Manipulate filename from email attachment

I used the SharePoint create file action to save file to SharePoint library from email attachments. It overwrites the file if it already exist. I then try to add with timestamp to the filename but only as prefix because the "Name" dynamic content from email attachment includes file extension. Ideally, the new filename should be [filename]-[timestamp].[file extension]


I am still new to use Flow. Anyone has suggestion or work around for this? Thank you.


Great tutorial. I'm getting this error message: 

The template validation failed: 'The action(s) 'Compose-GetFileName, Compose-GetFileExtension' referenced by 'inputs' in action 'Compose_3' are not defined in the template.'.
Ring any bells?

HI @pagemian 

That means that the name of your actions do not match the names of the actions in the walkthrough. Here's what you can do:

  • You can update the expressions to use the name of your Compose_3 action
  • Or you can rename your Compose actions to match the names I'm using: Compose-GetFileName and Compose-GetFileExtension.

Once you do any of the above, your Flow should be fine. Please do not hesitate to reach out if you have any questions or issues.

Worked like a charm! Thank you. What I'd really like to do is have the file name be the subject line of the incoming email. Any thoughts? I've removed the Compose-Timestamp function so far.

Nevermind! Changed the input for get filename to email subject. DONE! Thanks again!

Hi @pagemian 


Glad you got it working 😀

thank you for this flow works perfectly. 

I was wondering how can I put a condition to exclude certain file types such as .png or jpg as the signature images are also getting captured in this flow?
