Outlook. For one reason - you can extend its capabilities with add-ons.

And there are FAR more add-ins written for Mozilla Thunderbird than there
are for Outlook.
Plus Thunderbird handles IMAP email far better then Outlook...and you can
choose whether to have a Calendar or not...with Outlook you have it whether
you want it or like it or not...
