Outlook 2016 doesn't accept password or app password

Well, I came to conclusion what to do here (with outlook 2016) or an old mail programs/applications.

1. change to 2 steps authentication (verification) - outlook.com security options.
2. create an app password - outlook.com security options - copy your app password, and remember it.
3. at account setting delete old your ****@outlook.com account settings (outlook 2016)
4. at account setting add new account as ******@outlook.com. The password should be the password from app password.

Anyways, only way to work with old outlook apps (2010/2013/2016) for windows is using app passwords instead of regular passwords (2 steps verification).

I wonder how long this method of app passwords will work with gmail.com and/or outlook.com.

When this option of app passwords will stop working, we will have to change to an updated outlook program (2021), or work on outlook on the web. The problem with this, is that we will have also to update operating systems, because not everything is working with old OS such as windows 7 or windows XP.

Software companies, are forcing the users to advance, with upgrading OS and programs, otherwise, they will not be able to show profits.

I keep reading in these posts about OAuth and I haven't the foggiest idea what that is.

Hi David - I’m not as versed as others in this conversation so I’m hoping you can explain how a current paid M365 user, who’s been getting the password error messages in iOS installations, can fix the issue. In an iOS install email process, I have both a Microsoft Exchange option (which I’ve used for years) and an Outlook.com option which I’ve recently used to try to fix the password issue, and has been more stable. Is one better than the other in terms of security and/or password stability? Which option should I be using? Thanks.

Hi David,

thanks for your response. What I do not get is the following:

BlackBerry Hub+ does support 2FA, but only for business accounts (it links to Azure Auth services).

My question is: Does Microsoft support modern Auth via EAS for outlook.com? So would it be possible for vendors such as BlackBerry to update the app to support modern Auth via EAS? This is not clearly stated here.

I also contacted BlackBerry to ask for modern Auth support for personal outlook.com accounts, but I am sure it would be also a good idea that you also contact them as you offered.

Hi there - Sure, let me try to explain a bit. As mentioned briefly in the known issue article, there is increased levels of bad actors that attempt to do brute force password attacks which targets different accounts that generate high volumes of authentication requests while they try to find a password that works to gain entry. The Outlook.com Service has throttling in place to handle these spikes, which has the side effect of increased authentication prompts.

We will continue to adjust the throttling policies where possible trying to always balance the impact to customers while trying to ensure we are protecting our customers' accounts.

This is why we recommend moving over to OAuth when possible, to help ease and quickly improve your experience you are having.
