Outlook works with .pst files where all the information of the received messages and its folder configuration is hosted, we can try to repair this file to rule out that the cause of the error is the .pst file.
Step 1

This file is found in the following routes:
  • 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
Step 2

In the opened window we will open the file SCANPST.EXE: image
Step 3

In the pop-up window we will go to the path where the .pst file is:

Step 4

We click on "Start" to run the analysis and repair of the Outlook .pst file:

Step 5

After this analysis we will see a summary with the errors detected:

Step 6

We click on "Repair" to proceed with the general repair of the file. After this, when accessing Outlook, it is possible to view a new folder called “Recovered Personal Folders” in which we will see the default Outlook folders or a Lost and found folder with the data that has been rescued.
