Enabling Outlook in Safe Mode
Microsoft Outlook 2007 may crash when you perform a particular task or when you quit it. You will not be able to identify the reason for the crash, as the problem does not arise frequently. In such a situation, the best solution is to start Outlook in Safe mode.
What is Safe Mode?
Launching Outlook in Safe Mode helps you to fix Outlook issues like “Cannot start Outlook.”In Safe mode, various settings that you have enabled will not load while starting Outlook. On the other hand, it launches in the factory mode without loading the additional plug-ins as well as the reading pane. Therefore, it allows users to use Outlook in a safer way when met with launch issues. You can enable the Safe Mode in two ways as given below.
Preset Safe Mode
In this case, the Outlook application will transfer to this mode automatically once an issue is identified. It will correct the issue by its own thereby enabling the program to function smoothly. Once Outlook is opened, Office will look for problems like add-ins, extension issues, or invalid registry files. If the program is unable to launch next time, automated Safe Mode will be enabled to disable the problem-creating entries. Once those are disabled, you should be able to launch the application normally. You can exit this mode by closing and re-launching the application again.
Manual Safe Mode

You can launch the Safe Mode manually also by running a command. Click on the “Start” button and choose “Run.” Enter the command “outlook.exe/safe” in the “Run”window and hit “OK.”
Comparison of Safe Mode against Normal Mode
You will be able to use Outlook with limited features in Safe Mode only. Once this mode is enabled, items like add-ins, extensions and other customized settings will be disabled and only the dialog box of the corresponding parts will be offered to you. Whereas, all the parts associated with Outlook will be operating in normal mode and therefore the choice to avoid or un-select respective items is disabled. Launching in Safe Mode allows you to resolve Outlook issues like “Borland Database Engine Not Installed” or “Cannot start Outlook.” On the other hand, it is not possible to fix these issues in normal mode.
You should be able to fix almost all Outlook issues in Safe Mode. Outlook help will also guide you to familiarize the Outlook functionalities so that you can resolve these basic Outlook issues.
