Hey, So we have a bit of an odd issue here. We map OneDrive & SharePoint libraries (cloud storage) via a network drive letter on Windows computers via a technology called WebDav. A client called and said when password protecting a PDF document and saving it, then going to Outlook and attaching the file from the "Recent files" list - the document will attach, if you then open the file preview when in the draft email the document opens in Adobe Reader and doesn't ask for a password. If you attach it via browsing the computer directory, going into the network drive then attaching the PDF, when opening it this way it asks for a password. It's like a strange Adobe Reader cache and bypassing it somehow in Outlook. Has anyone ever come across this or similar behaviour? Running Adobe Acrobat Reader 2022.003.20282 32bit Microsoft 365 Apps for enterprise Version 2211 Build 15831.20190 64bit Thanks Curt
