Office365 authentication, Can not login with office 365 account
 
#1
0  
Hello,
O365 account was working till few days ago it started to ask for login.
When i enter my username(email), then password, then MFA (tried both MS auth app and SMS password) it opens just white screen:

https://prnt.sc/lpYlwroSJMCH

I have tried to copy top link into few browsers where i was logged in already, and fresh page where i needed to login, but still white window and nothing.
I have tried to setup on different computer, different Bat version (trial), but still same issue.

Maybe somebody faced this kind of issue?
Thanks

I have the same problem on two different o365 accounts. Logging into them has not worked for a few days.

It could be that Microsoft tweaked something in their OAUTH2 authentication procedure (I don't use it so can't verify). Best to contact  support using the link above.

Then what is the licence paid for? So that I can now be referred to microsoft support? I think it's high time to switch to another software, which is a shame because I've been with Bat for many years.

I have been in exactly the same situation for a few days.

The Bat! support, not Microsoft. Link above.

The first thing I did was open a ticket in support of TheBat. But so far no response :(

Or maybe someone is embracing this oauth2 from Microsoft? I wonder if it is possible to manually enter the data in the link https://login.microsoftonline.com/common/oauth2/v2.0/authorize (which TheBat prepares) just to change possible parameters to make the link accepted as valid. I've done a bit of testing and for a different "scope" the authorisation passes, but I don't really know how to use it.

Open a ticket with The Bat Support. (I already did.)

I am having the same problem, starting May 6, only in Microsoft hosted IMAP (OAuth2) email. Three other users I know have the same issue. GMail also uses OAuth2 but The Bat is able to receive/send email without issue. Only Microsoft accounts are affected.

This issue also happened one year ago around May 20, 2024. Bat support informed me it had something to do with a certificate on the backend and it was fixed two days later.

This outage has now lasted 4 workdays  :o . Thunderbird is able to access Microsoft email, but I prefer the features in The Bat and would rather not migrate all my folders. It's unclear whether this was a change on Microsoft's backend, or something with The Bat.

To me, TheBat support wrote back like this:

There have been no changes on our end in regards to the OAuth authentication for Outlook.com/Office365. We have tried to set up an account in The Bat! as well as in other email programs and we got stuck at the step where Microsoft has to send us a code via email in order to complete the authentication. We cannot even sign into the respective account using a web-browser due to the lack of the email with the code which has to be
sent from Microsoft when in fact Microsoft doesn't send it. We are sorry we have no solution here. Hopefully, Microsoft will fix it on their end soon.

Sad :(

Probably both: MS changing something, and TB's code not being robust enough to withstand the change. Let's hope it gets fixed soon.

Unfortunately I got exactly the same response from support, it seems like they have already thought of a standard response.
While I still can't access email using Thebat. I don't know who the solution depends on but in this case I think that support is not up to the task. It's a big shame since I still think Thebat is a great email client.

Today we are able to access email again. Anyone else?

I made a bunch of changes in our Microsoft 365 Admin Center, Exchange Admin Center, and Entra ID (aka. Azure ID) over the weekend to get rid of MFA (multi-factor authentication) but I was still not able to complete login (the OAuth window would still remain open and could only be closed by clicking "Cancel"). This morning, all our users (3 of them) were able to complete authentication.

I'm not sure if it was something Bat support fixed or a result of my changes. You may need to restart The Bat, possibly even reboot to clear any connection cache. Anyone know of a different way to do that?

Anyone still having issues:
  • Users with personal Microsoft accounts (hotmail.com/outlook.com) can enable app passwords to get around MFA (multi-factor authentication). Go to User > View Account > Security > Add Sign-in Method > Choose: App Password
  • Business/school users need to disable Default Security but enforce MFA for users to allow them to create app passwords. Go to User > View Account > Security Info > Add Sign-in Method > Choose: App Password

I got the same reply from Support. To help, I created a Microsoft account and sent it to them in my ticket. I also tried learning Pascal/Delphi over the weekend to see if I could either diagnose the problem or create a successful connection. OAuth2 is a complicated process for me right now... Any programmers want to collaborate with me?

I have tried to login today, still no luck. Security defaults are turned off, but we have MFA, so tried just with account password and MFA but same white window.
So at your case all 3 users used App password to authenticate and after entering app password no MFA was required?

Sorry, I should have been clearer. I was UNABLE to get app passwords to work correctly. At first, it was a problem finding HOW to create them, which is why I documented it. Once created, I was unable to get them to work, I assumed because we have a Microsoft business account, which enforces certain restrictions which are hard to find and disable.

LATEST NEWS:
Fix 1: Bat Support has published an app update which address Microsoft OAuth issues. They have shared the release with me (v.11) via support ticket. It is not published on the Downloads page, so please create a support ticket if you need the update. (Unfortunately, the update did not fix the issue on my Win10 PC. Next, I will try a full install and fresh reinstall of The Bat.)

Fix 2: I was able to get authentication to work for version 10.3.3.16 (not v.11) by creating/updating an App Registration in Entra ID, creating a Conditional Access policy in Entra ID (requires Entra ID P2 subscription) which allows users from specific IPs (our office IP) to bypass MFA, and assigning The Bat app registration to Conditional Access policy. I am saving these steps in case of future issues with Microsoft OAuth2 authentication.

I for one couldn't stand it and changed my mail client. It's a shame because I've been with TheBat for over 20 years.

Good luck for all!

Best,
Tomek.

I can assure you that the team is working hard and the problem is very close to being solved.
A little more patience.

I'm facing the same dilemma whether to change programs. As much as I have been using Bat for 20 years, I can't afford that every month or two, MS accounts (of which I have about 10) stop workin or make me authorize myself every 2 minutes. I waste time and nerves writing to support, looking for solutions, tweaks or other hacks to make my mail work.

I'm testing a beta version that support has sent me and I can tell you that it finally works.I imagine they will release the stable version soon, that's why I said patience.

For me, this is the straw that broke the camel's back. I've been using TheBat! for 25+ years, but this is too much, and it shows how poor support this software has. I submitted a ticket four days ago, and all I've got is "The issue is caused by the recent changes on Microsoft's servers - we will soon release a version with a fix for this issue."  Not even a hint of when this will be solved.

Can anyone recommend an email client where it is decently easy to migrate all my folders? 25+ years of saved emails is the only reason I've been tolerating TheBat.

And you write that directly underneath a message that says that a working beta is already available..

How can they know in advance how long development, testing and compilation will take when the full scope of the technical challenges is unknown?

I don't think so.

I have changed to [CENSORED-DvR] is a fully-featured email client for Windows and macOS with a clean and easy-to-use interface.
Although I don't know if you will read it, as it will probably be removed. Censorship is here :)

Best,

I do not allow discussion of competing products. That's not censorship, it's simple politeness. Ritlabs is kind to offer us this platform and we should not abuse their hospitality. Also, I don't want competitors to come over here and use our forum for advertising or to create chaos, as I've seen happen with other products.
