What is OST File Format?
OST (Offline Storage Table) file format is a file that stores a copy of mailbox items from an Exchange server, allowing users to access their mailbox data even when they are offline. OST files are synchronized with the Exchange server when a connection is established, ensuring that any changes made offline are updated on the server as well. OST files are used by Microsoft Outlook for email, contacts, calendars, tasks, and other mailbox items in an Exchange environment.
What is MHTML File Format?
The MHTML (MIME HTML) file format is a standard for archiving and saving web pages or email messages as a single file. It combines HTML content and resources such as images, stylesheets, and scripts into a self-contained document, making it easier to share and preserve the original layout and appearance of the content. MHTML files are often used for offline viewing, archiving, or sharing web pages or emails with all their components intact.
