Stellar Converter for OST Review – An Advanced Software for OST to PST Conversion

Everyone is aware that OST and PST are data files that are associated with Outlook. However, sometimes, users need to convert OST files into PST format due to different reasons.

Below are some situations in which a user needs to convert the OST file into PST:

  • To access the emails when unable to connect to the Exchange or IMAP account.
  • Unable to view emails because the Outlook mailbox on the server is deleted.
  • Microsoft Exchange server is under maintenance and the user needs to access the data in the mailboxes.
  • An employee has left the company and there is a need to access the emails and attachments stored in the OST file.
