I've got a brand new installation of Office 2016 on a brand new Surface Pro 4 running Windows 10. Several times a day when creating a new email or replying to an email I'll get the spinning icon and will never regain control of the message. I end up going into task manager and killing Outlook. Unfortunately I then lose the message that I was composing.
This is a plain vanilla installation of Office. I have not added any rules or add-ins.
Why does this happen? How do I fix it?
I've taken to using Thunderbird on other machines because it seems to be much more reliable and less quirky.
