Why am I repeatedly getting the error 'Exchange OST is in use and cannot be accessed'?

If you are getting the error "Exchange OST is in use and can't be accessed" even after closing all possible applications that may use the file, then probably it must be occurring because one or more of the closed applications is running in the background due to improper closure. Kindly follow the given steps to close them:
- Right click on the Taskbar and select 'Start Task Manager' or simultaneously press CTRL+ALT+DEL keys and select 'Start Task Manager'.
- Go to the Processes tab.
- Click on outlook.exe and click on End Process.
