I am running the latest version 0.4.0 in an docker env on an ububtu 25.04 box

Outlook emails are not being synced due to authentification which is always set to PLAIN but needs to be LOGIN.
Even IMAP_AUTH_METHOD=LOGIN set in .env doesnt work. It is always set to PLAIN and been rejected.

Here's my log:

09:24:07.672] ERROR (242): IMAP connection failed open-archiver | [1] [0] err: { open-archiver | [1] [0] "type": "Error", open-archiver | [1] [0] "message": "Command failed", open-archiver | [1] [0] "stack": open-archiver | [1] [0] Error: Command failed open-archiver | [1] [0] at ImapFlow.reader (/app/node_modules/.pnpm/imapflow@1.0.191/node_modules/imapflow/lib/imap-flow.js:670:35) open-archiver | [1] [0] at process.processTicksAndRejections (node:internal/process/task_queues:105:5) open-archiver | [1] [0] "response": "3 NO AUTHENTICATE failed.", open-archiver | [1] [0] "responseStatus": "NO", open-archiver | [1] [0] "executedCommand": "3 AUTHENTICATE PLAIN", open-archiver | [1] [0] "responseText": "AUTHENTICATE failed.", open-archiver | [1] [0] "authenticationFailed": true

OpenArchive Msg: Authentication Failed . IMAP Connection Error: Invalid credentials (Failure)

PS:

  • same issue with Google account and yes, I used the app password and imap is on
  • other IMAP provider works
  • outlook pst upload works
