Error message when you try to start Microsoft Outlook after you install the Microsoft Dynamics CRM client for Outlook: “There is a problem communicating with the Microsoft CRM Server”

Cause 1

This issue occurs if you used the IP address of the Microsoft Dynamics CRM server instead of the DNS name during the Microsoft Dynamics CRM client for Outlook installation. An example of a DNS name is http://crm.

Cause 2

This issue occurs because the user who is accessing the Microsoft Dynamics CRM client for Outlook is in Restricted accessmode.

Cause 3

This issue occurs because the .srf extension mapping of the MSCRMServices service is missing in Microsoft Dynamics CRM.

Cause 4

This issue occurs because a stored user name and a stored password are present on the client computer. If you change your own password on the computer, the password is not updated.

Cause 5

This issue may occur because the Exchange System Manager and Microsoft Outlook are installed on the same computer. We do not support the installation of both programs on the same computer. This situation can cause errors when Exchange and the Outlook versions of MAPI run at the same time.

Cause 6

This issue can be caused by a VPN connection not being configured to send the domain name along with the user login when connecting to the Microsoft Dynamics CRM server.

Resolution 1

To resolve this issue,  use one of the following methods.

Method 1: Add the IP address of the Microsoft CRM server to the Trusted Sites list of the Local intranet zone on the computer that is running the Microsoft Dynamics CRM client for Outlook

  1. Start Internet Explorer.
  2. On the  Tools menu, click Internet Options.
  3. Click the Security tab.
  4. Click Local intranet, click Sites, and then click Advanced.
  5. In the Add this Web site to the zone box, type the IP address of the Microsoft CRM server, and then click OK three times.
  6. Restart Microsoft Outlook.

Method 2: Verify that the correct URL for the Microsoft CRM server is in the ServerURL and WebAppUrl registry keys

  1. Click Start, click Run, type regedit, and then click OK.
  2. Locate the following subkey:
    HKEY_CURRENT_USER\Software\Microsoft\MSCRMClient
  3. Verify that the URL listed in the
    ServerURL

    and the

    WebAppUrl

    registry keys contains the correct URL for the Microsoft CRM server.
    An example of a URL in the

    ServerURL

    registry key is as follows:

    http://servername:5555/mscrmservices

    An example of a URL in the

    WebAPPUrl

    registry key is as follows:

    http://servername:5555

    Notes

    • servername is the name of the Microsoft CRM server and 5555 is the port number on which Microsoft CRM is installed.
    • If Microsoft CRM is installed on port 80, you do not need the port number listed in the registry keys.
