Rocky,

Do you want the actual file attached to the task to be in Asana or as a reference to the file (link) and store the file elsewhere like google Drive?

For the first, there is an API to attach the file into Asana: https://developers.asana.com/docs/upload-an-attachment

For the second, save the email to a cloud location (like google drive) the add the file reference to the task in asana.

Thank you for your reply, I was looking to include the Outlook attachment as an attachment on the Asana task, photo, pdf etc.

@RockyvN unfortunately, the API for “Upload an attachment” to a task requires you to download the file content first and then upload it as any other attachment. (see https://developers.asana.com/docs/upload-an-attachment).

Further it is not possible to attach files from third party services such as Dropbox, Box & Google Drive via this API.

I recommend the approach of saving the file to a cloud storage (e.g. google drive) and place a reference to the file in the task.
