DataNumen Exchange Recovery

What DataNumen Exchange Recovery is

DataNumen Exchange Recovery is Windows software that converts orphaned or corrupt Outlook OST files into PST files for use in Outlook. It supports Exchange 5.0 and later, Exchange ActiveSync, and MS Outlook 97 and later, including Outlook for Office 365 and Microsoft 365. Input can include offline OST files from IMAP accounts such as Outlook.com, Gmail.com, and Hotmail.com, as well as Microsoft 365 and Exchange accounts. The software can recover deleted objects and convert recovered items to PST, including oversized 2GB OST files. Batch recovery is supported, and users can preview results before export. Converted PST files can be accessed with Microsoft Outlook and other compatible email clients. The maker offers a free download, but does not state a trial duration, and there is no free plan. A one-user license costs $199.95, paid once, with discounted per-license prices for volume purchases. The maker says the full version is delivered immediately after an order and accepts payment through FastSpring, PayPro Global, and BMT Micro. It advertises a refund if another tool recovers more. Support materials include a knowledgebase, tutorials, online help, and a question form. DataNumen says it was founded in 2001 and lists offices in the United States, United Kingdom, and Hong Kong.
