Outlook 2016 doesn't accept password or app password

Question

I have this problem - Outlook 2016 doesn't accept password or app password - and i think it is a growing World wide Microsoft problem :-(

See also here: https://www.reddit.com/r/Outlook/comments/19dx64p/outlook_2013_windows_10_suddenly_not_accepting/Outlook gives me this: (startede yesterday)

I have 2 PC's with HOTMAIL accounts in Outlook 2016 ...

They both have this error.

I do get mails ... but I can´t send mails. Yesterday it did work for 1-2 hours ... but right now the error is there all the time :-(

Please help me.

Thanks in advance

Answer 1

As I said above, I did leave the outlook.com account in the New Outlook app for several days. It did not stop my Outlook desktop app from asking for my Outlook.com password, over and over. So it's not a solution for me. I also tried the "Remove Cached Credentials" method posted previously, but that didn't stop MS from asking for a password over and over, either! I'm now looking at getting rid of Outlook desktop and using the eClient software option.

Answer 2

Thanks, Alessandro R and Andy Dobbs.

As you suggested, I tried setting up my outlook.com emails in the New Outlook app. Now I have folders from another account (used in the New Outlook app) showing in the MS outlook.com email account that I added! Very Weird. There are now two Inboxes, two Sent, etc. in the MS outlook account navigation sidebar. When I highlight one of the folders from the other account, I see the emails from that other account, AND the highlight on the folder in the navigation sidebar is shown in both accounts. It's like creepy! It makes it look like both accounts' data has been merged together somehow! I've tried change View setting from Focused to Non-focused, and back again, but that didn't do anything. What a debacle!

Nonetheless, I'll leave this outlook.com account in the New Outlook app for a few days to see if it solves the continuous asking for a password issue in my Outlook desktop software - the only reason to put this account in the New app.

So, I use Office 2016, and of course Outlook 2016, which is not compatible with the new authorization rules. I have been struggling with this entire depreciation of older Outlook versions for a few months until Microsoft finally let us know what was happening.

I downloaded the "Outlook for Windows" App. It is eligible for the new authentication rules, and is free from the Microsoft store. It is certainly different, and does not seem to have all the features of Outlook 2016.

However, once I downloaded the "Outlook for Windows" app, and set up my outlook.com email in it, then the Outlook 2016 install settled right down. I am running both at the same time. My original thought is I would take some time to learn the new "Outlook for Windows" app, while still using my more familiar Outlook 2016 app.

So, to my surprise, so far at least, there have been no disconnects from authorization for my Outlook 2016 since installing and setting up the "Outlook for Windows" app. Not sure what is going on, but as the "Outlook for Windows" app authenticates my outlook.com email, the Outlook 2016 app flies under the radar. Maybe.

Anyway, I am letting the "Outlook for Windows" app just run in the background, and I am still happily using my Outlook 2016 app with no disconnects from authentication. For now, at least.

I have Windows 10 LTSC, therefore without the Microsoft Store, what if I would like to install the App for Windows? Can't it, can't it be downloaded outside the Store?

Answer 4

Thanks. I'm a mail admin so I'm aware of that. I use gmail app to access gmail, Yahoo app to access Yahoo and Outlook apps to access MS 365 mailbox. I don't have Apple related stuff. I don't even want to access my free hotmail/outlook account using Outlook apps. I use a browser to access my free mailbox (outlook/hotmail).

As for this:

"I also saw another weird behavior that if I run setup on New Outlook and if it detects Class Outlook is installed, it somehow pulled those account setup information automatically without even asking,"

I think you're talking about Classic Outlook. That doesn't happen on my PC. I have to configure Outlook (new) app to access my business (Exchange) mailbox although I already got my Outlook 2016 desktop app configured to access that same Exchange mailbox.

Q: Does the free Outlook app support multiple accounts?

Yes
