Unlike many traditional backup utilities, BreviSoft combines backup, restore, and migration features into one application. Users can export Office 365 mailboxes into multiple file formats, restore PST and OST files back to Microsoft 365, and migrate Office 365 accounts directly to Gmail, Exchange Server, Microsoft 365 tenants, or any IMAP-enabled email account. This all-in-one functionality reduces the need for multiple software solutions.

During every Office 365 backup operation, the software preserves all email properties and mailbox information without modification.

This ensures restored or exported emails remain identical to their original Microsoft 365 mailbox structure.
BreviSoft securely backs up Office 365 emails together with all associated attachments, including PDF files, Word documents, Excel spreadsheets, PowerPoint presentations, images, ZIP archives, videos, and other file types. Every attachment is preserved in its original format, filename, and quality, ensuring complete mailbox data remains available for future access, migration, or compliance requirements.

Shared mailbox data used by customer support, sales, HR, finance, and collaborative teams can be safely archived without losing email integrity. This feature helps organizations maintain business continuity and protect important shared communications.
In addition to primary mailboxes, BreviSoft also backs up Microsoft 365 Online Archive mailboxes with complete accuracy. Archived emails remain properly organized along with their original folder structure, metadata, and attachments. This feature helps organizations meet legal, compliance, auditing, and long-term email retention requirements while ensuring historical business communications remain easily accessible.
BreviSoft enables administrators to create complete Microsoft 365 tenant backups by exporting multiple user mailboxes in a single operation. This centralized backup capability simplifies enterprise data protection, disaster recovery planning, and compliance management. Organizations can efficiently safeguard their entire Microsoft 365 environment while reducing administrative effort and minimizing backup management complexity.
Every backup performed by BreviSoft operates in a completely secure read-only mode, ensuring that no changes are made to the original Microsoft 365 mailbox. The software never edits, deletes, overwrites, or modifies existing emails or folders during backup or migration. This guarantees complete data integrity, maximum security, and reliable protection of business-critical mailbox information.
The software is powered by an advanced, high-performance processing engine designed to efficiently handle large Microsoft 365 mailboxes containing thousands of emails, folders, and attachments. Optimized backup algorithms ensure faster data processing while maintaining complete accuracy and mailbox integrity. This significantly reduces backup duration and improves productivity for both individual users and enterprise environments.
