Free alternatives to Microsoft Outlook
1 free program that can replace Microsoft Outlook, a pairing checked by Radar's AI reviewer or by Radar.
Microsoft Outlook is an email program that also handles calendar, contacts and tasks. Office workers and companies use it a lot, often connected to a work mail server, and it is usually part of a Microsoft 365 subscription or an office suite licence.
Before switching, check these points:
- How your accounts connect. Standard mail protocols are easy to move, but work accounts on a company server may need the administrator's permission or special settings.
- Your calendar. Meeting invitations, shared calendars, reminders and availability checks are where problems tend to appear when colleagues stay on Outlook.
- Your archive. Export old messages and contacts before you change, and confirm that the new program can open the exported files.
- Rules, signatures, templates, add-ins and shared mailboxes you depend on, which usually have to be rebuilt.
- Search speed across years of mail.
Look through the list below for tools that cover parts of this work, and keep Outlook available until you are sure nothing is missing.
