Sending, receiving, and organizing email in Outlook on the web for business
Solution found by a colleague who clicked on paste and instead of the window closing and doing nothing, it triggered a prompt window that says "outlook,com want to see text and images copied to the clipboard" along with "Allow" and "Block" Buttons ( I have no recollection of seeing this prompt nor did it appear when I attempted to paste, not even after restarting the computer) I guess one can click allow OR click on the lock icon to the left of the outlook URL and turn on Clipboard in permissions- problem solved.
Now the only question is why did this even happen at all, since I didn't change any permissions ?
Thanks Noel,
I clicked the lock icon and turned on the clipboard. Microsoft support was unable to help and I finally found your answer after 3 hours of Google.
