Outlook smtp settings are not working.

If you’d like to manage your Hotmail account using an email app, you’ll need to set up your POP3 or SMTP server and port settings in your email app. You’ll need the following info:

    POP3 server: pop3.live.com (port 995)
    SMTP server: smtp.live.com (port 25)

If port 25 has been blocked in your network or by your ISP, you can set the SMTP port to 587 with TLS or SSL Encryption (depending on which email app you're using).

Choose the Secure Sockets Layer (SSL) option for both POP3 and SMTP connections.

Choose the SMTP authentication for SMTP connections.

 Choose the outgoing server requires authentication option. (In most email apps, this option isn't checked by default.)

    User name: Enter your full email address.
    Password: Enter your Microsoft account password.

    If you don’t want email messages to be permanently deleted from your inbox after you download them to your mail program, select the Leave a copy of messages on the server option.

Prevent losing email in Hotmail when you've set up POP3

Hotmail has a feature that prevents losing email messages if you accidentally set up POP3 to delete them after reading them on the server. Here’s how it works:

    The first time that Hotmail receives a POP3 instruction to delete email messages after reading from an email app, Hotmail won't delete the messages. Instead, Hotmail moves the email messages that were successfully downloaded by the email app into a POP folder and out of the inbox. The POP folder is available in the Folders list.

    Hotmail keeps the email messages in the POP folder until you sign in to your Hotmail account and verify whether Hotmail should respect or ignore the POP3 delete command.

To verify your POP3 settings:

    In the upper-right of the Hotmail window, click Options, and then click More options.

    Under Managing Your Account, click Pop and deleting downloaded messages, and then select one of the following:

        Don’t let another program delete messages from Hotmail. (If your other program is set to delete messages from the server, we’ll simply move them to a special POP folder. They won’t be deleted.)

        Do what my other program says—if it says to delete messages, then delete them.

    Click Save.
