Advanced Guide to Convert NST to PST Without Data Loss

Across enterprise migrations, many admins found NST files remain in their legacy, decommissioned accounts. This Group Storage Table File is a local cache file, like OST, as created by Outlook after connection with Office 365 or other connectors. For example: IBM Notes. It is also a locked container with emails and calendar data stored offline that cannot be opened or reused once the profile disappears. Hence, it is necessary to convert NST files to PST.

• Offline accessibility to group conversations
• In case of recovery from profile or device failure
• Access without the need for an Exchange profile
• Handling legacy and archival accounts and mailboxes
