Using classic Outlook for Windows in business environments
John,
I checked on Firefox and I believe you're correct, I cannot find any settings to prevent using the clipboard, so I'm not sure what the issue could be there.
MacPheDJ,
The lock icon is just to the left of the "https://" in the browser in Edge. My coworker had the option to copy and even had the option to paste on the right-click menu, but when pasting, nothing would happen. I replied to Risdon & Risdon because their issue sounded similar to the one we were having, not necessarily all the issues for everyone on this thread. I apologize for upsetting you, I was only trying to help others with the solution I found. If the paste option is not showing up, that sounds like a different issue that I cannot help with. I don't work for Microsoft, I'm just a user trying to help where I can.
