Configuring preferences and options in Outlook on the web for business
"there is no setting in Outlook or Chrome that allows you to change the spellcheck feature back to right-click. This is a design choice made by the Outlook team to improve the user experience."
This "feature" reduces productivity and sullies the user experience.
It is bad enough that we are likely to drop Outlook as our email client, if this "feature" is not removed, and uniform operation restored.
