Outlook imap issue

Copper Contributor

While configuring IMAP, We are getting below errors attached in the screenshots. 

The PHP INI file has "IMAP" enabled. 

Our passwords are correct. 
Error Message: (E_WARNINGJ Authentication failed for user imap_open(): Couldn't open stream {outlook.office365.com/imap/551/nova1idate-cert}

Please double check on follow:

 

  1. Server Settings: Ensure that the IMAP server address and port number are correct.
  2. SSL/TLS Settings: Verify if your server requires SSL/TLS and that it’s correctly configured.
  3. Firewall/Antivirus: Sometimes, these can block IMAP connections. Make sure they are not interfering.
  4. PHP Extensions: Confirm that the php-imap extension is installed and enabled in your PHP configuration.

@Kidd_Ip Thanks for the reply.
We have reviewed all the points you mentioned, yet the same error persists.

My IMAP and OPENSSL settings are enabled. Configuration works fine on Gmail.
The settings I am using are:
Host: outlook.office365.com
Port: 993
Email: {my_email}
Password: {password}
We are waiting for your response. Kindly get back to us at your earliest convenience.
