Re: Stop Teams from pinning my message
Ryan SteeleThis same issue has been plaguing me of late. I go to the menu to select "Edit," and just as I select Edit, the menu expands. Consequently, I end up selecting "Pin," and now I have to undo the pinned message. It would be great of that menu in Teams was updated much more quickly than it is.16KViews6likes0CommentsRe: Using a 3rd Party Email Gateway to Insert X-MS-Exchange-Organization Headers
VasilMichev I was able to create two ETRs to add the headers I need, however, interestingly enough, I cannot see the headers in the actual delivered message. This is in spite of the message trace showing the Transport rule firing to set the header. I will likely remove the SCL setting from these rules, as it is not required.6.2KViews0likes2CommentsRe: Using a 3rd Party Email Gateway to Insert X-MS-Exchange-Organization Headers
VasilMichev The behavior makes perfect sense. I was trying to avoid employing a transport rule and move the processing upstream. I am going to test it via a transport rule instead, now that I remembered how to have a rule fire on a specific header value.6.2KViews0likes0CommentsUsing a 3rd Party Email Gateway to Insert X-MS-Exchange-Organization Headers
I wanted to post to confirm a suspicion I have, as I cannot find any solid source of this information elsewhere. Does Exchange Online "strip" or "firewall" the message header of some X-MS-Exchange-Organization if they are present in an inbound message received from an external sender? I am using a mail gateway to add two custom headers (X-MS-Exchange-Organization-SkipSafeLinksProcessing andX-MS-Exchange-Organization-SkipSafeAttachmentProcessing) to bypass the application ATP protections to emails originating from our phishing education tool. I can see the headers being added to the message at the mail gateway, but they are not present on the received message in Exchange Online. This leads me to believe that Exchange Online is stripping these headers out. Confirmation of this behavior is appreciated! Thanks!Solved6.3KViews0likes5CommentsRe: Random MFA prompts from Universal Store Native Client
I want to chime in on this thread, as we are seeing the same behavior. (Unfortunately, our MFA configuration is not CA-based, as we have not altered it from turning it up almost 2 years ago and "forcing" MFA for everything.) The good part, as others mentioned, is that users are reporting an unknown authentication attempt as fraud. The bad news is the user has no idea what is triggering it, and the logs point to the Universal Store Native Client. I look forward to possible solutions.28KViews0likes0Comments
