Can You Use Outlook in Safe Mode?
Even if you’ve been having problems with Outlook, it opens normally in safe mode because it starts without extensions or custom toolbar settings and disables the Reading Pane. These items are common sources of problems, so, after using safe mode, investigate those parts of the program to see what’s preventing it from opening correctly.
How to Start Outlook in Safe Mode Using the Outlook Shortcut
To open Outlook in safe mode, press and hold the Ctrl key, then select the Outlook shortcut. In the warning dialog box that appears, confirm that you want to open Outlook in safe mode by selecting Yes.
Open Outlook in Safe Mode From the Command Line
Another way to open Outlook in safe mode is to use the Command Prompt:
How to Create an Outlook Safe Mode Shortcut
If you want to create a fast way to open Outlook in safe mode without going through these steps again, make an Outlook safe mode shortcut.
You can tell if Outlook is running in safe mode if the title of the program says (Safe Mode).
To disable safe mode in Outlook, double-click or double-tap the regular Outlook shortcut you always use. Safe mode isn’t enabled unless you use one of the methods described on this page.
Command Prompt Method
You need to know the full path to the Outlook.exe file before you can start Outlook in safe mode using Command Prompt. The path of the file depends on the version of Outlook and whether it’s the 32-bit or 64-bit edition. If you don’t know what to type in Command Prompt, see the next section below. Otherwise, open Command Prompt and type the following command, replacing this path with the one to your Outlook.exe file: After you make the necessary changes in Outlook, close the program and reopen it with the normal shortcut you use to open Outlook. As long as you don’t open it with one of the methods described above, it will always start normally (not in safe mode).
Outlook.exe Location
There are a couple of ways to find where Outlook.exe is stored. The easiest is to copy the command as you see it below and paste it into Command Prompt. You need to know which version of Outlook you have for this to work. Another way that doesn’t require you to know which version of Outlook is installed is to search your computer for outlook.exe. You can do that with the built-in search tool in Windows or download and use a third-party program like Everything.
