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
Just thought I'd post on here, even though its pretty old, that we just ran into this issue 5 days ago and Microsoft is still completely useless.
To recap:
1) All outgoing mail with a hyperlink (including mailto:x@x.com) gets marked as spam. Doesn't matter if its in a signature, body, etc... just any hyperlink period. You can see this in a message trace as it shows the mail going out getting tagged with a spam event and to 'Use high risk delivery pool.'. Attachments and embedded pictures are fine as long as they're not linked. An easy way around this is to set everyones default new mail format to plain text instead of html. I should add however that this didnt happen EVERY time, just 99% of the time. Which was great for Microsoft troubleshooting because as soon as they saw one work without being marked as spam, they said it wasn't their system.
2) We initially noticed this problem due to a massive increase in good inbound mail going to junk e-mail. At that time we also found that whitelisting the domains or email addresses, in the O365 exchange admin page, did nothing, they still went to junk. We had to make an actual transport rule to allow the domains.
3) We found that external mail to externally accessible Public Folders was all being rejected with the message '550 5.4.1 All recipient addresses rejected : Access denied'. I checked the permissions in case they changed, nope - anon still has contribute and create items.
4) If enough mail gets sent out by an internal user, MS will block them and, in our case, when its false, it takes over an hour for the unblock to actually take affect. So I have Customer Service Reps that can't actually send mail to get orders placed for an hour.
I've searched for hours trying to find a way to get better support. Give me back the days when I could slap down a credit card and charge a single premier ticket.
TRI-JAI can totally relate to your issue. MS is totally clueless about this behavior and passes the buck onto someone one stating that we do not mark emails as spam. I would strongly suggest you use the Message Analyzer tool to identify the IP add of all outgoing servers and check if any of them have been blacklisted on the Internet.
