Remote Outlook: Configuration



  • Yes, I Googled. What I found isn't helping.

    Have an Exchange server with remote users not on the domain. Trying to re-establish Outlook connectivity. I have the server address, etc, but for what ever reason it's not wanting to validate since it's not 'within the ' domain.

    I know it can be done,.. was done. But having some minor issues with the translation.

    (what I used:)

    Error: Action can not be completed. The connection to the Microsoft Exchange Server is unavailable....



  • First question, kind of outside of scope but may not have been considered, is... why are they off of the domain? Any reason that you don't fix the domain rather than fixing Outlook?



  • Right now @scottalanmiller, its to large of a issue to resolve. That is my desired goal.. but right now - I can only do so much.

    Are they domain computers? If so, fixing that problem should fix your Outlook problem.

    That said, when you are entering credentials for Outlook are you using domain\username or [email protected] (or [email protected], etc)?

    Are you sure that the issue is large? Typically AD joins are pretty trivial.



  • We use Office 365 so off domain Outlook is that standard there. It definitely works, but works smoothly when on domain.



  • AD joins are pretty trivial if your computer is still in the same network as the domain. Which it is not. The computer is 20 miles away from the AD on a non VPN network.

    This is still part of the networking / AD / Domain nightmare. We are looking to finish the primary (papered) OU deployment of O365, but this domain isn't at that point...

    That was assumed. VPNs are super easy, making remote machines "on domain" is very easy. Our entire network, for example, is on domain but located all over the world.



  • @g.jacobse so the computers at this remote location are stand alone machines at this time?

  • @scottalanmiller, I suppose what I need right NOW is just a band-aide.. I have so many more pressing and more serious issues it's unreal...



  • @Dashrender
    Yup
    Sad to say.. I didn't set it up,.. I just have to make it work (for now). It will be addressed.. It has to be. This isn't a way to operate a network.



  • Which version of Exchange are we talking about? I remember getting this to work with Exchange 2003 and 2010.

    Exchange 2003

    Give this a try:

    The registry modification steps listed below should be the same regardless of whether the computer is running XP, Vista, or 7. The registry modification MUST be done while logged in as the user who needs to use Outlook Anywhere.

    *Outlook 2003
    No registry modification is needed.

    Outlook 2007

    1. Click Start, click Run, type regedit in the Open box, and then click OK.
    2. Locate and then click the following subkey: HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\RPC.
    3. If the RPC key does not exist, you will need to create a new key within the Outlook folder.
    4. On the Edit menu, point to New, and then click DWORD Value.
    5. Type DefConnectOpts, and then press ENTER.
    6. Right-click DefConnectOpts, and then click Modify.
    7. In the Value data box, type 0, and then click OK.
    8. Exit Registry Editor.

    Outlook 2010

    1. Click Start, click Run, type regedit in the Open box, and then click OK.
    2. Locate and then click the following subkey: HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\RPC.
    3. If the RPC key does not exist, you will need to create a new key within the Outlook folder.
    4. On the Edit menu, point to New, and then click DWORD Value.
    5. Type DefConnectOpts, and then press ENTER.
    6. Right-click DefConnectOpts, and then click Modify.
    7. In the Value data box, type 0, and then click OK.
    8. Exit Registry Editor.

    For a New Mail Profile...
    The following steps must be performed with Outlook closed.

    1. In Control Panel, click Mail.
    2. Click Show Profiles.
    3. Add a new profile, and name it whatever you want.
    4. Once the Add New E-mail Account Wizard launches, choose the option to manually configure server settings or additional server types.
    5. Next, choose Microsoft Exchange as the E-mail Service. This may show up differently in different versions of Outlook, but select the option that mentions Microsoft Exchange.
    6. Enter mail.yourdomain.com (or whatever the public-facing DNS record for your mail server is) as the Microsoft Exchange server, and make sure the box labeled "Use Cached Exchange Mode" is checked.
    7. The User Name should be the full name of the user you are setting up.
    8. Click the More Settings button.
    9. Click the Connection tab.
    10. On the Connection tab, check the checkbox for Outlook Anywhere.
    11. Then, click the Exchange Proxy Settings button.
    12. Enter the public address of your mail server (DNS A-record or ip of your mail server) as the server name.
    13. Enter msstd:publicdnsoriphere as the proxy server address.
    14. Make sure the option for fast networks is not checked but the option for slow networks is checked. This will allow computers at our main site to connect to the Exchange server as they normally would but use Outlook Anywhere when off site.
    15. Change the authentication type to Basic Authentication.
    16. Click Ok and then Ok again to return to the Microsoft Exchange Settings screen.
    17. Click the Next button followed by Finish. If prompted for credentials, enter them in the form domain\username, and then enter your Windows password.

    For an existing Mail Profile...
    The following steps must be performed with Outlook closed.

    1. In Control Panel, click Mail.
    2. Click Show Profiles.
    3. Choose the profile you want to edit and click Properties.
    4. Click the E-mail Accounts button.
    5. Select the e-mail account in question, and click Change.
    6. This should open the Microsoft Exchange Settings menu.
    7. Click the More Settings button.
    8. Click the Connection tab.
    9. On the Connection tab, check the checkbox for Outlook Anywhere.
    10. Then, click the Exchange Proxy Settings button.
    11. Enter the public address of your mail server (DNS A-record or ip of your mail server) as the server name.
    12. Enter msstd:publicdnsoriphere as the proxy server address.
    13. Make sure the option for fast networks is not checked but the option for slow networks is checked. This will allow computers at our main site to connect to the Exchange server as they normally would but use Outlook Anywhere when off site.
    14. Change the authentication type to Basic Authentication.
    15. Click Ok and then Ok again to return to the Microsoft Exchange Settings screen.
    16. Click the Next button followed by Finish. If prompted for credentials, enter them in the form domain\username, and then enter your Windows password.

    Now, if all of this still does not work, try opening a VPN connection from the site where the machine is to the site where the mail server is, opening Outlook, logging in, letting the mailbox pull down from the server for the first time, and closing the VPN and logging back into Outlook. It should work after that.
