“Microsoft Outlook has encountered a problem and needs to close. We are sorry for the inconvenience”. This error message may appear when you try to open Microsoft Outlook. Also, the program may refuse to open up without showing any error message or with a different one. There are a number of reasons that prevent it from opening up. You can also find here Why Outlook is closing randomly ?
Let me discuss here how you can fix this Microsoft Outlook problem. Check the steps below:
1. Close Outlook if it is running. Close any error message that is appearing on the screen. Exit MSN or Windows Messenger if running. Click the Start button and click Search. Type ‘outcmd.dat’ (without quotes) in the search box, select C: drive as the directory to look in to and hit the Search button. Windows 7 and Vista users can use the Start Search bar to type and search for the ‘outcmd.dat’ file.
2. When done, right-click the outcmd.dat file and select Rename. Change the file’s name. Exit the Search Results window. Now reopen Microsoft Outlook. It should open up fine. If it still does not open, go back looking for the outcmd.dat file in the Search Results window. Right-click the file and select Delete. If prompted, confirm the action by clicking the Yes button. lose the window and reopen Outlook. It should open fine.
OUTCMD.DAT is a small file that stores the custom changes you make to your Outlook toolbar buttons. Since malware or virus infections often target toolbar to slip into your computer, they add toolbars or add-ins to this file, making it corrupt. Also, a temporary glitch can cause this file to become corrupted. If Outlook starts working fine after renaming the file, you can customize your Outlook toolbar buttons again. Otherwise, delete the file and then re-customize your toolbar buttons.
3. If you are using Windows 7 with the Outlook 2010 version and receive “Cannot start Microsoft Outlook. Unable to open the Outlook window. The set folders could not be opened. The server is not available. Contact your administrator if this condition persists”, check this method. Click the Start button> All Programs> Accessories> Command Prompt. If you do not see Command Prompt anywhere in programs, type ‘command’ (without quotes) in the Start Search type, and look in the search results.
4. In the Command Prompt window, type ‘C:\Program Files\Microsoft Office\Office 14\Outlook.exe” /resetnavpane’ (without quotes) and hit Enter. The command assumes that your Office program resides in Programs Files in the C: drive. If it resides in a different location, change the path accordingly. Exit the Command Prompt window. Open Outlook and check back, it should work fine. The command removes and recreates the navigation panel for your Outlook profile.
5. Disable the add-ins that you no longer use. Click the Start button> Run. Type ‘outlook.exe /safe’ (without quotes) and hit Enter to start Outlook in Safe Mode. When in Outlook, click the Tools tab> select Trust Center. Click Add-ins in the left hand panel of Trust Center. Look at the bottom of the window beside Manage. Also find here how to disable/remove Microsoft Outlook 2010 add-ins.
6. If COM Add-ins is not selected beside Manage, click the drop-down menu and select it. Hit the GO button to get in the COM Add-ins window. Look for the unnecessary add-ins and uncheck the box beside it, and then hit the OK button. If you want to remove an add-in, just select it, and hit the Remove button. The add-in will be removed. Exit Trust Center, close Outlook and reopen it. It will open up fine in the normal mode.
***If none of the above mentioned methods works, open Outlook in Safe Mode and delete your existing email profile. Create a new profile and restart Outlook normally.
