Using classic Outlook for Windows in business environments
Hi @Mark Grahne
Based on my research, Outlook inbox rules can be categorized into client-side rules and server-side rules.
This distinction may explain why certain inbox rules are visible in Classic Outlook but do not appear in Outlook on the web (OWA). Some rule conditions and actions are only supported in the Classic Outlook desktop application and cannot be synchronized or displayed in OWA.
For example, there are specific conditions and actions that are available exclusively in Classic Outlook, which may cause those rules to be hidden or unmanaged when accessing the mailbox through OWA.
For reference, please see: Edit or fix a broken rule in Outlook - Microsoft Support
With that in mind, could you please help confirm whether the rule you want to manage in OWA falls under any of the rule conditions or actions mentioned in the examples above?
If I’ve misunderstood any part of your situation, or if you have further questions or updates, please don’t hesitate to reply.
Thank you for your time, and I look forward to hearing from you soon.
