The short version

  • Each has a real cost: GitHub Desktop there is no official Linux build; the application ships for Windows and macOS only, and the community fork at shiftkey/desktop that packages it for Linux is maintained separately and lags official releases, so a mixed-OS team cannot standardise on one client.; 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.
  • They diverge on capability: GitHub Desktop covers Line-level staging, Microsoft Outlook covers Exchange calendar integration.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

GitHub Desktop

  • There is no official Linux build; the application ships for Windows and macOS only, and the community fork at shiftkey/desktop that packages it for Linux is maintained separately and lags official releases, so a mixed-OS team cannot standardise on one client.
  • Submodules are effectively unsupported: the app shows a submodule change as an opaque single line and gives you no way to initialise, update or navigate into it, so any repository using them needs the terminal anyway.
  • History rewriting is limited to squashing and reordering local commits by drag and drop; interactive rebase, fixup chains, editing an old commit's contents and bisect are all absent, which is exactly the set of operations a beginner needs help with most.
  • Pull request features only exist for GitHub remotes, so a team on GitLab or Bitbucket gets a plain Git client with an empty pull request pane and no review or checks view at all.
  • Commit signing with a key that requires a passphrase generally fails, because the app cannot surface the pinentry prompt, and the resulting error message does not say that is the cause.
  • GitHub staffs it lightly compared with its web and CI products, so long-standing feature requests and bugs sit open for years; if you file an issue you should plan around it rather than expect a fix.

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.

Answered from the vendors’ own pages

GitHub Desktop: Is there a Linux version?

Not an official one. GitHub ships Windows and macOS builds only. A community fork, shiftkey/desktop, produces Linux packages, but it is maintained by volunteers and trails the official releases.

Microsoft 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.

GitHub Desktop: Does it work with GitLab or Bitbucket?

For plain Git operations, yes: you can clone, commit, push and pull against any remote. The pull request, review and checks features only work against GitHub.com and GitHub Enterprise.

Microsoft 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.

GitHub Desktop: What does it cost?

Nothing. It is free and the source is published under the MIT licence, and it is separate from any GitHub plan you may or may not pay for.

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.

GitHub Desktop: Will it handle submodules?

No. Submodule changes appear as an unreadable single-line diff and there are no controls for initialising or updating them. Repositories that use submodules need the command line.

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.

GitHub Desktop: Do I still need to learn Git?

For everyday work, no. For recovery, yes. Anything beyond the curated set of operations, including interactive rebase and reflog recovery, happens in the terminal, so a team using it should have at least one person who knows Git properly.

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.

GitHub Desktop: Does it work with GitHub Enterprise Server?

Yes. It signs in to GitHub Enterprise Server and GitHub Enterprise Cloud as well as GitHub.com, and it honours organisations that enforce SAML single sign-on.
