One of the most common causes of this issue is file corruption. Outlook provides a built-in tool called Scanpst.exe (Inbox Repair Tool) that can repair damaged PST or OST files.

1. Make sure Outlook is completely closed before starting the repair process. 
2. Scanpst.exe is usually installed with Microsoft Office or Outlook, and its location depends on the version of Outlook you are using. 

For Outlook 2019 / Microsoft 365: C:\Program Files (x86)\Microsoft Office\root\OfficeXX\For Older Versions of Outlook (e.g., Outlook 2016, 2013, etc.): C:\Program Files (x86)\Microsoft Office\OfficeXX\ Replace XX with your Outlook version number.

3. Once you’ve located the Scanpst.exe file, double-click to run it. Click Yes to allow the program to run.
4. The Inbox Repair Tool will open. You’ll see a field labeled “Enter the name of the file to scan” or “Browse” button.
5. You’ll need to know the location of these files, depending on your setup:

PST File (Personal Storage Table): C:\Users\<username>\Documents\Outlook Files\OST File (Offline Storage Table): C:\Users\<username>\AppData\Local\Microsoft\Outlook\

6. After selecting your file, click Start to begin the scanning process.
7. After the scan completes, the tool will display a message telling you if any errors were found in the file.
   1. Errors found: You will be prompted to Repair the file.
   2. No errors were found: Indicating that no issues were detected.
8. If errors are found, click the Repair button to begin the repair process.
9. Once the repair process is complete. Open Outlook again.

2. Opt for the “Show Profiles” option.
3. Select the “Remove” option and confirm it.
4. Click Add to create a new profile.

6. After the new profile is created, select Prompt for a profile to be used or set the new profile as the default.

3. Turn off your firewall or antivirus software

Temporarily disable your firewall or antivirus software to check if it’s blocking the connection to Outlook. If this works, you must probably add Outlook to the exceptions list.

4. Repair Outlook Profile

To repair your Outlook profile, try the subsequent measures:

1. Press Windows + R to open the Run dialog, type the control panel, and hit Enter.
2. After that, in the Control Panel, select Mail (Microsoft Outlook).

1. Open File Explorer or press the window+E Key.
2. Go to the folder where your Outlook data file (PST or OST) is stored. By default, these files are located in:

6. If Full Control is not selected, check the Allow box next to Full Control.
7. After selecting Full Control, click Apply, then OK to close the Permissions window.

6. Repair Office Installation

If Outlook is unable to access the data file due to an issue with the Office installation itself, repairing Office might help resolve the problem.

3. Right-click and select Change, then choose Quick Repair or Online Repair.

1. Open Outlook and navigate to File > Office Account.
2. Click Update Options > Update Now.

1. Make sure Outlook is completely closed.
2. Open File Explorer and navigate to the current location of your PST or OST file.

PST File (Personal Storage Table): C:\Users\<username>\Documents\Outlook Files\OST File (Offline Storage Table): C:\Users\<username>\AppData\Local\Microsoft\Outlook\ Replace <username> with your actual Windows username.
