You can migrate your emails from PST file to Office 365 either manually using Outlook, with the help of Microsoft Network Upload function or using PowerShell. However, after a recent migration I noticed that both approaches have many issues especially when dealing with huge PST files. The Outlook technique was slow for big data and the Network Upload process involved several technical steps like generating SAS URL, using AzCopy and setting up CSV mapping files. In some circumstances, the import procedure even stopped or failed during validation.<\/span><\/p>\n

I tried numerous ways to import PST to Office 365 mailboxes to make the transfer succeed. In addition to manual approaches, I also used a professional PST to Office 365 migration tool which made the entire process more easier and minimized the risks of errors. In this article, I will discuss all the ways that I tested to move Outlook PST emails to Microsoft 365 mailboxes. Go through each one of them and choose the best solution that fits your needs and requirements.<\/span><\/p>\n
