Import OST to Outlook 2016

Offline Outlook Data Files or OST are used to store offline data of IMAP accounts and Exchange or Office 365 accounts. OST files are copies of mail items saved on the mail server. Unlike PST files, OST files are not required to be backed up. But OST profiles are profile specific and it is not possible to access or read an OST file without the original profile. However, it is now possible to import or read OST files using professional third-party tools such as Kernel for OST to PST Converter. The tool not only imports OST to PST, but it is capable to convert OST to MBOX, PDF, DBX, EML/MSG, etc.

Following are some of the situations in which converting OST files to PST is helpful:

  • When the server is down, and the Outlook OST file is now orphaned, then it is required to convert OST to PST and later import data from that PST file.
  • Exchange database files are inaccessible due to corruption or server crash.
  • When backing up a few Exchange mailboxes.
  • In a scenario when you have decided to close an Exchange account and would like to access those emails later. Before removing the mail account from Exchange, one should export all the mail items to a PST file, which can be accessed then by importing these PST files in an Outlook desktop client.
