Outlook Auto Account Setup: Encrypted Connection not available

Slipstick Systems

› Outlook › Configure and Maintain › Outlook Auto Account Setup: Encrypted Connection not available

Last reviewed on March 8, 2017     86 Comments

With the introduction of two-factor authorization since the original date of this article, there is a second (and becoming more common) cause of this error: Outlook needs the app password, as it will not currently bring up the second authorization screen.

The message that comes up when Outlook can't set up an encrypted connection automatically caught a couple of users off guard this week. After calling their mail provider to verify the account supports encryption, they asked me what was wrong with Outlook.

An encrypted connection to your mail server is not available. Click next to attempt using an unencrypted connection.

This message doesn't mean that the mail server doesn't support encryption, it just means Outlook's Auto Account Setup can't determine the correct settings to use. This is caused by incomplete or missing autodiscover records in DNS. As a result, you'll need the account up manually if you want to use encryption.

When this message comes up, click Back, select Manually configure server settings then click Next.

You'll need to enter your account information and server names then click More Settings and configure your SSL or TLS settings on the Advanced tab.

is there a need to mention incoming and ougoing server information in this blog?
and the screenshot that you attached is not the window that opens when you select manual configuration for setting up Outlook.

Did you notice the article was written in 2017? There have been a few new releases of MS Office since then, so yes, things may look slightly different.

I am having this problem too. I've manually entered the settings. I'm using MS Outlook 2007, attached to an AOL mail account. I receive and send email using that account from all my other devices, which suggests the problem is in my Outlook app or my PC. I can use the online AOL account. I've run "Repair email account," tried turning off the Windows firewall, and other things. Any suggestions?

I don't know if this will help, but I finally found that the problem was not on the desktop side, but on the server/hosting side. I use exchange server, hosted by Microsoft, and had to turn off "Security Defaults" in my Office portal. Once I had done that, Outlook stopped asking repeatedly for the password. I guess the problem might be the same with other email hosts as well, just try to find out if there is a setting somewhere on gmail/yahoo/outlook or whatever you are using. Gmail have a "support for less secure apps" setting that caused some trouble if it was enabled.

To fix my Exhange security settings, I just did the "Turn Security defaults on or off" part of https://docs.microsoft.com/en-us/microsoft-365/admin/security-and-compliance/set-up-multi-factor-authentication?view=o365-worldwide

Hi there,

My security defaults are turned off in AAD but still the issue persists. Also, the user in getting is prompted by " Help us protect your account "every time trying to login to Azure portal. Have troubleshooted with re configuring MFA to Microsoft authenticator app and SMS but seems to have not fixed the issue.

Typically, IMAP is 993 and 465 or 587 for SMTP but you need to check with your email provider to verify. Most have this information on their Support pages.

Two days ago, our "alifrant@yahoo.com" login credentials suddenly started getting "rejected by the server." None of the suggested fixes makes any difference. Tried various things for two days, with no luck. We're going to install Thunderbird and see if that will work for us in place of Outlook.
