Is it possible to download attachments in outlook add-ins? I mean trigger 'save as' button by javascript. now I can get attachments by using item.attachments and then get base64 with
item.getAttachmentContentAsync
by this way i can download manually. But is it possible to make something like 'save as' calling?
I need something like item.attachments[0].saveAs('directory')
The Office JavaScript API (OfficeJS) doesn't provide anything for triggering built-in commands or saving attachments as a user to the disk. See Get attachments of an Outlook item from the server for more information.
