Comprehensive Features of Aryson Import PST to Office 365 Tool
Directly Migrate PST to Microsoft 365
Aryson PST to Office 365 Migration Tool transfers Outlook PST data directly to Microsoft 365 without requiring an intermediate file format. Select Microsoft 365 as the destination, and select the authentication method—modern OAuth or impersonation. No credentials are stored on any external server.
Batch PST Migration
Process multiple PST files in a single migration session instead of handling each file separately. The batch processing option of this Outlook to Office 365 converter is suitable for administrators and organizations migrating data from multiple Outlook users. PST files can be added individually or through folder selection and drag-and-drop options.
Flexible Microsoft 365 Mailbox Mapping
Map individual or multiple PST files to their corresponding Microsoft 365 mailboxes using manual, bulk, or CSV-based mapping. You map multiple files to a particular admin account using manual selection or CSV import. Alternatively, you can map each file to a specific mailbox. The mapping interface allows administrators to review the configured source and destination accounts before starting the Outlook to Office 365 migration.
Advanced PST Preview
With this Import PST to Office 365 Tool, review PST mailbox contents before initiating the migration. The preview panel provides access to emails, attachments, contacts, calendars, tasks, notes, headers, MIME information, HTML content, plain text, and raw HTML. This allows users to verify source data before transferring it to Microsoft 365.
Selective Email Migration
Use the available search and filtering options to find out which mailbox data you really need to migrate. You can search for emails by subject, recipient (To), or sender (From); whilst the date-range filter lets you narrow down your migration to a very specific time frame indeed.
Duplicate Email Removal
The duplicate removal option identifies redundant emails during the migration process. The Aryson PST to Office 365 Migration Tool can compare supported email fields, including To, From, Subject, Bcc, and Body, to help prevent unnecessary duplicate data in the migration output.
Folder Structure and Default Folder Mapping
This is a comprehensive software that allows you to backup Office 365 mailbox data as well as restore Outlook data files. Besides PST, one can import an OST file to Office 365 as well. It possesses all other features similar to PST to O365 import.
Better Attachment Management
Control how email attachments are handled during migration. Users can retain attachments with their respective emails, save attachments separately, or exclude attachments when they are not required. This provides greater control over the amount of data transferred to the Microsoft 365 mailbox.
Handle Large PST Files via Splitting
The software provides PST splitting capabilities to migrate large Outlook archives. Divide large resultant PST files into smaller PST files according to the selected size. PST splitting can make large archives easier to store, manage, transfer, and process when working with extensive Outlook mailbox data. Along with that, the risk of PST file corruption decreases, which eventually improves Outlook performance.
Custom Naming Convention
Outlook to Office 365 Converter lets you apply a defined naming pattern to exported mailbox data. The available fields are Date, Subject, and Sender. Custom naming helps maintain consistent identification of files and organized storage when processing multiple PST archives.
Corrupted PST Detection
The software detects and reports corrupted, locked, invalid, or blank PST files before processing. This allows users to identify problematic source files before proceeding with the Outlook to Office 365 migration. Microsoft also notes that corrupted PST items may be skipped during Microsoft 365 PST import, making source-file validation an important migration consideration.
Migration Progress and Export Reports
Track the migration process through the built-in progress indicator and review the generated export report after completion. The reporting functionality provides a record of the processing status and results for migration tasks.
Microsoft 365 Migration Monitoring
Monitor the progress of PST migration and review processing results after completion. Microsoft 365 imports can be affected by service-side processing rates and mailbox conditions, so migration status and reporting are important when processing large or multiple PST archives. Microsoft states that its PST Import service has a typical ingestion rate of approximately 24 GB per day, although this rate is not guaranteed.
Windows and Outlook Compatibility
The Import PST to Office 365 Tool supports multiple Windows and Outlook environments, including Windows 11, 10, 8.1, 8, 7, Vista, XP and supported Outlook versions, including 2024, 2021, 2019, 2016, 2013, 2010, and earlier versions as documented in the product material.
