Hi Manuel,

Server-side rules are unsupported at this time. However, we have a task to address this in a future build. Client-side rules, on the other hand, should run automatically within Outlook, as of Build 8629 (Aug 17, 2023). If you're not already on this version, please update. 

If the update doesn't resolve the problem or if you're not sure whether you're using a client or server side rule, can you please share the details of the rule (omitting any personal data, as needed)? 

Thank you,

Hi Andrea,

Thanks for your reply, we are already using Build 8629 (ago 17, 2023) a few weeks ago.

Hi Manuel, 

This is a guide from Microsoft: 
Server-side vs. client-only rules

If it's client side, I believe it's indicated on the rule itself when creating or editing it. 

Please let me know what you find. 

Thank you for the update, Manuel!
