Outlook Mailbox not showing all Mails in Inbox

Hi community,

I have my mail configured in Outlook and it's about 17GB. Unable to view 3 years of mails in Outlook inbox.
Tried many things like send/receive all folders, scan pst file, checked rules, view filter, select all mails , remove and add the account via control panel mail accounts etc. to fix this problem.

Please help me to solve this problem.
