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.

    I have done what you said but still having trouble to received and re-create my account as I deleted it and tried to re-create it. Now, I cannot create it on outlook.

      Do you get any error messages when you try to send? Who is your email host?

  2. Jessica says

    thanks for the quick reply! yes i get the error message "None of your e-mail accounts could send to this recipient." even when i try different addresses. it worked fine before i rebooted my computer

    • Diane Poremsky says

      is this with your Hotmail address? It may be a problem on their end - I know they are having issues the last few hours.

  3. Jessica says

    no this is through webmail ( or it won't send through this to anyone

    • Diane Poremsky says

      Are you authenticating with the server? Go into File, Account Settings, double click on the account and then more Settings. Check the outgoing server tab. In Outlook 2007 and older, Accounts is on the Tools menu.

    Hi Diane, I tried everything taking every step over again reading everything on google. I downloaded hotfix and it came back to me saying a add-in had an error. once i disabled this it worked fine! Thank you for your help!

    • Diane Poremsky says

      Thanks for the update. Do you know which addin was the problem? It may help other who have a similar problem.

    Jessica or Diane Poremsky; I've been reading through your conversations and I have been having the same issue with sending e-mails through outlook. I use Microsoft Outlook 2010 for my internet e-mails and if you could tell me what add-in you had to disable, I would GREATLY appreciate it.

    • Diane Poremsky says

      The error message should tell you want addin (it would vary with each person), but you could try disabling all addins in File, Options, Addins - click Go at the bottom and uncheck non-Microsoft addins.

    Dear Diane, I have the problem with auto account setup the auto filling not working and users have to type in manually all settings.

    • Diane Poremsky says

      What type of email accounts do you use? The usual cause of this problem is no autodiscovery file configured in Exchange and Outlook can't get the correct servers to use from DNS records.


    i am unable to configure a gmail account in outlook.

    My problem is that it is only happening on a couple of computers when setting up a new user. One of those machines has been used before and had no problems with a previous user, but the newest version of Office 2013 seems to break. But other machines (75 or so users) are working just fine. (Windows 7, Office 2013)

    I am not able to send emails. on very bottom right it is saying sending/receiving error. I am using outlook 2010. Then when I go into account settings and repair it is saying the unencrypted deal everyone is talking aboul

    • Diane PoremskyDiane Poremsky says

      Double click on the send/receive error in the bottom right to open the send and receive dialog then check the errors tab - what is the error?

    Hi Diane,

    Ive been researching this issue for a client on Outlook 2007/2010. I have received both errors in a loop scenario,

    With default port settings for both POP and IMAP I get the error:

    "Send test e-mail message: None of the authentication methods supported by this client are supported by your server."
    (which occurs when outgoing server tab > "Use same settings as my oncoming mail server" box is checked)


    "554 5.7.1"
    (which occurs when outgoing server tab > "Use same settings as my oncoming mail server" box is NOT checked, so when any other option is checked instead)

    There are so many simple solutions that work for most but I still can't get to the bottom of it...

    Ive tried all the solutions that have worked for other people such as trying each variation of the outgoing server options on both POP and IMAP, but also:

    On POP version of the account
    1) Changing encryption types but my server ( wont allow SSL or TSL anyways. = encryption type not supported by server error
    2) Changing outgoing server port to 587 (with no encryption type as server wont allow it as above) = authentication methods not supported by server error

    On IMAP version of the account
    1) Changing incoming and outgoing port numbers to 993(SSL) and 587(No encryption) respectively = authentication methods not supported by server error

    I feel if there was some way to easily contact the mail/server provider, they could simply authorise any of the encryption ports/methods such as port 587 / SSL or TSL and itd be fixed?

    Anyways Ive exhausted myself after trying for a day looking at every solution online. I keep running into issues with outlook and the support is quite hard to find.

    I hope you can help me,

      Are you using the correct server names?
      POP3 mail
      SMTP mail

      if they don't support encryption, it should work with the standard ports of 110 and 25.

    If I try manually entering the settings because the autodiscover from DNS does not work how do I know which settings I should use? Where can I find these settings? I can add emails perfectly fine unencrypted but not encrypted. Would appreciate a swift response. Thanks

    • Diane PoremskyDiane Poremsky says

      you'll get the server information from your mail host. You can let outlook set it up unencrypted then go in and change the server ports and ssl information.

    Hi Dianne, I am wondering if you can help me. I have three email addresses which I use out of my outlook account, however one of them has stopped being able to send emails. I have gone to my service provider and can send and receive emails directly from their site but not via outlook. I get the error message "Outlook cannot connect to your outgoing (SMTP) e-mail server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP)." I have gone in and manually changed the Outgoing Server (SMTP) to 587 and the encryption connection to None, and when I do this the emails will send. When I turn it back to my original outgoing server number and the encryption back to SSL it will not work. I then discovered when I close outlook and reopen, it has reset the Outgoing server (SMTP) to 25 and the encryption to None all on its own. I am a little confused as to why it is just happening with one of my accounts and not all of them. Do you have any suggestions?


    • Diane PoremskyDiane Poremsky says

      It's possible Outlook is getting the server info from the autodiscover file... when you change the setting, make sure you use the OK button to close all of the dialogs, not the X after Ok'ing the port change. If you close the dialog using the X, the change only applies to the current session.
