This SPFx Outlook Add-In lets users save any email attachments to a One Drive folder. The users can select any One Drive folder/subfolder and choose the attachments that need to be saved. It uses Microsoft Graph API to fetch the One Drive folders and upload the attachment files.
This web part illustrates the below features for creating Outlook Add-Ins using SPFx.
