Why Organizations Rely on Aryson Exchange Server Backup Tool

The Challenge

Important business mailbox data is always at risk due to accidental deletion, hardware failures, ransomware, and mailbox corruption.
Manual backup techniques are complex and slow, particularly when safeguarding numerous mailboxes throughout a company.
You may be limited in your native recovery options and may not meet long-term backup, compliance, or disaster recovery needs.
Organizations require a secure, centralized backup solution that protects mailbox structure, folder hierarchy, and critical mailbox data.

With a safe, centralized platform to protect mailbox data, the tool addresses Exchange mailbox backup problems. Administrators can use advanced backup filters, selectively backup various mailbox types, authenticate using Single OAuth or Client ID & Secret, and support Exchange Public folder to PST migration while maintaining the original folder hierarchy and metadata.

The organizations that are restructuring their departments, subsidiaries, or business units need Tenant to Tenant Migration.

The result is an efficient backup solution that reduces administrative effort, improves backup performance through multi-threaded processing, and gives organizations greater control over Exchange Server and Microsoft 365 mailbox protection through secure local processing. You can also perform Exchange Online to Exchange Online (Microsoft 365) Mailbox Migration for mergers and acquisitions or tenant consolidation.

Enterprise-Level FAQs - Aryson Exchange Server Backup Tool

Does the software support Microsoft 365 to Microsoft 365 backup in addition to PST export?

Yes. The software allows administrators to choose the backup destination based on their requirements. Mailboxes can be exported to Outlook-compatible PST files for local storage or backed up directly to another Microsoft 365 environment while maintaining mailbox structure, metadata, attachments, and folder hierarchy.

What authentication methods are supported for Microsoft 365 backup?

The software supports two secure Microsoft authentication methods:

OAuth 2.0 (Modern Authentication) for individual mailbox authentication.
Client ID & Secret (Microsoft Entra ID Application) for enterprise deployments.

Client ID & Secret authentication also enables Shared Mailbox backup and centralized administration without requiring individual user authentication.

Can I selectively back up only specific mailbox folders instead of the entire mailbox?

Yes. After authentication, the software displays the complete mailbox folder hierarchy. You can browse, expand, collapse, search, select, or deselect individual folders before starting the backup. This allows administrators to back up only the required mailbox folders while preserving the original folder hierarchy.

Can Aryson Exchange Server Backup Tool back up multiple Microsoft 365 mailboxes in a single operation?

Yes. The software supports bulk mailbox backup using CSV-based user import and user mapping. This is ideal for large organizations with thousands of users that can back up multiple Microsoft 365 mailboxes in one operation. For further performance improvements, the multi-threaded backup engine can back up many folders concurrently.

Which mailbox types can be backed up using the software?

The software supports backup of various types of Exchange and MS 365 mailboxes, such as primary mailboxes, online archives, public folders (supported with both Modern Auth and Client ID & Secret authentication), and shared mailboxes (supported only with Client ID & Secret authentication). Each mailbox type can be selected individually in the backup configuration process.

What advanced backup filters are available to optimize mailbox backups?

The software provides several advanced filters to reduce backup time and storage consumption, including:

Date Filter
Duplicate Removal (based on To, From, Subject, and Body)
Skip Previously Backed-Up Items
Custom Folder Name
Exclude Empty Folders
Split PST by Size
Custom Output Location
Mailbox Item Selection (Emails, Contacts, Calendar Events, Tasks, Notes, and Attachments)

These filters help administrators perform precise and efficient mailbox backups.

How does the multi-threaded backup engine improve performance?

Up to three mailbox folders can be processed concurrently by the software's multi-threaded backup engine. When backing up large Microsoft 365 environments or Exchange Server mailboxes, parallel processing greatly shortens backup times when compared to sequential mailbox exports.

Does the software preserve mailbox integrity during backup?

Yes. This backup solution saves your whole mailbox with folder structure, formats of emails, metadata, attachments, events, contacts, tasks, and notes. The resulting PST files will fully work with Microsoft Outlook.

Are authentication credentials stored securely during the backup process?

Yes. The software runs entirely on the local machine and stores authentication credentials locally. No mailbox data or authentication information is processed through third-party cloud servers, providing greater security and control over enterprise backup operations.

Is there a trial version available, and what limitations does it have?

Yes. A free trial version is available for evaluation. The trial includes all the major features, including secure authentication, mailbox selection, advanced backup filters, PST export, and Microsoft 365 backup workflows. But the trial version is limited to backing up 500 email items per folder and 100 Contacts, Calendar Events, Tasks, and Notes per folder. The licensed version removes these limitations & allows unlimited mailbox backups.
