Using New Outlook on Windows for professional communication and productivity
I'm now having the same issue and have been for two days now.
If it's a read email with no attachment, it's fine. However, if it's an email with an attachment, it refreshes the entire screen. Every time.
I'm on the latest version of Chrome in Windows 11. I was able to temporarily fix it by resetting permissions and clearing my cache, but the issue reappeared after a few hours.
