From my view it looks that it's sender's email server which is in trouble but sender isĬonvincing that they don't have any issues with their email servers.Īdditionally question is that are we able to disable all spamfiltering from O365 in cases where we are using 3rd party spam filter and we would like make our environment simplier.ĭelivery has failed to these recipients or groups: We have also understood that he doesn't have other issues with his emails. Exchange 2010 was always able to get his messages. Now there is least one sender who is not able to get his message to Office365. Earlier Exchange 2010 environment was in place. Nonetheless, if you could point me to the extensive documentation which explains the combined workflow of all involved parties (server, client, forefront, microsoft clearing center, etc.) that would be great.I have implemented Office365 environment to our customer. Your nutshell confirmed most of my suspicions. and variations of those.įor me as an admin for several customers with different levels of understanding the IT world, it's a challenge to be able to explain users why a certain message was junked or not. The questions I am faced with are always alike: Why was message X put in Spam folder? Why was message Y not put in quarantaine?. I have yet to find a documentation which describes the overall approach on AntiSpam/Anti-whatever with all the Tools and possibilities of the Microsoft Portfolio. There is a lot of information to read on this matter, but it's Is something similar happening when a user mark a message as "Not Junk" in his Outlook 2016 junk folder? Or is that something totally local and user based? I would be interested in the details of that process. What exactly is Microsoft doing with these messages? I would suppose they analyse it and feed the results somehow into the algorythm which "finds" spam in the future. The explanation in the message tells us that this option will report this message as not junk to Microsoft.

There is also an option like "Report as not Junk" or similar. Moreover, when I use quarantine in the Exchange Server Spam filter settings, with user notification, the user receives regularily an email where he can release a message from the quarantine into his inbox. If the Office 365 spam filter settings deliver junk/spam to the junk-mail folder, and Outlook 2016 does the same, the result is emails in the junk-mail folder that origin from two different mechanisms.What happpens when a user selects a message in the Outlook 2016 Junk-Mail folder and defines it as "not Junk"?.Is that kept local in his profile? Is this blocking "shared" with the Exchange server in Office 365?
