Unable to install Icloud for Outlook..

WE uninstalled Icloud and icloud for outlook. On reinstallation the mail section is repopulated as before ( gmail and numerous labels. ) if this was a clean install ( we deleted both programs via Apps in settings) how is it the gmail file was repopulated?

After deleting the 2 apps are there other files/folders which should be deleted?

In Outlook Classic the top bar does not include the usual ability to refresh/sync. Calendar and Contacts remain empty. Am using Win 11 pro (which is up to date) on a Dell laptop. Another indication that Icloud for Outlook was prevented from istalling.

I understand this is not an uncommom problem.

    For this Outlook Classic + iCloud scenario, the supported fixes in the available guidance are:

    1. Re-enable Outlook as the default handler, then repair Office.
      • Go to Start > Settings > Apps > Default apps.
      • Select Set defaults by app.
      • Find Outlook, select Manage, and make sure the file types are associated with Outlook.
      • Then run an Office repair.
        • For Click-to-Run, use Online Repair.
        • For MSI-based, use Repair.
      • Restart the PC, open iCloud, and check whether Calendar and Contacts sync.
    2. Check whether Office was installed from the Microsoft Store.
      • If Office was preinstalled or installed from the Microsoft Store, it may not work with iCloud.
      • Go to Start > Settings > Apps.
      • Find Microsoft Office Desktop Apps or another installed Office entry and Uninstall it.
      • Restart the PC, then reinstall Office using the supported reinstall process.
    3. If iCloud fails to load in Outlook Classic for Calendar, Contacts, or Tasks, uninstall and reinstall iCloud.
      • For Outlook 2010, 2013, and 2016, Microsoft’s documented workaround for the MAPI load error is to uninstall and reinstall iCloud.
      • For Outlook 2016 specifically, iCloud for Windows 5.1 added Outlook 2016 support and fixed the repair/restart prompt issue.
    4. If the issue is specifically iCloud Mail account setup in classic Outlook, add it as a mail account separately.
      • Calendar/Contacts sync through iCloud for Windows is separate from adding iCloud Mail as an email account in Outlook.
      • If mail setup fails even with the correct password, an app-password may be required.
      • In classic Outlook: File > Add Account.
      • If automatic setup fails, use Advanced options > Let me set up my account manually, then choose POP or IMAP.

    The provided guidance does not document deleting extra residual folders after uninstalling the apps, and it does not explain why Gmail labels reappeared after reinstall. The supported steps above are the documented path for this problem.
