Why Choose DRS Softech Export Office 365 to PST Tool

Back Up Before Offboarding or a Tenant Change

When an employee leaves the organization or mailbox data needs to be saved for any reason, it is possible to use the Export PST Tool to export data from a Microsoft 365 mailbox to PST. Using this utility, the administrator can choose several backup sources, including Primary Mailbox, Online Archive, Shared Mailbox, and Public Folder.

Move Data Out of the Cloud Without Losing Structure

The tool provides folder-level selection so administrators can choose the required mailbox folders before starting the export. PST is used as the local destination, making it suitable for organizations that need mailbox data available outside the Microsoft 365 mailbox environment.

Scale From One Mailbox to an Entire Organization

Single User OAuth can be used for individual mailbox exports, while the Client ID and Secret method supports organizational backup workflows. Administrators can use a Microsoft Entra ID app registration along with CSV-based mailbox mapping to manage multiple mailbox exports more efficiently.

Advanced Features of DRS Softech Export Microsoft 365 to PST Tool

backup

Single User OAuth Authentication

Connect to Microsoft 365 via Single User OAuth authentication. Administrators can use Office 365's authentication flow to log in and allow the application by giving the necessary permissions, and then initiate the backup procedure.

secret

Client ID & Secret Authentication

For organizational and bulk backup scenarios, this authentication method uses a Microsoft Entra ID app registration with Client ID, Client Secret, Tenant ID, and Admin Email. It provides multiple mailboxes, with mailbox details available through a CSV for bulk migration.

migrate

Backup Source Selection & User Mapping

Choose which mailbox folder to back up for all users, including Primary Mailbox, Online Archive, Online Folder, and Shared Mailbox. Administrators can apply source settings to users and customize source selection for individual accounts through user mapping.

folder

Folder-Level Selection

View the mailbox folder hierarchy and, for backup, select and deselect individual folders. Before starting the Exchange Mailbox to PST export, show the selected folder total and approximate item counts.

filter

PST Export Filters

Apply filters to control the data, such as removing duplicates, freeing up space, date range, custom folder name, split output file size, and excluding empty folders.

select-img

Item Type & Output Controls

Select the data items to be included in the backup, such as emails, calendar, tasks, attachments, contacts, notes, etc. Split large PST files by size and select a specific output destination for the administrator.

action

Active Tasks Monitoring

Monitor backup activity through a live dashboard showing overall progress, elapsed time, item counts, failed and skipped items, along with progress across individual folders and data types such as mail, notes, contacts, tasks, and calendar items.

Detailed Backup Reports

Review completed backup sessions in the reports section containing details such as mailbox, source, destination, start time, authentication method, total items, migrated items, failed items, and final status.

Real-life Scenario to use Exchange Server to PST Backup Tool

Employee Offboarding

Scenario:If the employee leaves the company, and prior to deactivating his Microsoft 365 account, it is necessary to save mailbox data.

How the Tool Helps: The tool allows exporting the mailbox of a former employee via single-user OAuth; the administrator can extract the entire mailbox with the ability to exclude the necessary folders, and then save the extracted data in a local PST file.

Legal Hold or Compliance Archiving

Scenario: Locally store a copy of the specific mailbox as a requirement of legal or compliance.

How the Tool Helps: The date range filter exports the specific date range of data. In the report section, review the backup session details, including preserved, skipped, and failed items for future verification.

Reducing Reliance on an Active Cloud Mailbox

Scenario: Organizations require mailbox information to be locally accessible in Outlook without incurring the cost of maintaining each account active in the cloud.

How the Tool Helps: Microsoft 365 mailbox data is exported to the PST file format and saved in local storage or network storage. PST is an Outlook-compatible format; access the exported mailbox data through Outlook.

Bulk Export Across a Department

Scenario: During the department restructuring, export the bulk mailboxes at once rather than one at a time.

How the Tool Helps: The Client ID and Secret authentication method combined with a CSV list of mailbox addresses lets an administrator map and back up multiple accounts in a single run instead of authenticating each one individually.
