When you use Microsoft Office Outlook, and you have the Microsoft Dynamics CRM for Outlook client installed, the CRM preview/form region at the bottom of the window displays no information.

Symptoms

This issue may be caused by one of the following conditions.

Cause 1: An earlier version of Microsoft Office left behind references to an older Object Library (OLB) file. This typically includes earlier versions of the Primary Interop Assemblies.

Cause 2: The user profile temp directory contains more than 65,535 files. Outlook uses temporary files for form region storage. However, if the user's temp directory contains more than 65,535 files, Outlook cannot initialize the form region.

Cause

Resolution for Cause 1

Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

322756 How to back up and restore the registry in Windows

  1. Click Start, click All Programs, click Accessories, and then click Run.

  2. In the Run dialog box, enter regedit, and then click OK.

  3. In Registry Editor, locate the following hive:

    HKEY_CLASSES_ROOT\TypeLib\{00062FFF-0000-0000-C000-000000000046}\9.3

  4. Locate the PrimaryInteropAssemblyName string value, and then determine the version, as seen in the bolded element in the following example:

    PrimaryInteropAssemblyName"="Microsoft.Office.Interop.Outlook, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71E9BCE111E9429C

If the version is 12.0.0.0, you must delete the 9.3 folder hive, as this corresponds to the 2007 Microsoft Office system.

Resolution for Cause 2

  1. Click Start, click All Programs, click Accessories, and then click Run.

  2. In the Run dialog box, enter %localappdata%, and then click OK.

  3. Open the Temp folder.
