Is it possible to add a custom context menu to a folder in Outlook?

Dear @Mavillapalli, Venkateswara,

Thank you for posting your question in the Microsoft Q&A forum.

I understand your query about adding a custom context menu to a folder in Outlook. I totally agree and understand how important it is to streamline workflows and provide users with quick access to business logic configuration.

Currently, Outlook’s extensibility model is primarily designed for message and appointment surfaces (e.g., reading or composing emails), not for folder-level context menus.

While it is technically possible to extend Outlook functionality using the Office Add-in model, implementing a custom context menu for folders is a specialized scenario that requires development and testing. Unfortunately, as community moderators, we don’t have the resources to fully validate or support this implementation here. As frontline support staff, I am just organizing use cases and collecting data, including from you, on a daily basis and will continue to monitor the progress of this case.

Therefore, the most efficient and reliable next step is to contact Microsoft Support or refer to the official Microsoft 365 Developer documentation for guidance on supported scenarios and best practices:. They can confirm whether folder-level context menu customization is supported and guide you through the correct approach. Here are some helpful links:

I hope this information is helpful. Please follow these steps and let me know if it works for you. If not, we can work together to resolve this.

Thank you for your patience and your understanding. If you have any questions, please feel free to reach out.

I'm looking forward for your reply.
