The Difference

If a user connects Outlook 365 account, or IMAP, with Microsoft Outlook 2010 and later versions, an OST file will automatically be created in a default location. In the same way, if a POP email account is added to the Outlook client, it will create a PST file. The main difference between OST and PST is-   

  • OST file is encrypted with keys like MAPEntryID GUID that require verification from the MAPI profile (linked). Therefore, it is impossible to import an OST file or access it into any other Outlook profile. However, you can easily import or access PST files by any outlook profile contrary to the OST file.
  • In addition, the location of these types of files (OST & PST) is different based on the windows the user is working on.
  • The maximum size allowed in OST and PST files can be around 4PB. But, by default Ost and PST size limits are Twenty GB in Outlook 2007 and 50 GB in 2010 (and earlier) Outlook version. You can always customize these size limits at your convenience but remember, the larger the file size, the worst your Outlook will perform.

 There are chances that it will crash, get corrupt, or become unstable. You may change this default size limit as per your or your organization’s requirements. However, it is highly recommended to keep the file size of OST or PST in recommended or default limits.
