Hello info_391

Hi, I'm Karl and will be happy to help you today.

First, both the server name and port setting are incorrect. Even if port 25 was correct, that port does not use encryption on any email account.

You should confirm the server settings for the account you want to use which is done by

#1 - Log into the account

#2 - click on the <Gear> (settings) icon

#3 - click on <View all Outlook settings>

#4 - click on <Mail> --><Sync Email> --> scroll down to the SMTP server settings which appear as shown in the attached screenshot

Also, just as a FYI, this forum is focused on the consumer use of an Outlook.com account via webmail (using a browser). Trouble-shooting WordPress mailing options is out of scope for this forum. All we can do is provide the Outlook.com server settings

*** please note that we do not work for Microsoft and have no access to any user account so there is nothing anyone can do or check from within the forum.
