The error means that Outlook was not able to open properly. This could be due to a number of things, including a problem with loading your profile, add-ons, or configuration files. We’ll need to take a closer look to see what’s causing the issue.
- Start Outlook in Safe Mode
- Disable Add-ins
- Repair data file
- Create a new Outlook profile.
First, check to see if your internet connection is working. If it is, try restarting your computer. If that doesn’t work, try restarting your router. If that doesn’t work, try resetting your modem. If that doesn’t work, try contacting your ISP.
1] Start Outlook in Safe Mode
When you get the Outlook Safe Mode prompt, it is generally a good idea to choose “Yes”. Doing so will launch Outlook in safe mode, which disables anything that is not necessary. If Outlook works fine in this mode, then your problem could be with add-ins, profile, and other configuration.
If you want to manually start Outlook in safe mode, first close it, and then type the following command and press Enter:
Choose ProfilesIt will then prompt you with Choose Profiles. Select the default profile, and then click ok. If you had set up a password, then make sure to provide that.
2] Disable Add-ins
In order to find the problem, you can either disable everything and then turn it on one by one, or you can disable one and relaunch Outlook to check if everything is working fine.
- To open the Outlook Options window, click File > Options.
- In the Add-ins section, you will see a list of all the available Add-ins.
- At the bottom of this section, click on the Manage Comm Ad-ins button.
- Here, you can deselect the add-ons you want to disable and relaunch Outlook.
3] Repair data file
If you’re having trouble with your Outlook data file, Microsoft Office offers an in-house tool called SCANPST.EXE. This program can scan, diagnose, and repair errors in your PST file. It’s a good idea to check if the issue is due to an error in your PST file before taking any other troubleshooting steps. The program is usually available in the following path.
- Outlook 2019: C:\Program Files (x86)\Microsoft Office\root\Office16
- Outlook 2016: C:\Program Files (x86)\Microsoft Office\root\Office16
- Outlook 2013: C:\Program Files (x86)\Microsoft Office\Office15
- Outlook 2010: C:\Program Files (x86)\Microsoft Office\Office14
- Outlook 2007: C:\Program Files (x86)\Microsoft Office\Office12
Close the Outlook application, and make sure that it’s not there using the Task Manager. Done that follow the steps as below:
- To launch SCANPST.EXE, double click on it.
- Click on the “browse” button, and select the Outlook Data File (.pst).
- Click on the Start button.
- You’ll be notified if there’s an error and given the option to repair it.
- Click the button and let the process do its work.
Relaunch Outlook after the repair is complete to check if the message still appears.
4] Create a new Outlook profile
The best idea is to create a new Outlook Profile if nothing else works. If the profile for some reason is misconfigured and you are not able to repair it, then creating a new one will help you out.
- Click on File, then Info. Next, click on Account Settings, and finally Manage Profiles.
- Click on the “Show Profiles” button to open the Mail window.
- Click on the Add button, and name your profile.
- You will need to add your email account here and then sync all your emails.
Creating a new profile isn’t as friendly as you need to add everything again. That’s why we only recommend using it when you don’t have anything left.
