Hello,
I am a longtime Outlook and Exchange power user, but just upgraded to Outlook 365 on Windows 10 from Outlook 2016, utilizing the same servers (I have a personal 365 account and a university managed exchange account). One of the things I liked about the new version was the handy archive button next to each message in the preview pane. However, the button seems to change to the old delete button or disappear altogether randomly. Any insights as to why? It happens on both accounts.
Thanks!
