Outlook 2016 doesn't accept password or app password

Hi AnotherBug - Let me see if I can help clarify your question. You mention that Both Outlook 2013 and 2016 hare setup with the OAuth regkey. Those versions do not support OAuth. Here is the exact snip from the updated issue page. Per the below, you will need to upgrade to a more recent version of Outlook, or use the Outlook.com web experience in your browser.

For the Mobile device question, if you are running the latest version of Outlook for Android or iOS you are good to go, again assuming you set it up via the default config and did not do a custom setup syncing via imap/pop. If you are having problems with auth prompts on your phone, I would recommend removing the account and then adding it back using the autoconfiguration that it will do.

Can you please clarify this a bit more?

Both Outlook 2013 and 2016 have multiple manual setup account types, including "Outlook.com or Exchange ActiveSync compatible service". OAuth regkey are also added. Isn't this basically what you are asking for?

The recommendation is too broad and doesn't give enough details for this to be actionable besides dumping older and very functional Outlook desktop W32/64 app, for the "New Outlook" PWA that are very crippled in features.

Also for mobile devices, what are we supposed to do? Already using Outlook app for Android. It's not clear if the Android app itself runs an EAS service or if it relies on the EAS service of the OS, but it, too, is supposed to support OAuth already. I don't see a lot of actionable steps.

Hi all,

The Outlook Team has updated the guidance about this issue, Outlook and other apps are unable to connect to Outlook.com when using Basic authentication - Microsoft Support.

A key take away is that everyone needs to work towards being on apps that support OAuth for Outlook.com. If you are using Outlook 2013 and Outlook 2016 an immediately available free option is to install the New Outlook, Outlook for Windows - Microsoft Apps. We will continue to update the guidance with learnings and status updates as we go.

I am getting tired of this. I think I am going to have all my MicroSoft related Email accounts deleted or just stop using them and switch to another Email provider. Maybe if we all do this, they'll get upset because of the loss of AD revenue and fix the issue. I am starting to think this is all a scheme to get us to buy a 365 subscription. All other providers work fine with Office 2013 until MicroSoft decides to do something that breaks them. Let's all stop using Outlook/Exchange related Email accounts (Outlook, Hotmail, MSN, etc.).

Same.

BTW I HAVE a 365 subscription, so this is obviously just a bug they've introduced at random and now can't fix.

I cannot believe this is still happening, have they even explained what caused it? I have 3 Outlook accounts & use Outlook 2013, sometimes the credentials pop up only comes up for 1, sometimes 2 but mostly all 3 & it is every time I open Outlook. Sometimes it takes 10 attempts to enter the password, other times it goes on much longer & there is no break between - as soon as I click save it pops up again.

What is most frustrating though is the response from Microsoft. I am using app passwords (& changed them when advised), I have the correct version of Outlook & I have it set to update automatically - all of this has been the case since this problem started yet nothing has improved.
