Why does IMAP authentication fail on my outlook hosted email?-CodePudding

I am using IMAP to access an Outlook inbox.

I am authenticating as so, taking the IMAP info from the account:

    var imap = new Imap({
        user: user.name,
        password: user.pass,
        host: 'outlook.office365.com',
        port: 993,
        tls: true
      });

This returns the following error

Error: LOGIN failed.
    at Connection._resTagged (/node_modules/imap/lib/Connection.js:1502:11)
    at Parser.<anonymous> (/node_modules/imap/lib/Connection.js:194:10)
    at Parser.emit (node:events:527:28)

    at processTicksAndRejections (node:internal/process/task_queues:82:21) {
  type: 'no',
  textCode: undefined,
  source: 'authentication'
}

I can't find any info on this error, can you see what I'm missing?

CodePudding user response：

It looks like Outlook has recently stopped supporting Basic Auth through IMAP https://learn.microsoft.com/en-us/exchange/troubleshoot/administration/cannot-connect-mailbox-pop-imap-outlook

This seems to be the cause for the error. For anyone looking to get access to mail on an outlook server I'd recommend looking into creating an Azure app and using Microsoft's GraphQL API. That's worked for me.
