An OST file is an offline folder
file in Microsoft Exchange Server. The offline folder enables users to work
offline whenever needed and synchronize the changes next time it connects to
the exchange server. This ability of work offline has many advantages like it
is very useful when the connectivity is limited or unreliable.
PST file is personal storage file.
It is simply stored on the client or a server other than exchange server. It
holds all the data when exchange server is not being accessed and used for
local email data storage. In exchange server, the messages, calendar, and other
data items are stored to the server. Outlook stores these items as
personal-storage-table (.pst format) or offline-storage-table (.ost format) on
the local computer. PST files store the archived data and OST file to maintain
offline availability.
Thousands of people depend on
Microsoft Outlook to check and maintain their email messages, calendar and
contact information and many more. If some error occurs while opening the
Outlook OST file then we need it to convert it into PST file format. Outlook
stores all the files in a single folder known as PST folder. The file stays on
the local hard drive used to store every email received, every calendar item,
every task scheduled or every note etc.
OST files are replicas of the user
mailbox on the exchange server. If the user mailbox is deleted from the server
or it gets corrupted then what would someone do with the orphaned OST files
saved in the computer? There lies the value of the tool which converts the OST
to PST files. To convert OST to PST you can download the program from the secured websites.
