OST Recovery System Requirements and Supported Platforms
Review the processing workstation, Outlook/PST export, and direct-migration requirements before using the EdbMails OST recovery workflow.
Install EdbMails on a supported Windows workstation that can access the source OST and, when direct migration is required, the target environment.
- You can access the OST file in the network by sharing it and you need to provide read and write access to the OST file share.
- Any client workstation connection to target server.
Use a supported and fully patched Windows operating system for the current EdbMails release.
- Supports Both 32 and 64 bit machines.
- Windows 7
- Windows 8
- Windows 10
- Windows 11
- Windows Server 2003
- Windows Server 2008
- Windows Server 2008 R2
- Windows Server 2012
- Windows Server 2016
- Windows Server 2019
- Windows Server 2022
Note: Confirm the current EdbMails release notes and support documentation before deploying on legacy Windows versions.
We recommend that you use at least a quad-core CPU with a minimum of 4 GB of RAM.
Size of the installation file
- Installation of additional components (like .NET framework) 100 MB of available disk space.
- The application doesn't store the data, being migrated at any temp location on your local disk.
- Meta-data for Incremental check will be of the minimal size required.
- EdbMails requires an Internet connection ONLY to authenticate your login credentials and to verify the number of available and used mailboxes licenses. In addition, you may require the Internet connection to migrate your Office 365 mailbox data.
A supported Outlook installation with a configured profile is required for PST export. Verify the current supported Outlook versions before deployment.
Target server requirements:
Migration to any version of Exchange Server starting from Exchange 2007 supported
- Office 365
- Exchange 2007
- Exchange 2010
- Exchange 2013
- Exchange 2016
- Exchange 2019
- Windows Small Business Server (2008 and later)
- Hosted Exchange Server
Note: To export to Office 365 or to Exchange server no need to install MS outlook.
These permissions apply to direct Microsoft 365/Exchange migration workflows, not local OST scanning or PST export. Authentication and role requirements can vary by target and EdbMails release.
- Appropriate Office 365 account credentials should be provided for the connection.
- Should be mailbox-enabled (An Office 365 license should be assigned)
- Must have a UPN address configured
- The below roles should be assigned:
- ApplicationImpersonation
- View-Only Recipients
- View-Only Configuration
- User management administrator/Global administrator
- For the Public folder migration needs to assign public folder for the required user.

Separate Source Compatibility from Processing Environment
| Compatibility layer | What must be verified |
|---|---|
| Source OST | Outlook generation, ANSI/Unicode format, file condition and account type. |
| EdbMails workstation | Supported Windows edition, architecture, memory, disk space and required components. |
| Destination PST | Supported Outlook version, profile access and PST format/size requirements. |
| Direct migration destination | Microsoft 365 or Exchange permissions, authentication and service prerequisites. |
Preflight Compatibility Test
- Confirm the current EdbMails system requirements.
- Copy one representative OST to the processing workstation.
- Scan, preview and export the trial allowance.
- Open the test PST in the intended Outlook destination.
- Repeat with a damaged, older or larger source when the production set varies.
