Have a Personal Premium O365 account but can't install Outlook Desktop

Question

Have a Personal Premium O365 account but can't install Outlook Desktop. I've tried everything for hours but no progress. I don't want the Store version because it does not have the AI features.

See https://support.microsoft.com/en-us/office/install-or-reinstall-classic-outlook-on-a-windows-pc-5c94902b-31a5-4274-abb0-b07f4661edf5.

Answer 2

Hello, when you install Office do you see apps like Word and Excel installed but not Outlook?

Open Settings, then Apps, then Installed apps, find your Office install, select Modify, and run an Online Repair. After it completes, restart your PC, then press Windows key and search for Outlook again. If it still does not show, open Word, go to File, Account, and confirm you are signed in with the correct Microsoft 365 Personal account, then update Office and reinstall from the Office site while signed in. This forces a full repair and ensures Outlook desktop is included and properly registered on your system.

Answer 3

For a Microsoft 365 Personal/Premium (home) subscription, the classic Outlook desktop app is installed as part of the full Office desktop apps, not from the Microsoft Store.

Use these steps to get the desktop Outlook instead of the Store/New Outlook version:

1. Confirm the subscription type
   • Sign in at https://www.office.com with the Microsoft account used for the Personal/Premium subscription.
   • Verify that the account shows an active Microsoft 365 Personal or Family subscription that includes “premium Office apps” (Word, Excel, PowerPoint, Outlook, etc.).
2. Remove existing Office/Outlook apps
   • In Windows, go to Settings > Apps > Installed apps.
   • Uninstall any existing Microsoft 365/Office desktop apps and any “New Outlook” or Store-based Outlook apps.
3. Clear old work/school account ties (if the device was ever joined to an organization)
   • Open Settings > Accounts > Access work or school and disconnect any old organization account.
   • Open Control Panel > Credential Manager > Windows Credentials and remove entries that reference old organization accounts (especially Office/Work/School-related ones).
   • Optionally clear identity caches as in the Microsoft Q&A guidance:
     • Delete contents of these folders (Windows + R, paste each path, press Enter, then delete contents):
       • %LocalAppData%\Packages\MSTeams_8wekyb3d8bbwe
       • %LocalAppData%\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy
       • %LocalAppData%\Microsoft\OneAuth
       • %LocalAppData%\Microsoft\TokenBroker
       • %LocalAppData%\Microsoft\IdentityCache
   • Restart Windows.
4. Install the full desktop Office (including classic Outlook)
   • Go back to https://www.office.com and sign in with the same Microsoft 365 Personal/Premium account.
   • Select Apps on the left.
   • In the upper-right, select Install apps. This downloads the Office installer.
   • Run the downloaded installer; it installs the full desktop Office suite, including the classic Outlook desktop app (not the Store/New Outlook version).

If the subscription is active and the installer is launched from the Office portal as above, the result is the classic Outlook desktop client with the full feature set available for that subscription, rather than the Microsoft Store “New Outlook.”
