Hello,

Im trying to make a flow wich looks into my email and when i receive an email with attachment pdf it will send it to onedrive, and from there i want to to extract text from it.
If i upload the pdf manually to onedrive the flow detects the file and extracts the needed information for me.

But when i send an email and it saves to onedrive whatever i try to do the file is corrupted or blank, so it somehow changed the pdf so i cant use it anymore, does anyone know a solution for this?.

Edit: i have to mention that the pdf file contains an png, (still when i upload manually it works, through email the file gets corrupted)

Hi

Please try the following:

Then see: Power Automate: Formatting File Attachment Arrays for Approvals, Outlook, OneDrive and SharePoint – Ellis Karim's Blog, using the following format for the email attachment:

See also: Office 365 Outlook - Connectors | Microsoft Learn: "In some cases when using Send an email V2 to send multiple attachments, the resulting files may be invalid. In those cases it is best to follow the below process as a workaround."

is it possible to share a working flow wich can detect pdf files in an outlook and sending them to onedrive, and see if i can use the flow?.

i had a it specialist from my work looking at it and also he couldnt manage to do it.
than he said he could use other pdf files that where working, but for me they didnt.. while we have the same flow.... i dont understand
