Exchange rule issue with "Prepend the subject of the message with"
Dear all, I am encountering an issue that I have been unable to resolve despite researching extensively online. Contextually, I need to forward all incoming emails from a distribution list to a shared mailbox. To identify these forwarded emails in the shared mailbox, I attempted to add a text to the subject line (namely, "The DL should no longer be used by my colleagues in a few months"). Here's what I've done so far: Condition: "Recipient", "Address matches any of these patterns" (I've also tried "The sender address includes") Actions: "Add the recipient:" "to the Cc Box" => my shared mailbox "Prepend the subject of the message with" The forwarding is working as expected, but the subject line is not being prepended with the chosen text. Have I missed something? Thank you all in advance for your help. Best regards, Guillaume
DLP Rule for Exchange using ExceptIfRecipientDomainIs not working any more
Hello, we had setup a DLP Rule for Exchange workloads that only allows sending to specific external recipients in a list we provide via populating the ExceptIfRecipientDomainIs attribute. This has been working fine until a few days back, when suddenly the rule was failing to apply on end users (domain is listed in the Rule's ExceptIfRecipientDomainIs) and email gets blocked. I then realized that the attribute is not populated anymore via Powershell and comes back empty! (Get-DlpComplianceRule -Identity "DLPRULE").ExceptIfRecipientDomainIs At the same time, the Rule on the compliance.microsoft.com portal shows up properly with the domains in question. I then noticed that those domains now only appear under the AdvancedRule attribute only. (Get-DlpComplianceRule -Identity "DLPRULE") | select -expand advancedrule So it seems there has been some change in DLP rules by the compliance team at Microsoft?
