Office365 support incompetant - All emails marked as spam due to hyperlinks in email siganture
Hello all,
This thread has come to my attention. Let me fix some misconceptions:
Office 365 absolutely does scan messages "on the way out". This is done to protect our IP reputation. If a message is deemed spammy, then it will be marked as spam and sent out via a special pool of IPs. This pool of IPs has questionable reputation and we do not attempt to maintain their reputation. We do absolutely monitor the reputation of our good IP addresses - so much so that I'm fairly certain that is not an issue here.
Most often, I do see false positives happening when someone creates an automated email signature with links in them. A false positive requires a spam rule to be adjusted on our side. This is simple -
1) First report the problem in Submissions Explorer
2) If not getting headway, open a ticket - we just need the samples with the full headers showing what happened so that our engineering team can correct the rule. It is an easy fix - if you're not getting the help you need from the support, point them to this post as guidance.
I apologize for any inconvenience.
Regards,
Scott
MicrosoftMatRegan In addition to opening a support ticket, you should also be able to identify the specific URL and override it. But first and foremost, you should perform several submissions:

Thanks Scott Landry . We have raised a ticket with Microsoft and am working through the fault with them... but it is a slow process. We have had some success by removing incorrect hyperlinks from email signatures. It was as minor as changing our website address from www.mywebsite.com.au to http://mywebsite.com.au . Then the emails would pass through the server. I had tried to permit emails from our domain in the Outlook Admin but that didn't help (there's plenty of reports out there to show this doesn't work). I have also flagged the quarantined emails with Microsoft for review... that should keep them busy for an hour or two if they review them all individually. We'll see what tomorrow brings.
