Cannot drag and drop documents nor paste into "Combine files into a single PDF" in Acrobat

Hello,

I have a user who needs to drag and drop several PDFs from Outlook and combine them into a PDF using this feature. Instead they get a stop symbol. They also cannot paste from their clipboard.

I am experiencing it on my copy of Acrobat also to verify. I have already ran a repair and restarted their machine. We are updated to the latest version of Acrobat which is 25.001.20756, and on Windows 11 25H2. We are also using the NetDocs ndAdobe integration.

Please advise, thank you.

@katie_4800 it's likely a security issue. Honestly, I would save the PDFs to the computer first. Once saved, drag and drop the files from the local folder into the "Combine Files" window, or use the "Add Files..." button within Acrobat.

This worked for her. Thank you!
