Exchange Transport Rule Remove SharePoint Links
Hey everyone, So we recently implemented an Exchange online (M365) transport rule to add a small amount of HTML text at the top of the email, warning the email has come from an outside source, however this appears to have caused an issue with sharePoint links sent from external parties. The image etc are all there, and all the links to Microsoft.com etc are all fine, however the image for the excel/ word doc etc, are now just blank images, without the URL behind. If you remove the transport rule its all fine. The HTML on the transport rule is this <!-- Red Banner --> <table align="left" border="0" cellpadding="0" cellspacing="0" style="width:100%"> <tbody> <tr> <td style="background-color:#ec6137; width:4px"> </td> <td style="width:1187px"> <p><strong> Caution:</strong> This email originated outside of the *******. Be careful of attachments and links. Report suspicious emails to ServiceDesk.</p> </td> </tr> </tbody> </table> <p> </p> There's nothing in there to strip the attachments, but the email is being modified by the HTML warning, so its plausible to see with Exchange would see it as a threat. We do have the safe senders part of Exchange turned on etc. Any thoughts? Ta
How to inject disclaimer of "From"-Mail when Sender is different with a Mail-Flow-Rule
Hey guys, I'm currently trying to define a Mail-Flow-Rule which checks whether an E-Mail was sent from someone who has the permission to write a mail as a delegate. E.g.: We have two users: Chief and Sub Sub is a substitute of Chief Sub writes an E-Mail for Chief => The E-Mail header "From" is Sub while the "Sender" Header is Chief The check works fine, but I cannot include specific AD Properties from Chief into the Mail. When using for example %%Email%%, the Mail-Adress from Sub is injected into the disclaimer. My questions: - Is there a way to get specific Informations about Chief? - Is there another feature aside from "Mail Flow Rules" which allows this?
Exchange 2016 Transport Rule for Empty/Blank messages
Hi, I am trying to configure a transport rule in Exchange 2016 to identify email messages that are (almost) empty. We have been receiving these messages lately and my attempts to identify them have failed. My Transport Rule is also failing. Any ideas would be appreciated. Cheers, Timotatty
