Create File Corrupting

Hi All,

 

I have a flow which collects an email attachment and saves it as a new file in our SharePoint. 

Chrisss14_0-1676565359056.png

When I then go to the SharePoint location, it says the "File format or extension is not valid". The files are only Excel files and I specify which type as shown below. Am I missing something?

Hey Ellis,

 

Thanks for the above. The workaround didn't actually work for me but in the end I found my own. It seems to be an issue when creating a file and directly asking it to be created into a SharePoint document library. 

 

I created a new folder within the questioned document library, pointed the file creation step in automate to the folder (rather than just the doc library itself) and then ran a test. This then allowed me to open the files fine without corruption. It's been running for the last few days and all documents can be opened fine. Is a bizarre issue!

Hi @Chrisss14 ,

 

Hmmm... This is a question that I'm starting to see more often than I would like.

 

Please see if the following workaround fixes your issue FIX: Corrupt or Bad File when trying to open a file that was saved to SharePoint using Power Automat...

 

A workaround I have found for this issue is to manually specify the file content type and content:

In this context, or similar I want to save an outlook message to SharePoint. 
What would be the content type of an .msg file, an outlook message?

Hi @MichelH ,

 

In this case you would need export the email, then use this output as the content for your file.

 

For an example, please see: Re: Adding an email itself as an attachment to Sha... - Power Platform Community (microsoft.com)

@ekarim2020
Thank you for your response Ellis,   

I understand that part, but I have run into situations where in fact a text file was created with the base64 content of the file I wanted to create. It presented itself with a .pdf extension, but it was not a pdf file.

I thought using the compose to create a combination of content and content-type might help to avoid this. 

But I also see that many people state that you cannot actually save .msg files using power automate, but only .eml files. These are very different file types, where  .msg files are binary files and .eml is text.

 

Br,
Michel

Unfortunately, the Export email (V2) action will only "Export the content of the email in the EML file format."

Hello @ekarim2020 

I am having a similar problem and found this post when I was looking for a solution. 

I receive an email which has an attachment that I want to save on SharePoint with the file name as the subject. The file would not save correctly (showed as corrupted file) so I used your suggestion of using Compose. However it is asking for a valid Json. I do not see anything on your comment, am I missing something? Can you help me resolve this?

Hi @sshet ,

 

You forgot to add a comma between the properties:

Hi @ekarim2020 ,

 

Thanks for spotting the missing comma. I am still having trouble with the file's content and type. I set up the flow using the workaround you mentioned on the link you provided. But the workaround did not work for me. You might notice that I have added ">xlsx" after Subject as the File name. I tried it with and without the .xlsx, the result is the same. I think the issue is with the content transfer, and not the format.

 

This is the error I get:

The Flow:

Hi  @sshet ,

 

Add a condition that checks if the attachment is an Excel file before saving to SharePoint. We can do this by checking to see if the attachment name ends with xlsx (or .xlsx):

If you still have problems, please share your flow.
