do you have your automatic checking set to 15 minutes of more? If not, that is what you get when you set it to less.

Yes i have the DEFAULT the thunderbird choose and are 10 minutes. So it's not my fault but thunderbird default settings when you add an mail.

How i solve that? I raise this time from 10 minutes to more?

You shouldn't see that password prompt if the authentication method is OAuth2. Also, the outgoing should be smtp.office365.com, 587, STARTTLS, OAuth2, email address. When you connect with OAuth2, a browser-like window will appear where the account password should be entered to allow TB access.

I choose what thunderbird suggest me when i put the mail i DON'T choose anything else. So.....

And wait to check what is the settings to hotmail accounts: imap outlook.office365.com port 993 And why at gmail and yahoo that is the same port 993 don't have any issues?

and i don't know where i can see the other settings for the inbox servers.

As i remember i have done the oath2 verification when i put the mails.

Even NOW I TRY to put a new mail the thunderbird settings for imap was outlook.office365.com port 993.

So something is wrong with mozilla thunderbird NOT ME.

Do you tell me to change the port into 587? But the same port 993 use the gmail and yahoo mail servers without any issue so what is happening with outlook mail servers???

Even NOW I TRY to put a new mail the thunderbird settings for imap was outlook.office365.com port 993. So something is wrong with mozilla thunderbird NOT ME.

If that is the case, why does it work for me and not you?

Each mail provider has setting decided by the mail provider as to what will be needed to connect to the mail server. So your settings for Yahoo or even Gmail have no relevance to what Microsoft decide is their requirement.

This is the settings Thunderbird will use for outlook domains. https://autoconfig.thunderbird.net/v1.1/hotmail.com

Now to the important part of this. You have two accounts with Outlook for every mail address. One to receive mail, which will be an IMAP or POP account unless you use the OWL addon. The other will be an outgoing account and it will use the port 587. Your incoming account will use port 993 or 005 depending on if it is IMAP or POP. I know you probably find all this confusing, but setting up a mail client is an exercise in copying what the provider tells you to use, not creative guessing.

Most folk that have issues setting up account with outlook have issues with their antivirus causing the process to fail. I use windows defender which has few components that mess with mail. Third party antivirus products have spam, scam and advanced threat detection, which means generally it is that far integrated in the download process that when it fails, everything fails. I do not have that sort of product and have no issue. I also do not use a VPN which is another prime cause of mail download failures.

What is that??? I don't undestand anything at all. Why thunderbird when you add one hotmail account DOESN'T SUGGEST YOU THE CORRECT SETTINGS and simply suggest you the imap outlook.office365.com port 993?????

Is therre a way to make thunderbird suggest the correct one everytime i add a hotmail acc?

Me neither i don't have an active antivirus. The anti-virus i have i use it when i want not automatically. But even this way still have these issues and error messages from thunderbird....

So what i do to stop have these thunderbird error messages????

I believe the imap is the better and more newest correct? So i use the imap settings THUNDERBIRD SUGGEST ME.

So please tell me what i must do to get rid these error windows/messages????

Ignore the settings suggested by TB, and use the ones in these pictures:

https://support.mozilla.org/en-US/questions/1417298#answer-1588949

Only at hotmail accounts or to all mail accounts????

And this is for the incoming and outgoing?

An i don't use vpn or antivirus.

Edit: i change all hotmail accounts and now it bring me a new error. time limit over for server smtp.office365.com

And where i put ingoing settings for every outlook mail? And now it bring me always this issue at photo.

This is what I use for HotMail and have no problems:—

Under Account Settings > Server Settings

Server Name: outlook.office365.com Port: 993 User Name: <my name>@hotmail.com Connection Security: SSL/TLS Authentication Method: OAuth2

Now look down the left hand column on the screen click "Outgoing Server (SMTP)."

That brings up a list for all your accounts.

Click the one that's causing trouble then click Edit and make sure the settings are:—

Server Name: smtp.office365.com Port: 587 Connection security: STARTTLS Authentication method: OAuth2 User Name: <your HotMail e-mail address>

I did have problems similar to you a few weeks ago but that was down to MicroSoft changing to OAuth2 authentication and doing the above fixed it.

You haven't said what version of Thunderbird you are using. I had to upgrade from 45 as that was too old to use the modern method.

But this is the thing. At the accounts it bring this i have correct and now i the settings you mentioning but the messages still appear.

And i have the port 993 but someone tell me to change it to 587... Guys make your mind what is the correct????

Based on this "https://support.microsoft.com/en-us/office/pop-imap-and-smtp-settings-for-outlook-com-d088b986-291d-42b8-9564-9c414e2aa040"

The correct settings for hotmail accounts are:

IMAP server outlook.office365.com

IMAP port 993

IMAP encryption SSL/TLS

Authentication Method OAuth2/Modern Auth

And read these post at redit to for thunderbird 115 https://www.reddit.com/r/Thunderbird/comments/16phv14/after_upgrading_to_version_115_office_365_smtp_is/

And this from microsoft site https://answers.microsoft.com/en-us/outlook_com/forum/all/240124-thunderbird-115-problem-after-upgrade-with/94b6fb40-34f7-430b-bf9d-552fcd675eee

So what the heck is happening????? It is thunderbird bug/problem mozilla still don't fix it?

And plus to all these there is this to "connection to server outlook.office365.com times out"

And plus to all these there is this to "connection to server outlook.office365.com times out"

Do you have an antivirus program that thinks it is helping by scanning email? They are a notorious problem with email. The fact that the connection attempt is timing out makes me think the problem is not Thunderbird. Generally if your settings are wrong you get a connection refused message. Timeouts are almost exclusively the realm of third party programs. Although I was made aware yesterday of issues with Verizon routers and their family protection. So that is a new one on me, but do you perhaps have Verizon?
