Hello,

I’m having an issue with a fairly simple automation, and I’m not sure what’s going wrong.

I want an email account to identify a tag in the email's subject line upon receiving a message. Up to this point, everything works fine.

Afterwards, for each message identified with the correct tag, I want to save the attachments to OneDrive only if they are .docx, .doc, .xlsx, .xls, or .pdf files.

When I run a test of my flow, the automation detect the attachments, but it doesn’t recognize any of them as ending in .pdf or .docx (for the test).

The flow :

i don't understand where is the problem ...

Kind regards

In your condition you have swapped the order of the field and the value. Like you mentioned, you want to check if the Name ends with .doc.

Please place the Name field on the left side and the '.doc' text on the right side.

Here are high level steps:

Trigger: When an email is received.

Condition: Check for the tag in the subject line.

Action: Use the Apply to Each action to loop through all attachments.

Condition Inside the Loop: Check the file extension using endsWith() and toLower().

Action: Save the attachment to OneDrive if the file type matches the allowed extensions.
