To Import PST files to Online Archive in Office 365 manually, you can use the Network Upload method provided by Microsoft. This involves uploading the PST file to Azure Storage and then using the Import Service in the Microsoft 365 Compliance Center. The steps include obtaining the SAS URL, and uploading the PST file. After the upload, an import job needs to be created to map the PST data to the appropriate user mailbox. However, this process is complex, time-consuming, and requires technical expertise. Challenges include file size limitations, potential data corruption, and difficulties in mapping multiple mailboxes. Additionally, incorrect configurations may lead to data loss or import failure.
To simplify the process, the Cigati PST to Office 365 Migration Tool offers a hassle-free solution. This tool allows users to directly import PST files to the Online Archive without requiring manual uploads or complex settings. It ensures data integrity, supports bulk migration, and preserves folder hierarchy. Additionally, it comes with advanced filters to migrate only the required data, making it an efficient and secure alternative to the manual method.
