The short version
- Each has a real cost: Git licensed under GNU GPL version 2.0 as stated on git-scm.com/about; as open source software it has no paid tier or vendor price to compare; Microsoft Outlook microsoft is replacing the classic Win32 client with the new web-based Outlook, and the new one runs only web add-ins, not COM add-ins, so any line-of-business integration for CRM, dictation, document management or telephony must be rewritten or the desktop stays on classic until its support window closes.

- Coordinating open source development globallynot Microsoft Outlook

- Integrating with CI/CD and hosting servicesnot Microsoft Outlook
Microsoft Outlook
- Organisations on Exchange Online or Exchange Server where free/busy scheduling and room booking across everyone is a daily requirementnot Git
- Executive assistants managing someone else's calendar and mailbox through delegate access, which no IMAP client supports properlynot Git
- Regulated environments that need retention policies, legal hold and eDiscovery applied to mail centrally rather than per usernot Git
- Teams handling shared inboxes such as support or accounts, where permissions and tracking matter more than the mail client itselfnot Git
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Git
- Licensed under GNU GPL version 2.0 as stated on git-scm.com/about; as open source software it has no paid tier or vendor price to compare
- Git is a command line tool by design; graphical workflows and hosted collaboration depend entirely on third party GUIs and hosting services layered on top, per git-scm.com/about
Microsoft Outlook
- Microsoft is replacing the classic Win32 client with the new web-based Outlook, and the new one runs only web add-ins, not COM add-ins, so any line-of-business integration for CRM, dictation, document management or telephony must be rewritten or the desktop stays on classic until its support window closes.
- The new client's handling of non-Microsoft accounts synchronises mail through Microsoft's cloud rather than connecting from the machine to the provider, which several organisations' data residency and handling policies do not allow, and it is not an optional behaviour.
- PST and OST files are a single-file, corruptible and effectively unshareable store, and the new client's reduced PST support means years of personal archives sitting in those files need an explicit migration plan rather than carrying forward.
- Large mailboxes turn software problems into administration ones: search index rebuilds, OST files of tens of gigabytes and the mailbox quotas of whichever plan was bought, and the usual fix is archiving policy rather than anything a user can do.
- Against IMAP or Gmail you lose most of what justifies it, including free/busy lookup, room booking, delegate access, and retention and compliance policies, because those are Exchange server features rather than client features.
- The five or six products sharing the Outlook name have materially different feature sets, so internal documentation, training and support procedures must be written per platform and a user moving between desktop, web and mobile finds the same task done differently in each.

Questions people ask
- Is Git or Microsoft Outlook better?

Answered from the vendors’ own pages
Git: How much does Git cost?
Git is completely free and open-source software released under the GNU General Public License version 2.0 (GPLv2). There are no licensing costs for the core Git project.
SourceMicrosoft Outlook: What is the difference between classic Outlook and the new Outlook for Windows?
Classic is the long-standing Win32 application shipped with Microsoft 365 and Office LTSC. The new Outlook is a web-based client that replaced Windows Mail and Calendar. The most consequential difference is add-ins: the new client supports only web add-ins, not COM add-ins.
Git: Can Git be used for commercial purposes?
Yes, Git can be freely used for commercial and non-commercial projects. The GPLv2 license guarantees freedom to use, modify, and distribute the software.
SourceMicrosoft Outlook: How long will classic Outlook be supported?
Microsoft has stated support through at least 2029. That is a planning window rather than a reprieve, and organisations with COM add-in dependencies should be scoping the replacement work now.
Microsoft Outlook: Can I use Outlook with Gmail or another IMAP provider?
Yes, but with reduced capability. You lose free/busy lookup, room booking, delegate access and server-side compliance policies, because those come from Exchange rather than from the client.
Microsoft Outlook: Is Outlook free?
Outlook on the web and the mobile apps are free with a Microsoft account, and the new Outlook for Windows is included with Windows 11. The classic desktop application requires a Microsoft 365 subscription or an Office perpetual licence.
Microsoft Outlook: Will my COM add-ins work in the new Outlook?
No. The new client supports only the cross-platform web add-in model. Vendors must publish a web add-in, and where they have not, the choice is to stay on classic Outlook or replace the integration.
