I understand that you have login problem with your Outlook desktop add-in. Could you please try the following troubleshooting steps first and see if that solves the current login loop?
Uninstall Office 365 add-in if you still have this (We cannot use both Outlook desktop add-in and Office 365 add-in. Having both of them might cause issues.)
Re-run the installation via the new installer: Settings > Integrations > Email Integrations > HubSpot Extensions > Download button next to Outlook for desktop
I'm absolutely 100% sure, that I always had just one add-in at one time but it still didn't work. Nevertheless I uninstalled the Office 365 add-in again, reinstalled it but still the same result.
I have for sure the latest version of office but my computer still operates on win 10 and not 11. Not sure if this could cause a problem?
I have the role of a "Super-Admin" so I should have access to everything I guess.
I can't follow this instructions. Either I'm at the wrong place or there is just no Outlook for desktop to be find for the free version...
I thought internet expolorer is deprecated. I made the settings as desribed in the article but I was actually pretty sure, that's not supported anymore by microsoft.
#2: Outlook desktop add-in works with Windows 10 so it shouldn't be a problem.
#5: If you search for Internet Explorer on your computer, can you find it? The default browser for Windows 10 machines is Edge but Internet Explorer should be there as an installed program. Outlook uses Internet Explorer in the backend even if your default browser isn't Internet Explorer. So we need to change the settings in Internet Explorer and not Edge.
I will probably need to bring this to the internal team for further investigation, could you please share the following information?
Screenshot of your installed add-in (This will appear in the Add/Remove Programs list on your computer. It will also appear in the add-ins list within Outlook: File > Options > Add-ins)
Outlook Version (file > office account > about Outlook)
