How to Save PDF Email Attachments to OneDrive for Business Using Power Automate

You can use Power Automate to automatically move your email attachments to a folder in OneDrive for Business. In this post I’ll show you how to move PDF (or any other file type) attachments to a OneDrive for Business folder.

This is the flow that we will build:

1. Start by creating an automated cloud flow:

2. Give your flow a name then select the flow’s trigger as When a new email arrives (V3):

3. Set the following two properties of the When a new email arrives (V3) trigger:

4. Add an Apply to each loop (2) and set Attachments as the output (3) as shown below. The loop will save each attachment to a OneDrive folder of our choice:

5. Add a Condition to check the attachment’s filename (4). We want to check if the attachment name ends with ‘pdf’. If the attachment name ends with ‘pdf’ we want to save it to our OneDrive folder. Change the condition to save other file types.

6. Add a OneDrive for Business Create File action (5), then select a OneDrive folder to save the attachments to. In the example below I am saving the attachments to a folder called Attachments:

7. Finally select the attachment’s filename and file content Dynamic content:

Saving different File Types

Notes

When a new email arrives (V3) – This operation triggers a flow when a new email arrives. It will skip any email that has a total message size greater than the limit put by your Exchange Admin or 50 MB, whichever is less. It may also skip protected emails and emails with invalid body or attachments.
