  • MS outlook won't connect to Exchange if Wireless Card used

    Hello,

    I've been having this problem for a while now. When users are using their Wireless Cards to Connect to the internet instead of direct connection to MSOutlook 2007 which is connected to our exchange Server. Outlook sometimes won't open with a message that exchange is unavailable, and sometimes it keeps asking for the users Credentials over and over.

    Has anyone encounter something like this before?

    Thanks.

    is this inside the corporate network?
    how are the outlook profiles configured ? (mapi or Outlook Anywhere?)
    do the users only have wifi OR ethernet at any given time? (i've seen scenarios where users have persisted in using both wired and wireless, for god knows what reason, causing the computer to essentially become confused about which network to use)

      Sorry I forgot to tell you this is through VPN connection, We use the Wireless Internet Card mostly from home or when the Internet Service is down at our station, but mostly we are connected wired directly to the Network.

      When we use any acces point with the laptop's internal wireless card , there's no problem , the problem starts when we use our Internet Cards(Usb).

      How would I go to know if Profiles are MAPI or Outlook Anywhere ?

        Wired into the company network - works fine
        Accessing via external wireless network and VPN - works fine
        Accessing via cellular internet connection and VPN - doesn't work

        Is this correct?

            Do you have any other issues with the VPN over wireless? (can you access drives and other resources OK?)

                Everything else works(Slow but OK), except MSOutlook.

                My Cellular Provider is Claro, I'm in Puerto Rico.
                We use sprint too for wireless internet and the same problem occurs.

                  Check if you are using Mapi or Outlook Anywhere:
                  When Outlook is running, CTRL+ right click the task tray icon and select "Connection Status"
                  Check if it says TCP/IP or HTTPS - -the former is mapi
