Spent hours on a document, saved it, emailed it and the recipient received the unedited document, I’ve been using Adobe products Acrobat Pro, Pro DC for years, at home on my personal account and at workand haven’t run into this issue with outlook before last week (that I’m aware of). Twice now this has occurred in the last week, I have to save as an optimized file for changes to stick... help!! Has anyone else experienced this???

Acrobat Pro DC using Outlook 365 at my office is where and how this happened.
