me.mailFolder

Create mailFolder

Changed on Jul 17, 2026

Use this API to create a new mail folder in the root folder of the user's mailbox. If you intend a new folder to be hidden, you must set the isHidden property to true on creation. To create a mail search folder, set the '@odata.type' property to '#microsoft.graph.mailSearchFolder' and include the filterQuery and sourceFolderIds properties.
