Outlook Migration

Outlook for desktop (MS 365 Apps for business, version 2210

Recently GoDaddy migrated there inhouse email to Office 365.

Per tech support (migration) they said I should create a new Mail profile and recreate my 3 email accounts.  This worked fine as all email was migrated.

However - I do not have my calendar contents.  It was 1 calendar I used for everything.

How do I find it?  Should I load the previous profile and export?  Is there a .pst or .ost I can import from the outlook data folder?

Thanks!
