sender may be able to alter the message contents to fix this, it's likely that only the recipient's email admin can fix this problem. Unfortunately, Office 365 support is unlikely to be able to help fix these kinds of externally reported errors.

mx.google.com gave this error:Remote server returned message detected as spam -> 550 5.7.1 [2a01:111:f403:7005::802 19] Our system has detected that this;message is likely suspicious due to the very low reputation of the;sending domain.

I've tested so many ways, this is the only working solution so far.

Thank you so much.

Can you provide detalles instructions for those of us that have no idea how to do what you did? My knowledge goes as far as adding DNS to the domain if I know exactly what to add

Sorry if it is to much to ask

How about all other domains?

Do we have option to enforce exchange not to use IPV6 email delivery??

Just notice the email was marked as spam. Any way that can enhance the records?
