Who is affected? - Users of Microsoft email clients using SSL/TLS settings

What is affected - Users of the Microsoft email client typically are suddenly unable to receive emails

How do you fix this problem? - The article below shows how use the non-SSL, explicit SSL and explicit TLS settings

Updating your Micrsoft Outlook Settings use non-SSL settings

There have been reports of issues with receiving emails from customers primarily using Microsoft Outlook. The problem is the result of a large Security Update released to fix vulnerabilities in many of their office products. In the process of updating many of their office products, the settings for receiving email may have been affected. Web Hosting Hub's email functionality has not been affected, but customers may need to reset their email settings.

Here are the email settings for using non-SSL

Server name: mail.domainname.com (for both incoming and outgoing server)

Port numbers: incoming = 110 outgoing = 587

  • SSL is not needed for both incoming or outgoing (uncheck)
  • Outgoing server does require Authentication
  • Authentication is password/clear text

Explicit SSL settings

Server name: mail.domainname.com (for both incoming and outgoing server)

Port numbers: incoming = 993 outgoing = 465

  • SSL is used both incoming or outgoing (check for both)
  • Outgoing server requires Authentication
  • Authentication with be password/clear text

Explicit TLS Settings

Server name: mail.domainname.com (for both incoming and outgoing server)

Port numbers: incoming = 143 outgoing = 587

If you use TLS with port 993 (incoming) and port 465 (outgoing) it will fail!

The username will always be the full email address and the password will be the password for that email address. These settings should allow Microsoft email settings to send or receive emails. Secure email is still always available through webmail at www.domainname.com/webmail or webmail.domainname.com (where the domain name.com is replaced with your domain name).

Hello BladeParker,

Thanks for the question. We did not know if there would be a fix, but after some research this past week, there was definitely a fix. The issue has to do with Microsoft not accepting the Email server's default certificate which is encrypted at a certain level. A fix was issued for this issue on Friday (May 15), so it should no longer be a problem. I will update the article and retire it to the archives shortly.

If you have any further questions or comments, please let us know.

Arnel C.
