Can’t reply or forward via safari on ipad

All of a sudden I keep getting an error message every time I try to reply or forward  a message. This is only happening when I use hotmail on my iPad via Safari. It worked fine for years before yesterday. Coincidentally I recently received a security info replacement message when I logged into hotmail. I hope that was not a virus or the cause of this however I don't think that is the case since my account works via other access points (different computer, app).

This is is what is says when I hit reply on a message.
