You don’t lose your emails as Outlook re-syncs your account items when you add your account. Here is the three-step procedure on how to do that.
Step 1: Find the Current Outlook Data File Location
- Open Outlook and navigate to File > Account Settings > Account Settings.
- Access the Data Files tab and note your data file’s path.
Step 2: Create a New Outlook Profile
- Open the Start menu, find Control Panel, and launch the utility.
- Select User Accounts in Control Panel.
- Choose Mail (Microsoft Outlook) on the following page.
- Select Show Profiles to view the available profiles.
- Select Add on the following screen to make a new profile.

- Navigate to User Accounts > Mail (Microsoft Outlook).
- Select Show Profiles on the open window.
- Select the Always use this profile drop-down menu and choose your newly-created profile.
- Choose Apply followed by OK to save your changes.
3. Temporarily Turn Off Your Antivirus and Firewall
Your computer’s antivirus or firewall program might be causing interference with Outlook. This sometimes prevents you from sending and receiving new emails. In this case, temporarily turn off both those items and see if your issue is fixed.
How you turn off your antivirus and firewall depends on the programs you’re using. You’ll follow the following steps if you’re a Microsoft Defender Antivirus and Microsoft Defender Firewall user.
Turn Off the Antivirus
- Open the Start menu, find Windows Security, and launch the app.
- Select Virus & threat protection in the app.
- Choose Manage settings in the Virus & threat protection settings section.
- Turn off the Real-time protection toggle.
- Select Yes in the User Account Control prompt.
Turn Off the Firewall
- Open the Windows Security app.
- Select Firewall & network protection.
- Select the network that says (active).
- Turn off the Microsoft Defender Firewall toggle.
- Select Yes in the User Account Control prompt.
Launch Outlook and try to send or receive your email. Make sure to turn both the antivirus and the firewall back on when you’ve finished your tasks in Outlook. Keeping those items off makes your PC vulnerable to various threats.
4. Update the Offline Address Book
One reason you get the above error is that your Outlook cache is corrupted. Sometimes, this happens due to invalid address book entries. In this case, update Outlook’s offline address book to fix the issue.
- Launch Outlook and select the Send/Receive tab.
- Choose Send/Receive Groups in the Send & Receive section and select Download Address Book.
- Enable the Download changes since last Send/Receive option and choose OK.
- Quit and relaunch Outlook.
5. Repair Outlook
If you still get the above error, Outlook itself might be faulty. In this case, use Microsoft Office’s built-in repair tool to find and fix issues with your app. This tool helps you repair problems with other Office apps as well.
- Launch Control Panel on your PC.
- Select Uninstall a program.
- Choose your Microsoft Office installation on the list and select Change at the top.
- Choose Yes in the User Account Control prompt.
- Select Quick Repair and choose Repair in the open tool.
- If the problem persists, use the Online Repair option in the tool.
