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.

    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.
    My error is as : http://exchangeengine.wordpress.com/2010/03/18/getting-autodiscover-warning-message-in-outlook-2007-domain-joined-workstations/.
    Thank you for help!!!!

    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

    I am haing Exchange 2010 in my environment & using outlook 2010 where i faced the subject issue “An Encrypted Connection to Your Mail Server is Not Available”.

    I found out that the user for whom i was trying to configure outlook was LOCKED in AD. I unlocked his account & the problem was resolved.

    I noticed you needed to enable imap in your gmail settings using the web.

    Another tip is to go http://www.google.com/accounts/DisplayUnlockCaptcha and login using your credentials. After doing that then go back and try your Outlook connection to your gmail account.
