Renaming Excel file when Saved in Sharepoint from Outlook

Hi All,


I tried the "Save my email attachments to a SharePoint document library" flow and it's running flawlessly. However, the Outlook attachment should overwrite the old file everytime it's received.


What is happening is the following:

-Original attachment name is abc-yyyy-mm-dd.xlsx, when it runs with the default flow I'm able to open it with Excel Online.

-Used flow to change the attachment name in the "Name" field to abc.xlsx, but Excel Online won't open this file.


What can I do to correct this situation?

Hi rogerabm,


It should be default for SharePoint library that when a file is created in the library, if it has the same name with the old file, the old file would be overwritten, if not, a new file would be created.


About what is happening on your side, I start the flow from the template, it works fine, I can check the Excel file with Excel Online.

Then I change the file name field to “import.xlsx”, run the flow with the same file as an attachment, the flow runs succeed, I can still check the Excel file with Excel Online.



Please try again with it on your side. If you are still having the issue, please feel free share a screenshot for the flow.


Best regards,

Hi Mabel, 


With this flow I'm able to open the attachment in Excel Online



But with this one it doesn't.


After further testing I also noticed it doesn't open on excel offline either and the file created is just a couple of kb's.


Hi @rogerabm,


I tried both of your approaches and it worked for me. The first screenshot below shows the Flow creating the file in the SharePoint library with the attachment's name and the second shows a custom file name I used.

HI @faustocapellanj 


Maybe you can help me


I have tried a lot to change the name of the email attachments it also works with different ways but all the time when I go to the file on SharePoint I get a mistake that the file can not be opened.




what i forgot to promise is that the new file name comes from the email body.


Hi @Snoop62

Are you trying to create a file using the email body as the file content?

I am facing similar issue. My flow runs successfully and creates file with "custom_name.xlsx" but when i go to SharePoint and try opening the file. it says "Couldn't open the workbook" neither with excel online nor on desktop. Could you assist with this please. Your help would be much appreciated.


Thanks !
