Outgoing emails marked as SPAM and Phishing emails by O365 servers
Hi, Since yesterday, all outgoing emails from our organization using Office365 (fully cloud) are being flagged as either spam or phishing email by Microsoft Outbound email servers. Due to this our...

Thank Jordan. We have several tickets open two of which have been escalated. We provided the link to this thread with no luck. We have ~30 hours into this client and MS support now.
Seems like your luck is better than ours lol. I will keep my fingers crossed that the description provided helps but it's pretty much what we already told them.
That really sucks, trying to get past the first line of support is the hardest.
As long as you have the headers stating the category, it should pretty straight forward to resolve. It's just trying to get someone from support who actually understands what needs to happen or have them escalate it to someone that knows.
I'm going to post this resolution to Reddit just-in-case MS decides to lock this thread or delete it.
It's a shame that support can't understand their own technology stack to identify and issue and provide some sort of resolution. This type of process resolution has been in place with other vendors like PaloAlto, Fortinet and Sophos for years.
MaxWinterstein I made that Reddit post. It's a shame Microsoft doesn't have a means to resolve the issue you're facing. When a organization get's so big, really difficult issues like this seem to slip through the cracks.
I've been through this now two times.
Every email containing my domain was marked as high confidence spam on every O365 tenant I know. On my own, as well as on customers. Even at the bare minimum, a plain text email containing just "myDomain.org" was marked as spam.
I knew about some spam incident involving our domain as an email sender from non O365 servers that fits around the starting time of the issue at the first occurence. For the second incident there is no realted event known to me.
Both times I have been hours in the Hotline with supportes that were honestly friendly and trying their best but tried everything to not move my ticket to second level support. They stick to their checklist and did not really take care of my mentions. E.g. he tried thousand times 'https://www.myDomain.org' at mail rules and stuff, even i showed him dozent times 'myDomain.org' was sufficinent.
Both times it seemed to resolve itself after roughly 7 days, which lets me think their internal filters drop after one week. Support guy told me that they were working hard on my ticket and someone fixed it...
After the supporter saw the issue resolved itself the ticket was closed. Definetly not satisfiying.
There is some panel the support guy pointed me towards: https://protection.office.com/reportsubmission where you can submit URLs that should not be marked as spam. If this is any good? Idk.
Not sure if this has already been posted here, but another good link I found about this:
https://www.reddit.com/r/Office365/comments/ev98sd/an_issue_with_a_microsoft_office_365_customers/
So i am sitting here, waiting for the next time this starts to happen...
EmailIssues
I'm having this issue with three of my personal MSFT email accounts, not through O365. I can receive emails but all my sent emails are being returned by the protection.outlook.com server. It won't even let me send an email to myself. Weird thing is that i can send emails from same accounts on my phone.
Any thoughts on who I can contact or do I just assume this is a bigger problem and hope it works itself out. Thank you.- Wow. this seems scary. you should not have had to go through all this before finally getting this fixed. Glad it all got figured out though.
- That's awesome!
Update: They finally did it!
Here is the text from MS if anyone needs it to point support in the right direction.
Hi ****,
Hope all is well. My name is *** from Office 365 Next Team,
We received an escalation request with regards to your issue on spam emails. After further investigation www[.]**********[.]com was listed as a phish URL, it appears the site may have at one time been compromised but is no longer. We have properly delisted it. Can you please check if your emails are still ending into spam/junk folder?
Thank you,***
Office 365 Next Team
