Hi,

I used a template to save attachments when an e-mail arrives to an specific folder in OneDrive, so far that works, but files are corrupted, doesn't matter the type (pdf, excel file, jpg, etc.).

Here is the code.

{

  "type": "OpenApiConnection",

  "inputs": {

    "parameters": {

      "folderPath": "/",

      "name": "@items('Apply_to_each_attachment_from_specific_user')?['name']",

      "body": "@items('Apply_to_each_attachment_from_specific_user')?['contentBytes']"

    },

    "host": {

      "apiId": "/providers/Microsoft.PowerApps/apis/shared_onedriveforbusiness",

      "connection": "shared_onedriveforbusiness",

      "operationId": "CreateFile"

    }

  },

  "runtimeConfiguration": {

    "contentTransfer": {

      "transferMode": "Chunked"

    }

  },

  "metadata": {

    "operationMetadataId": "3c78f01d-b520-47ef-872b-acad8fdcccb6"

  }

}

Can somebody help me, please.

Hi,

The most likely root cause are the settings in the trigger. Make sure these are both set to Yes. I will also share one of the most important things about this flow: RESUBMITTING test runs will not correctly save your attachment content!!! I have learned from experience that in order to retest your flows with attachments, you need to send a new email. That means that maybe your flow is already setup correctly but you are resubmitting previous test runs and finding those attachments are not readable.

Then in the create file action, make sure you point to the contentBytes in your trigger.

Always glad to help! 💯💯💯💯💯

I have a flow almost exactly like this. After the On new email action, I test a condition, branch, then on either branch I create a One Drive file.

The one difference is that, inside both of the For Each Attachment loops, I added the Outlook action Get Attachment (v2) immediately before the OneDrive Create file action. Then pull the dynamic values for Name and ContentBytes from the Get Attachment action -- NOT the On Mail trigger action.

Before I added that action, I had the same results as you. Adding this extra action, the attachment saves correctly. I've found this in a few places in Power Automate: the trigger action alone seems like it should provide all the info...but it just doesn't.

Let me know if this works for you.

Stew

Hi

Have you looked at the contents of the Files? is it string / 8 / 64 base anything?

I am wondering if you are actually writing the improper contents
