 Some of the Reasons Why Office Outlook May Not Start

Corrupt Outlook Profile

Cause

The profile (.pst or .ost file) may be corrupted, and may have to be deleted and re-created.

Resolution

For information about how to troubleshoot the .pst and .ost files, see: this Microsoft Website.

No Data Connection

Cause

There is no Internet or Local Area Network connection.

Resolution

You can test your connection using Telnet. For more information about how to use Telnet to test communications, see

How to Use Telnet to Test SMTP Communication.

Antivirus Software

Cause

Antivirus scanning is active. Your antivirus software may lock you out of Outlook if it determines the program has become infected with malicious software.

Resolution

For information about your antivirus software and why it may prevent Outlook 2007 or Outlook 2003 from starting, review your antivirus software user help.

Locked Office Outlook Files

Cause

The Outlook executable file (Outlook.exe) or the Outlook .pst or .ost file is locked.

Resolution

Check the properties for these files, and verify that they are not read only.

The default location for the .pst and .ost files is: C:\Users\<User_name>\AppData\Local\Microsoft\Outlook\.

The default location for the Outlook.exe file is: C:\Program Files\Microsoft Office\Office12\.

Note

Some of these are invisible files. You may have to change the system settings to see them and use Advanced search settings to find them.

Third-Party Add-Ins Keep Office Outlook From Starting

Cause

Third-party add-ins are causing problems that are keeping Outlook from starting.

Resolution

To test whether this is the problem, follow these steps to start Outlook in safe mode.

To start Office Outlook in safe mode

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

2.     Type Outlook in the text box, and then click OK.

If an add-in is causing the problem, you are prompted to disable the add-in.

Corrupt Office Outlook Program Files After an Upgrade

Cause

If Outlook was upgraded from an earlier version, some program files may have become corrupted.

 

Resolution

If the files in this list are present, they can be safely deleted or renamed. Outlook will re-create all files except Outcmd.dat without loss of data or settings. Outcmd.dat saves customized toolbar settings, and these will have to be reapplied.

• Extend.dat – Located in C:\Documents and Settings\<username>\Local Settings\Application Data\Microsoft\Outlook\.
• Frmcache.dat – Located in C:\Documents and Settings\<username>\Application Data\Microsoft\Forms\.
• Views.dat – Located in C:\Documents and Settings\<username>\Application Data\Microsoft\Outlook\.
• Outcmd.dat – Located in C:\Documents and Settings\<username>\Application Data\Microsoft\Outlook\.

Note

Some of these are invisible files. You may have to change the system settings to see them and use Advanced search settings to find them.

Outlook Setup Add-In on Dell Laptops

Cause

On Dell portable computers that have MediaDirect, the Outlook setup add-in Cyberlink slows down Outlook and turns all meeting requests into recurring meeting requests.

Resolution

The Cyberlink add-in has to be uninstalled.

To remove the MediaDirect Cyberlink add-in

1.     Open Office Outlook 2007 or Outlook 2003.

2.     On the Tools menu, click Trust Center, and then click Add-ins.

3.     In the Manage list, select COM Add-ins, and then click OK.

4.     Clear the check box for the Cyberlink add-in, and then close the dialog box.

MSVCR80.dll Missing Messages

Cause

These error messages are common with software installed by original equipment manufacturers and are caused by an add-in. The add-in puts an Outlook.exe manifest file in the Outlook.exe installation folder, which overwrites the Outlook executable and causes the installer for the add-in to run.

Resolution

You should contact the manufacturer of your equipment for resolution of this issue. You may be required to re-install Office Outlook 2007 or Outlook 2003 to resolve this issue.

Unregistered Office Outlook Files

Cause

Two important Outlook files have been incorrectly registered.

Resolution

Use the following procedure to fix this problem.

To repair unregistered Office Outlook files

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

2.     Type regsvr32 OLE32.DLL in the Run box, and then click OK.

3.     When you see a message stating that the command was successful, click OK.

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

5.     Type regsvr32 INETCOMM.DLL in the Run box, and then click OK.

6.     When you see a message stating that the command was successful, click OK.

Issues With a Cisco VPN Client

Cause

This can occur when you have a computer that is running the 64-bit edition of Windows Vista Ultimate with a new installation of Outlook and settings that were transferred from a computer running Windows XP.

Resolution

To correct this problem, Cisco recommends upgrading to a Cisco AnyConnect Client.

Note

Because the settings were transferred from Windows XP, they are located in the Control Panel in the 32-bit program folder.

Interference From Third-Party PDA Software

Cause

Third-party personal-digital-assistant software (Palm, Blackberry, etc.) is interfering with Office Outlook 2007 or Outlook 2003.

Resolution

To resolve issues with third-party software, ask your service administrator for assistance, and see the user help for your third-party software.

 Office Outlook Starts But Will Not Connect

Symptoms

When you try to connect Office Outlook 2007 or Outlook 2003 to Exchange Server, you may experience any of the following symptoms:

• If your Outlook profile has been automatically configured, you may receive the following error message:
  
  The action cannot be completed. The connection to the Microsoft Exchange Server is unavailable. Your network adapter does not have a default gateway.
• If your Outlook profile has been manually configured, you may receive the following error message:
  
  Your Microsoft Exchange Server is unavailable.
  
  For example, this error may occur when you have an existing profile that was previously connected to an Exchange Server, and then you lose the setting for your default gateway. In this scenario, if you click Check Name in the E-mail Accounts dialog box to verify your settings, you may receive the following error message:
  
  Outlook cannot log on. Verify that you are connected to the network and are using the correct server and mailbox name. The connection to the Microsoft Exchange Server is unavailable. Your network adapter does not have a default gateway.

Cause

This problem may occur if the computer with the Office Outlook client does not have a default gateway configured.

Resolution

To resolve issues with default gateway configuration, follow this procedure: The default gateway is not configured.

Caution

The solution referenced in this procedure requires modifying the system registry using Registry Editor (regedit). If you use regedit incorrectly, you may cause serious problems that may result in the loss of data and may require that you reinstall the operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk. If you are unfamiliar with making changes to your computer’s registry, ask your service administrator or other computer professional to help avoid problems.
