want to use my earlier mail box if possible

I am using Office LTSC 2021. Recently there was some issue and my profile was corrupted, on trying several options, the option that I had to do was uninstall my Office, restart and install Office again. I made the profile again,
There are many mails in the earlier profile which are not accessible, that big mail box is in C:\Users\Smes\AppData\Local\Microsoft\Outlook the file size is about 6 GB. is there a way to import this mail box into outlook? these mails are offline mails and these mals are no longer online a had to delete those mails from online server to make sure there is space in the online mail box.
Any help?
