Core Capabilities of Aryson OST to Office 365 Import Tool
The tool helps users to export OST files to Office365 without any issues
Migrate OST to Exchange Online
Microsoft Exchange Online is a cloud-based email service included with Microsoft 365. The tool migrates mailbox data saved in OST files to primary mailboxes, archive mailboxes, and public folders. During migration, the original folder hierarchy remains the same. This helps users assign the OST file to the appropriate destination mailboxes
Convert OST Files Without Installing Outlook
An OST file is only accessible via the same profile from which it was created. This OST to Office 365 import tool can access these files directly. Also, the tool doesn't require an Outlook server. It's convenient for orphaned files and system modifications. It's convenient for orphaned files and system modifications.
Move Straight Into Another Email Client
The user's source account must already be signed in on that device. After that, they can connect the destination account and then directly “migrate OST files to shared mailboxes" on Office 365, Gmail, Google Workspace, Outlook.com, GoDaddy Mail, and IMAP servers, which are among the supported services.
Batch Conversion for Large Files
The OST Converter allows users to import several OST files or one complete folder through the Select Files and Select Folders tabs. The OST Converter application does not impose any size limitations on large files, which saves administrators a lot of time in mailbox migration.
Authentication through OAuth and Client ID & Secret for Microsoft 365
You can sign in with either Modern Authentication or a Client ID and Secret that is created via an application within your Microsoft account. Administrative consent is needed only if the permission level extends beyond the scope of any single user's data.
Mapping Default Folders and Folder Hierarchy
Folders (Inbox, Sent Items, Drafts, etc.) can be mapped to the default folders at the destination. It has two hierarchy options. First, in the tree hierarchy, the hierarchy of the source folder and its subfolders is maintained. Second is the default hierarchy, in which the folder structure remains the same as it was before migration.
Mailbox Mapping for Microsoft 365
You can map each OST file to its target mailbox during OST to Microsoft 365 migration. For example, a user can map either to the destination user, or they can import multiple users from a CSV file. 1-to-1, 1-to-many, many-to-1, and many-to-many mapping are supported by the tool.
Advanced Preview Panel
To view a preview of any message, the user will need to double-click on the message. From, To, Subject, and Date fields will be visible at the top, with HTML, Headers, MIME, and Raw HTML being shown at the bottom. Users can also preview contacts, calendars, tasks, and notes.
Date Range Filter
Users have a choice to select a start and an end date to migrate emails created only within a selected time span. It reduces the conversion of unwanted data and allows you to choose a small amount of data from a dataset.
Export Without Attachments
Email attachments can be migrated with, without, or separately. Excluding attachments reduces the output size and shortens the conversion time when attachments are not required. But if users want to “migrate OST files to primary mailboxes," there might be a chance that attachments could be important.
Remove Duplicate Emails
It searches for duplicates based on To, From, Subject, Bcc, and Body fields and then filters duplicate emails. After that, they are delivered to the destination location. The Skip Existing Exports feature of this tool also saves you from re-exporting items exported earlier.
Custom Folder Name and File Naming
Rename the output folder during conversion and apply naming patterns such as date, subject, and sender. This keeps converted mailboxes organized and makes specific emails easier to find.
Track Your Migration
After migration, users can download the migration report from the monitoring panel. This report contains file size, destination path, file name, migration time, etc. The downloaded migration report can be shared with teams for future review. The monitoring panel is more useful during bulk migration, as the organization can track the state of migration.
Skip Previously Migrated Files
If any individual is doing repetitive migration to sync new emails into the destination account. In that scenario, enabling this option skips those emails that are already migrated in the previous migration process. This eliminates the chances of duplicate emails from appearing in the destination.
Simple Interface and Free Demo
The OST to Office 365 migration tool has well-labeled menus that allow even nontechnical users to use this tool easily. All the functions of the licensed edition are available in the free trial, with the limitation of 50 items per folder for export.
Detect Corrupted, Blank, or Invalid Files
The software identifies corrupted, blank, and invalid files among the selected OST files. Corrupted files should be repaired with an OST recovery tool before conversion.
