Hello Ron Margalit,

Thanks for post in Microsoft community. Generally when we create, edit, enable/disable rule from Microsoft365 Admin center, it will take some time to sync with server. So if you just did this activity, suggest you to kindly wait for couple of hours and then check the result. If already it spend many hours, please check below suggestion.

Sometimes, you might set up several rules that could apply to a single message and if on the first rule, if you had set the option stop processing more rules then subsequent rules will be ignored, even if they apply to the message. So given this situation, if you have set up several rules in your organization, please check if any rule is set as stop processing more rule option. If yes, you can disable it, so every rule that applies to the message will run.

To check this information, we suggest you to kindly run message trace report for the specified email and once report generated, open it and check the details. Message trace report will help us to identify if other rule is causing issue or not. To run message trace, you need to contact your Microsoft365 Admin and if you have admin rights, please follow the below steps and check.

• To do so: Login with Global Admin account in Microsoft 365-> Exchange admin center -> Mail Flow -> Message trace -> add the sender, recipient email is and select the date range (once message trace report open, select the trace, open it and share the detail information with expand each information)
• For your reference, please check Run a message trace in the classic EAC.

Also kindly share message trace detail report and your created Transport rule’s screenshot to us via Private Message, so we can also help you to check the issue indeed.

Besides this for your affected rule, you may also try with set lower priority as “0” to check if it helps. For details, please check

Set the priority of a mail flow rule.

For your privacy, we will send you private message for collecting it. Please let us know the above details Private Message, so that we can help you investigate to it further.

Thanks and Regards,
