Recover emails from corrupt OST file for MS Office Outlook in Windows 10?

[ravensmith2018]

I am using MS Outlook application for windows on my Windows 10 laptop and suddenly I am unable to use outlook for emails, due to some error or damage in OST file. Now how could I get back my old emails and use Outlook again with the same email account?

Everything is in the cloud so it is really not an issue. Just re-connect to Outlook.
