An Encrypted Connection to Your Mail Server is Not Available

When Exchange Server 2010 has been introduced to an existing Exchange 2003 organization some Outlook 2010 clients may report the following error when setting up a new mail profile.

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

After trying an unencrypted connection Outlook fails to connect to the user’s mailbox.

This will occur for Outlook 2010 users who still have mailboxes on an Exchange 2003 server, however it should only occur when a new profile is being created, not every time they launch Outlook.

You can create the profile by choosing the “Manually configure server settings” option instead.

      I had the same problem when I want to make an account in MS Outlook 10. I got a solution that you must get an “APPLICATION SPECIFIC PASSWORD” from your google setting. And than use that new passport only for one tine while entering your email address and password in Outlook.

      That password contains 16 alphabets. And also keep that password in safe place for any other application.

      Gmail Setting ===> Account (Tab) ===> Other Google Account Setting ===> Go to Security (Tab) ===> Click on App Password “Setting” ====> Enter your regular password ====> Enter the name of Application f.e.x “OUTLOOK” and than Click on “Generate Password ====> your will get a password like “ABCD EFGH IJKL MNOP”. =====> now click DONE.

      That 16 alphabet password will be your APPLICATION SPECIFIC PASSWORD.

      Go to OUTLOOK===> ADD NEW ACCOUNT ====> enter your NAME, EMAIL and that 16 ALPHABET PASSWORD instead of your regular password of your Email ===> Click NEXT.

    hi there Paul,
    I am having this problem with outlook 2010 and Exchange Server 2010!!! which is a fresh install on Windows Server 2008 R2.Besides I am having certificates issues and don’t want to buy certificates because the exchange system is for internal use only and I am running a ONE mailbox with popcon to grab pop3 messages online.

    did you even bother testing this?

    manual configuration results in:

    The action connot be completed. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action.

    all mailboxes have been moved to the 2010 server.

      Hi Jason,

      Did I even bother testing this? I’m not sure how to respond to that.

      Yes I tested it, that’s why I posted the solution. It deals with the specific scenario described in the post:

      - Exchange 2010 installed into existing Exchange 2003 org
      - Outlook 2010 client creating new Outlook profile for a mailbox still on Exchange 2003

      If you’ve already moved the mailboxes to Exchange 2010 you may have a different underlying issue that presents as the same error. If you’d like to describe your scenario in more detail, including anything you’ve already checked, there might be some more suggestions I can offer.

        Hi Paul,

        I’m having the same problem except I’m not computer savy enough to have thought about even bothering to testing this. Before I even read your response I was thinking what a cocky POS answer Jason gave. Of course this does not help me but just wanted to say that you took the high road.

        I’m wondering if I reinstall exchange 2003 and use my old settings so I can access my Outlook.

        Thanks,
        Sarah

    Hi Paul — or anyone who can help —
    We have two email addresses for our company, and set them both up to work with Outlook 2007. This has worked out fine on one of our computers but the other one will not receive mail from the most recent account. It says “an encrypted connection to your mail server is not available.” What are some possible causes of this?
    Thank you so much,
    Erin

    I finally solved the problem by configuring my gmail account in Outlook 2007 (An encrypted connection to your mail server is not available. Click Next to attempt using an unencrypted connection.), everything works with what Clay said on January 12, 2012 at 11:35 am, follow the steps in “create an application-specific password” at this link

    Dear All,

    Just in case you are getting this problem post enabling “2-step verification” on your gmail account then its worth reading about “Application-specific passwords” .

    Basically either get rid of “2-step verification” or simply generate a password for your email client called “Application-specific passwords”. This password you should be using to connect to gmail via email client.

    cheers

    Hi,

    I have Outlook 2010 and Window 8. When outlook mail was trying to connect to server. There would be a pop-up screen to enter password. But it was strange that it popped up many times. And then it appeared An encrypted connection to your server is not available. Then I tried unencrypted connection, the result was also the same.

    Is it possible that the server of outlook mail doesn’t support Win 8?

    I ahve an issue with this error.

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

    worked yesterday, guys gets to work today and gets asked for passwords from both his pcs, nat’d to the same IP. set him up with a new mail account in a differrent domain to test and that has the same issue, auto discover works and so does owa to both accounts.

    no one else is getting the issue in the same office all on the new hosted exchange as he is?

    Any ideas is it encryption? when we remove everything and start again we cannot get even the old one to work !

    We’re a small business. For our regular employees, we’ve converted everyone to Office 365 and migrated our 3rd party hosted IMAP mail server over to MS hosted exchange mail servers. Everything is working fine, however, we have a couple part time employees who need to access our mail system from home using desktop versions of Outlook 2007. We “bought” Exchange licenses for everyone, but when we go to add exchange based accounts to their Outlook, they’re getting the “encrypted connection not available” message. We’ve tried the unencrypted route with no success. Any suggestions?

    • says

      I’d suggest an Outlook upgrade for them. Or use Outlook Web App (webmail) only.

      http://technet.microsoft.com/en-us/library/office-365-system-requirements.aspx

      “Office 365 is not designed to work with Office 2007 because Office 2007 left mainstream support on October 12, 2012. Office 365 does not offer code fixes to resolve problems you encounter when using the service with Office 2007. You should expect the quality of the user experience to diminish over time, and many new Office 365 experiences will not work at all. We recommend that you upgrade as soon as possible to Office 365 ProPlus or Office Professional Plus 2013 for the best experience with Office 365.”
