I have a Microsoft 365 Family subscription. I am trying to add my personal Outlook.com account, ******@outlook.com, to Outlook Desktop on Windows. The account was previously installed. Browser login works. Password works. Authenticator works. Outlook forces Windows Hello/passkey setup and fails. Error Code 2148073526, Tag 7q6ca.
I am adding [email protected] to Outlook Desktop on Windows.
The account was previously configured in Outlook and was removed.
I can successfully sign into the account in a browser.
My password works.
Microsoft Authenticator works.
Both automatic and manual Outlook account setup force Windows Hello/passkey enrollment and fail.
