Configuring preferences and options in Outlook on the web for business
I am recommending that users revert to "old Outlook" while the seek out a product that completely replaces the defective "new Outlook".
Let's face it, if MS cared about the user experience, they would have never even considered tampering with an industry-standard.
I think that they have failed to realize that they are just one company in this industry, and they don't get to dictate standards.
That may have been the case "back in the day", but it is certainly not now.
IBM made this same mistake, and where are they now?
