Office 365 PST Import Completed 100 % With Errors – Resolved

PROBLEM: “Imported PST file. Live status says Office 365 PST import completed with errors but when seeing details showing imported 100%“

I am using Azure AzCopy Tool to import a pst file to Office 365 account and then uploaded it. When I am checking current status showing completed with errors and when checking details no errors is there. I am using Office 365 Business Premium Plan. I am working on it to get the PST files into Office 365, but it seems like uploading is not working.

The second problem I am facing is that upload destination has a long URL and I got a key. Yet I don’t have Azure account, how to delete the uploaded file from that location, it is not accessible using URL?
