What is Outlook?

Outlook is an email and calendar program developed by Microsoft. It was initially released in 1998 as part of the Microsoft Office suite. The app allows users to manage their emails, calendars, contacts, tasks, notes, and more. It also provides a powerful set of tools for organizing and tracking data.

With Outlook, users can schedule meetings, keep track of appointments, send out messages to contacts within their organization or external addresses, store data in folders and search through it quickly. Also, it integrates with many other applications like SharePoint and Dynamics 365 to provide a comprehensive experience for enterprise users.

The platform also offers automated filters and rules that help organize incoming emails and keeps all your account information secure with built-in security features such as two-factor authentication. Outlook is essential for staying organized, efficient and productive in any business or personal environment.

Perform System Restore

If Microsoft Outlook is constantly popping up with a message of opening in safe mode, you need to return to normal mode. To launch Outlook out of safe mode, sometimes you need to use the system restore.

Restoring the device to the last working condition where Outlook was doing well can resolve the safe mode error, and this could only be performed if you create restore points regularly. Here are the steps to follow:

Step 1: Launch system restore from the windows main menu. In the main menu’s search bar, type system restore and double-click the option to launch it.

Disable Windows Search Service

Disabling the Windows Search Service can help prevent Outlook from opening in safe mode. This is because when this service is disabled, Outlook cannot access the indexing catalog of archived emails, making it challenging to launch.

When this service is disabled, Outlook can only access the local PST file instead of having access to all email accounts, preventing it from automatically launching in safe mode. To disable the Windows Search Service, head over to your computer’s Services panel and stop the running service. It should no longer interfere with Outlook’s performance or cause any issues. Here is how you can fix Outlook.

Step 1: Launch the Run utility with the keyboard’s windows key+ R shortcut keys.

Step 2: In the run command box, type services.msc and click ok to continue.

run services msc command

 Step 3: In the services menu, navigate to windows search and click it. Then, select stop the service from the left pane.

Use resetnavpane Command

For launching Microsoft outlook in normal mode, sometimes the ongoing issue between the Windows search service and outlook application won’t allow it to open. This causes an error, i.e., Outlook is in safe mode. The issue can be fixed by using the command prompt action. Here is how you can fix Outlook.

Step 1: Launch the Run utility with the keyboard’s windows key+ R shortcut keys.

Step 2: In the run dialog box, type outlook.exe /resetnavpane and click ok to complete the action. It will start Outlook in normal mode.

These additional pieces of software can interact directly with Microsoft applications, so if one is not working correctly, it could cause Outlook to open in safe mode. Here are the steps to follow:

Step 1: Launch outlook from Windows’ main menu. Type outlook in the taskbar’s search box and double-click the option to launch the menu.

Step 2: In the Outlook window, navigate to the file option in the header menu. Click the file and select options in the next window.
