Hello JC,
Thanks for the method. I deleted all my microsoft related passwords from my keychain and tried again, but no solution.
I get the same error from my iPad, iPhone and MacBook. Can't log in on any of these.
Interestingly, I downloaded Outlook app to my iPhone and it worked but didn't ask for password.
All my 365 Apps are logged out on all my devices, asking for me to log in again and give me this info. I took some screenshots.
Currently:
macOS:
Outlook: Can't log in, same error
OneDrive: Can't log in, same error
Office Apps: Can't log in, same error
iPhone:
Apple Mail Account addition: Can't log in, same error
Microsoft 365: Can't log in, same error
One Drive: Logged in (like WHY?)
iPad:
Apple Mail: Can't log in, same error
Microsoft 365: Can't log in, same error
Didn't try one Drive one this one.
WindowsOS:
Successfully logged in on all platforms.
My work is heavily affected by this. I feel so done with this non-sense but I don't want to change my provider.
