Searched till my fingers bled; gave up and installed the free "Windows Outlook", but it was a mess that Outlook data file cannot be accessed I can't take. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Windows 10 will reach EOS (end of support) on October 14, 2025.

Some users on macOS10.14 have experienced issues logging back into Mac Mail after Modern Auth is applied to their accounts. Specifically, after successfully responding to the Duo prompt, the pop-up window will remain blank except for a spinning icon and never finish adding the account to the application. This issue has been resolved by having users connect to the UO VPNwhen initially setting up their account with Mac Mail. After logging in successfully once while connected to the VPN, any removing or re-adding of Outlook Not Sending or Receiving Email the account again to Mac Mail should not need the VPN. In many cases, simply removing the account from the application and re-adding the account using the standard Sign In method will resolve any issues being experienced when Modern Authentication is first turned on for an account.

The currently configured authentication methods can remain unchanged. For example, if Windows Integrated Authentication is configured as the primary authentication method, it can remain configured this way. Loginto server outlook.office365.com with username[Duck ID]@uoregon.edu failed. Once your account has Modern Authentication enabled, you can no longer pull your UO email into Gmailand/or reply from Gmailon behalf of your UO account. This page contains information on what errors may come up when setting up your email with Modern Authentication (Modern Auth), and what steps are needed to resolve them.

Gmail

• If the error you are encountering is not listed, please create a ticket on our Email and Calendar Help page for assistance.
• This does not enable any oauth list entry that may be available for that server.
• Additionally, accessing email through a web client will continue to work, even if an application is having issues.
• App password is not needed so long as you’re using a modem version of Outlook.
• Outlook 2013 supports MA but requires a registry entry as already mentioned.
• If it continues to be problematic, you may need to either a.) Remove any related credentials from the users credential manager in Control Panel, it b.) Create a new outlook profile.
• I have confirmed that on two different PCs that are accessing the same mailbox with the same version of Outlook, which is the latest version from Microsoft included within my Office 365 package.

I have a couple of PCs that access the system on the same account from Win 10. Both are affected in the same way in that Outlook is constantly asking for a username password ( not using the modern authentication dialogue box ). I’ve tried various registry changes that I’ve found from Googling, tried changing the password, tried re-installing Office and also enabling disabling MFA. Microsoft will soon phaseout Basic Authentication and replacingit with Modern Authentication.

iOSMail

Removing and re-adding the account using the standard Sign In method will resolve this error. My concern is that MS will force modern authentication soon, and switch off basic authentication. I therefore have a workaround, but not a solution. Is there some kind of setting within O365 that’s forcing Outlook to use basic authentication ? Other apps are using modern authentication perfectly well, including Teams. I authorise the applications after installation with modern authentication, and OneDrive client uses it oo, so it looks like it’s only Outlook that’s forcing basic authentication.





Please report suspicious activity using the "Report Abuse" option. We recommendusing Outlook on the web to check your email or consider configuring a supported email client. I have also followed the troubleshooter in outlook where a MS tech gives you suggestions ( very slowly ). They suggested clearing credentials, which I have already work offline mode stuck tried. Outlook is working on my phone, and I can access everything via the office.com web site. Now I am constantly being asked to enter passwords for two of my Comcast addresses (my Gmail address works fine).
