Hello,
im experiencing issue, where my primary account doesnt switch to HMA (in Outlook connection status it shows "Autologon*" instead of "Bearer*")

When i create new profile (im adding another mailbox to my outlook), it DOES use HMA.

Recreating profile didnt work, reinstalling office didnt work, all other user accounts in company use HMA - there should be no problem with settings on Organization level.

Sometimes i test some settings, i might set up some policy on my mailbox/account preventing to use HMA. I have no clue how to find the source of my problem, why my particular mailbox dont switch to HMA and other mailboxes have no problem.

Some tips?

    Hello,
    thanks for your assistance.

    Ex: 2016 latest CU hybrid configuration (mailboxes are on-prem only)

    I will be able to test connection from another computer on Monday.. Please wait for further informations.

    Regards

    Hello,
    i made we performed test from another computer, it shows Bearer* on my mailbox.. so its not something i can solve on Exchange / mailbox side, it looks like I need it to solve on my computer (without recreating whole user profile I wish)

    So,
    on my computer:
    my mailbox uses Autologon*, other mailboxes shows Bearer*.

    I cleaned up Credential manager, created new Outlook profile, reinstalled Office 365 .. nothing works.. Recreating whole user profile will be my last attempt...

    let us know! I figured that was it :)
    Also check the registry:

    https://learn.microsoft.com/en-us/outlook/troubleshoot/authentication/outlook-prompt-password-modern-authentication-enabled
    Make sure this isnt set as well:

    HKCU\SOFTWARE\Microsoft\Office\15.0\Common\Identity\EnableADAL
