Offline Storage Table or OST is an offline Outlook data file that stores all the Exchange, Office 365 (Microsoft 365), Outlook.com, and IMAP mail items and allows users to work offline and synchronize changes with the Exchange server when the network connection is restored. It is also encrypted by default with the MAPIEntry GUID key. Hence, you cannot access or import the OST to any other Outlook account or profile.<\/p>\n<p><strong>Also Read: <a href=\"https:\/\/www.stellarinfo.co.in\/blog\/ost-file-corruption\/\" target=\"_blank\" rel=\"noopener\">Introduction to OST File, its Problems and Solutions<\/a><\/strong><\/p>\n<p><a href=\"https:\/\/www.stellarinfo.co.in\/software\/buy\/ost-pst\/buy-now.php?utm_source=Blog&amp;utm_medium=OST-PST&amp;utm_campaign=Blog-Mid-Banner\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-22994 size-full\" src=\"https:\/\/www.stellarinfo.co.in\/blog\/wp-content\/uploads\/2023\/09\/mid-banner-Stellar-Converter-for-OST.jpg\" alt=\"mid-banner-Stellar-Converter-for-OST\" width=\"850\" height=\"350\" srcset=\"https:\/\/www.stellarinfo.co.in\/blog\/wp-content\/uploads\/2023\/09\/mid-banner-Stellar-Converter-for-OST.jpg 850w, https:\/\/www.stellarinfo.co.in\/blog\/wp-content\/uploads\/2023\/09\/mid-banner-Stellar-Converter-for-OST-300x124.jpg 300w, https:\/\/www.stellarinfo.co.in\/blog\/wp-content\/uploads\/2023\/09\/mid-banner-Stellar-Converter-for-OST-150x62.jpg 150w, https:\/\/www.stellarinfo.co.in\/blog\/wp-content\/uploads\/2023\/09\/mid-banner-Stellar-Converter-for-OST-768x316.jpg 768w, https:\/\/www.stellarinfo.co.in\/blog\/wp-content\/uploads\/2023\/09\/mid-banner-Stellar-Converter-for-OST-610x250.jpg 610w\" sizes=\"auto, (max-width: 850px) 100vw, 850px\" \/><\/a><\/p>\n<p>On the other hand, a Personal Storage Table or PST file is a personal folder file that Outlook uses to store all your POP3 email, contacts, calendar, and other data.
