Integrations

Stella OST to PST Converter integrations

Stella OST to PST Converter works with Microsoft Outlook data files from Outlook 97 through Outlook 2021, on both 32-bit and 64-bit Windows systems. It reads offline OST files and writes PST files that can be imported back into Outlook, or exports mailbox items as EML, EMLX, MSG, MBOX, HTML, and TXT for use in other email clients such as Thunderbird or Apple Mail. For moving mail to the cloud, it migrates recovered data directly to Gmail and other IMAP accounts. It runs as a standalone Windows desktop application, so there is no API, and teams use its exported files within their existing email and archiving workflows.
