Connect outlook desktop to MS365 mailbox using imap

Question

Hi team,

we are scheduling migration from current email provider to MS365.

Our email account is configured for pop3s/smtps access and many folders are used under the account configuration. The best should be to add the MS365 mailbox to the same profile using IMAP and copy folders and messages from one account to the other. But every attempt to add the MS365 account was unsuccessful.

IMAP and POP3 are enabled for my mailbox, MFA is disabled for my user in Entra ID.

During configuration of the new account the password is not accepted but I am using same credentials used to login successfully to outlook web access.

Is there something I missed during configuration of the account.

Any advice?

Nick

Hi @Nicola Papapicco

Welcome to our forum!

Here are a few things you might want to check:

1. IMAP and POP3 Settings: Double-check that IMAP and POP3 are indeed enabled for your mailbox. If you are using an M365 account of the outlook.com, you can refer to this linkto check it up. If not, you may refer to the article: Enable or disable POP3 or IMAP4 access to mailboxes in Exchange Server | Microsoft Learn.
2. Password Issues: Ensure that there are no special characters in your password that might be causing issues during the configuration. Sometimes, certain characters can cause problems with authentication.
3. Server Settings: Make sure you are using the correct server settings for IMAP and SMTP. For MS365, the settings are usually:
   • IMAP server: outlook.office365.com
   • IMAP port: 993
   • IMAP encryption method: SSL/TLS
   • SMTP server: smtp.office365.com
   • SMTP port: 587
   • SMTP encryption method: STARTTLS

If all above do not work, it is proposed that please create a new profile, re-add your account to the new profile and check if the same issue still occurs.  

Hope it helps!
