exclude attachment by file type

I am attempting to create a Flow that saves attachments from email to Onedrive - the basic template works just fine but I would like to save only attached files of a certain type i.e. only save the attachment if it is a PDF file. The issue I run into is that image files from users signature lines are saved as attachments along with the PDF file.


Accepted Solutions

I ended up creating 3 separate conditions for the 3 file types I want to capture.


I used the "File Name" contains and specified the ".pdf" and other extensions I want.


The condition states to "Create File" if the condition is met (File name contains the file extension) and Do Nothing if the conditions are not met.


It did require that I create 3 separate conditions, one for each file type.

Could you please attach a print screen so we have an idea how you set up the flow?





Not applicable

I added this condition in advanced mode :



contains(items('Apply_to_each_Attachment_on_the_email')?['Name'], '.doc'),

contains(items('Apply_to_each_Attachment_on_the_email')?['Name'], '.xls'),

contains(items('Apply_to_each_Attachment_on_the_email')?['Name'], '.ppt'))


without any blankspaces



I too am having difficulties only saving certain file types to SharePoint. I'm not sure where I would need to apply this particular condition for only PDF files to be saved automatically. Any assistance greatly appreciated.

If you want to save only PDF you should add :


@contains(items('Apply_to_each_Attachment_on_the_email')?['Name'], '.pdf')


in advanced mode between thoses actions "get mail" and "create file"

Bebe, many thanks not sure what I was doing wrong but after playing around a little more I've managed to get it working. 



@Anonymous Sorry to ask but you seem to know your way around Flow. Under the "if no" part of the condition I have setup an auto "reply to email" function however we are receiving multiple emails per email attachment on the email. Do you know a way of only sending one email if the condition is not met? I suspect the "apply to each attachment" part opf the rule is then applying the "if not" per attachment.

Don't know I'm new in Flow 🙂

I have the same issue. That for the negative condition it forward lots of forwards of the same email (in my flow if there are not pdf invoice then the rule is to forward that email to somewhere else). THen I realised it is due to the embeded images and some other stuffs part of the HTML emails. So in Flow it treat all those embeded stuffs as each attachment and run the condition for each.


Any one know how solve this issue. I only need pdf documents to passed to SharePoint and if there is not pdf document in the email then the email should be forwarded to a particular mailbox as it is.



Are you still using this approach? I'm a newbie to Flow and trying to understand your solution. I'm in a similar place, were the email signature image files, along with the email attachment are all being saved to the SFTP server. Tying to get rid of the images from the body of the HTML email.


If you, or anyone else who understands the solution, could post an image of how your solution works, I would greatly appreciate it.




Thank you so much.

It works for me.
