I am trying to get Email attachment from Dynamics CRM and want to save the file in its original format.
When I try to get information from CRM Email entity I am getting a base64 string as the content of the attachment. I don’t know if it is jpg or png or pdf or txt or any other file format, now how can I convert it to its original file format.
Can we identify the format of the file from base64 string itself or we need to have other information to know the file type ??

I tried getting the the ‘activitymimeattachments’ entity from CRM through postman and I am getting base64 string. Now I want to save whatever this attachment is in its original file format. How can I do that maybe using ADF or Logic Apps
