As with a nation of others, this is incredibly frustrating AND on a daily occurrence. Even in THIS forum, when presented with a spellcheck correction, we use the right mouse button! To state the design team decided to implement a function, which goes against the grain of all other spellcheck systems and does so without the option to make the user experience easier, suggests the team does not care about the user experience. To provide the user with an option to change from left to right mouse click for this function is not a massive undertaking.
Outlook is already a downgrade in terms of ease-of-use and user experience from MS Mail, which worked great until Microsoft retired it. And this particular issue is so bad, we as users are left wondering, who approves decisions that leave users frustrated. This isn't about installing a function people will eventually get used to and adjust to, this is a decision users will never get used to because all other systems use the right mouse button! Again... including here in the MICROSOFT FORUM where to correct a spelling requires a RIGHT MOUSE CLICK.
Please send this on to the design team. We need an option to change spellcheck corrections to the right mouse button.
