Top Use Cases
When a user's mailbox gets deleted from the Exchange Server without a backup, the mailbox data is retrievable using its OST file. However, once the user's account gets deleted from the server's Active Directory, the OST file becomes inaccessible. To regain access to mailbox data, OST files need to be converted to PST, as PST files can be accessed independently. Stellar Converter for OST converts the inaccessible OST file to PST, which can then be imported back to the Exchange server and accessed through Outlook.
Learn MoreWhile using the Hosted Microsoft Exchange service, if the server gets compromised and users lose access to their emails, the Offline Outlook Data File (.ost) serves as a vital backup of all mailbox data. Stellar Converter for OST can migrate these OST files directly to Microsoft 365 while preserving the data and maintaining the original organizational structure. This ensures that all emails, attachments, contacts, and other crucial information remain accessible and secure, even in the event of a server failure or security breach.
Learn MoreThere are instances when the OST file becomes inaccessible. This will happen when the OST file fails to synchronize with the Exchange server due to connectivity or server errors. OST becomes inaccessible even when the user account gets deleted from the Exchange Server as OST will no longer have access to the server for synchronization. In such cases, user has to rebuild the OST files, but this happens when the mailbox is still active on the server. Stellar Converter for OST extracts the data from OST files even when the mailbox is no longer active on the server.
