To Import PST to Office365 Archive Mailbox manually, you can use the Network Upload or Drive Shipping methods provided by Microsoft. The Network Upload method involves uploading the PST files to Azure Storage and then mapping them to user mailboxes via the Import Service in Microsoft Purview. The Drive Shipping method requires copying PST files to an encrypted hard drive and sending them to Microsoft for upload. However, these manual methods are complex, time-consuming, and require technical expertise. Challenges include large PST file sizes, the risk of data corruption, mapping errors, and potential downtime.
