MSOutlookHelp Office 365 Backup Software enables complete, secure, and reliable full mailbox export from Microsoft 365 with zero data loss. Follow the steps below to back up or migrate Office 365 mailboxes to other file formats & email clients effortlessly.
Explore the enterprise-grade features to deliver secure authentication and an effortless backup experience.
The Office 365 Backup Tool uses Microsoft-approved Modern Authentication with OAuth 2.0 via Microsoft Graph and Exchange Web Services (EWS). This ensures a highly secure, token-based login without storing usernames or passwords, fully supporting MFA and enterprise security policies.
Users can connect Office 365 accounts using browser-based Modern Authentication or Azure AD App-based authentication (Client ID, Tenant ID, and Client Secret). This makes the Office 365 Mailbox Backup Tool suitable for both individual users and administrators managing multiple mailboxes or tenants.
The Microsoft 365 Backup Tool supports all Office 365 mailbox types, including Primary Mailboxes, Online Archive Mailboxes, Shared Mailboxes, and Public Folders. This guarantees complete organisational data coverage without requiring additional tools.
Users can back up Office 365 mailbox data into widely used formats such as PST, MBOX, EML, MSG, PDF, and CSV, allowing easy restoration, migration, and offline access.
The MSOutlookHelp Office 365 Email Backup and Restore Tool allows direct migration of Office 365 data to Office 365 tenants, Google Workspace (G Suite), and IMAP-based email services, ensuring effortless cross-platform data transfer. All your data and folder hierarchy will remain intact after migration.
Administrators can back up multiple Office 365 users and mailboxes simultaneously. This batch processing capability saves time and makes the Office 365 Backup software ideal for enterprises and IT professionals handling large environments. This also saves the time of the user and increases their productivity.
Users can choose specific mailbox folders such as Inbox, Sent Items, Drafts, Archives, or custom folders, ensuring only required data is backed up and stored. You can also map your O365 folders to GSuite’s Folders.
The Date Filter of O365 Backup Tool allows backups from a specific time range, while the Remove Duplicate feature eliminates redundant emails based on sender, recipient, subject, or body, improving performance and storage efficiency.
A built-in preview panel displays mailbox folders and items before backup. The tool preserves original folder hierarchy, metadata, attachments, and email formatting, ensuring 100% data integrity.
When exporting Office 365 data to PST, the Office 365 Email Backup and Restore Tool can split oversized PST files into smaller segments. You can provide the size of PST using the dropdown of value and the MB/GB. In this way, you can increase the processing speed of smaller sub PSTs.
Users can define custom names for backup folders, making it easier to manage and identify backed-up Office 365 data. Just navigate to your file explorer and search with the same name of folder and you will find it in no time.
The Office 365 Email Backup Tool generates detailed backup and migration reports without storing mailbox content, supporting compliance, audits, and internal tracking. Users can easily download it at the end of the migration.
