Microsoft Office Outlook Alternatives for Mac

Alternatives to Microsoft Office Outlook for Mac with any license

Thunderbird

Thunderbird is a free, open source, cross-platform e-mail, news and instant messaging client. The project strategy is modeled after Mozilla Firefox. It supports POP (storing mail locally on your hard drive so that it can be accessed without an internet connection), and IMAP. It features excellent mail filter capabilities and management. Thunderbird has strong support for using multiple accounts and identities, including automated signature features.
- Despite its age, Thunderbird remains the most fully featured email client out there. Various add-ons can extend its functionality, it (now) has a built in calendar and, unlike Outlook, it's free, open source and respects your privacy. JohnFastman • Jan 2017 • 10 agrees and 8 disagrees
- Seems to be more secure than Microsoft alternatives and more easily updatable. Guest • Apr 2017 • 6 agrees and 4 disagrees
- For me it is the only alternative to Outlook, if you want power of Outlook and open source there is just no other app. wookahn624 • Jun 2018 • 1 agrees and 1 disagrees
- It is a really poor software, no featureas, it's complicated. Try to configure a signature with a logo and you will see.... Terrible!! Guest • Jun 2017 • 12 agrees and 23 disagrees

Apple Mail

Apple Mail changes the way you interact with your email every day. Mail displays your messages and open email side by side in a widescreen, two-column view. The favorites bar below the toolbar works much like a bookmarks bar in a web browser, giving you one-click access to your mail folders. A compact preview of each message — including the first two lines — lets you scan your messages at a glance.

Messages are automatically sorted by type, such as mailing lists, and mail with attachments . This approach to indexing allows for quicker access to messages.
