Technical problem with your Windows Hosting?

How do I Change the Outbound SMTP Port in Outlook?

Some Internet Service Providers deliberately block communications on port 25 to prevent the spread of unsolicited commercial email. This can be overcome by using the Alternate SMTP port, 587, as this can be enabled for all levels of Server Intellect’s hosting services.

If you require any further assistance, please do not hesitate to contact our Support Team available 24/7!

Microsoft Office

First, open Microsoft Outlook then click “Tools“, then “Email Accounts“.

Click “Next” then highlight your account and click “Change“, and then click “More Settings“.

Select the “Advanced” tab and change the Outgoing server (SMTP) port number to 587.

Click “OK” to confirm the change.
