I’m trying to test Delta Chat with both my Outlook and Zoho emails, the latter with the IMAP setting turned on. Neither has 2FA enabled When I try to authenticate with my email @outlook.com and the correct password, it shows the following error message: `No response: code: None, info: Some("LOGIN failed.")` After manually setting up the IMAP and SMTP addresses and ports and trying again, after some minutes it showed: `connection failure (os error 10060)` - Nothing showed up on my outlook account’s activity, no new login attempts registered. With zoho, without manually configuring IMAP and SMTP I get `Configuration failed. Error. Cannot login as "myemail@zoho.com". Please check if the e-mail address and the password are correct` - They are correct, same as with outlook. After manually setting up the IMAP and SMTP, the error becomes `Configuration failed. Error: Trying imap: myemail@zoho@imap.zoho.com:993 security=Ssl certitifcate=strict oauth2=false socks5_config=None... Error: Cannot login as "myemail@zoho.com". Please check if the e=mail address and password are correct.` `no response: code: None, info: Some("[AUTHENTICATIONFAILED] Invalid credentials(Failure)")` Looking around on Google and DDG, it’s likely that these two services are requiring some extra configuration that I might be missing? I tried to set them up with K-9 mail on my phone, and both worked, although for Outlook it opened a web page to login, not unlike how Delta Chat did when I tested with my google email (which worked, as did a test email I set up at [mailo.com](http://mailo.com)) Am I doing something wrong? Did I miss some configuration? ---

Connection failure means you have incorrect server hostname or port. For [outlook.com](http://outlook.com) it should be [outlook.office365.com](http://outlook.office365.com) server, port 993, TLS for IMAP and [smtp-mail.outlook.com](http://smtp-mail.outlook.com) (or [smtp.office365.com](http://smtp.office365.com) that Delta Chat uses by default and that is stated in [https://autoconfig.thunderbird.net/v1.1/outlook.com](https://autoconfig.thunderbird.net/v1.1/outlook.com)), port 587, STARTTLS for SMTP: [POP, IMAP, and SMTP settings for Outlook.com - Microsoft Support](https://support.microsoft.com/en-us/office/pop-imap-and-smtp-settings-for-outlook-com-d088b986-291d-42b8-9564-9c414e2aa040) ---

Outlook web recently switched to require outh2 And deltachat does not support it at this time. ---

As for SMTP, my working configuration is `smtp.office365.com:587:starttls`, don’t remember why it’s STARTTLS. ---

Existing credentials aren’t invalidated. Change your password and then try to set up in deltachat. Or don’t, if you want your outlook to keep working. ---
