Take a Closer Look at Outlook FilesSpeaking of Outlook data files, we have to mention *.ost and *.pst, which are the two most significant files of Outlook.
Specifically, as a common kind of computer file formats, OST file has a particular sequence of SID to identify Outlook and Exchange mail account so as to associate the *.ost file with specific users. After you configured an Exchange email account to Outlook and selected the Exchange in cache mode, Outlook will synchronize the emails to the local *.ost file.
Note: the original *.ost file can only be opened in the original Outlook configuration file & exchange mail account configuration. So when you move OST file to another computer or try to open it in another Outlook configuration file, you'll end in failure.
As we said, the other significant file of Outlook is PST, which stands for Personal Storage Table.
"A *.pst is an open proprietary file format used to store copies of messages, calendar events, and other items within Microsoft software such as Microsoft Exchange Client, Windows Messaging, and Microsoft Outlook. The open format is controlled by Microsoft who provides free specifications and free irrevocable technology licensing."

OST File vs. PST File
A computer can save one or more PST files, while only one OST file can be stored on the same computer.
To be specific, PST file includes emails and other Outlook items; it is used by the most commonly used email account type (POP3 account). Outlook will download the emails of POP3 account from the mail server, and then save it to the computer local drive. So, the size of PST file is not limited by that of mailbox on the mail server; and we can release the storage space of mailbox on the mail server by moving items to the local Outlook data file (.pst).
In contrast, OST file is used by most other account types (such as Microsoft Exchange Server, Outlook.com, Google Gmail and IMAP) except POP3. When you use these kinds of accounts, your emails, calendar, and other items will be sent to and stored on the server. Meanwhile, Outlook will download the synchronized copy of the emails and save it to OST file – the offline Outlook data file – on computer, when network is connected.
If you accidentally deleted your emails and now need to get them back, you should gain methods from An Amazing Tool For Recovering Deleted Emails Efficiently, which tells more on how to recover deleted emails exactly.
Note: you can choose to convert OST to PST according to needs.
Noticing the increasing needs, software manufacturers began to make every effort to produce OST to PST converter. That's why you can easily find OST to PST tools, both free and paid, on the internet.
Location of OST Files
After reading above content, you may easily find the fact that OST files help us use Outlook when network connection is unavailable. See, *.ost file is so important.
We found some users choose to change the location of OST file on local computer mainly due to the following reasons.
a). They suddenly realize the importance of OST file.
b). They'd like to manage OST file more conveniently.
c). They want to release more free space in C drive, in order to improve computer performance.
Well, OST files become very easy to get lost during the transferring of files from one location to another, users' improper management and unintentional deletion. Beside, both OST file and PST file may corrupt all of a sudden. In view of this, we decide to mainly focus OST recovery in the next part (PST recovery can also be completed by using the following methods in most cases).
SummaryNeedless to say, Microsoft Office Outlook is a world famous email management tool. Since it is released by Microsoft, many people believe in it at the very beginning; they totally have no doubt about its security. Besides, with this tool, they can manage more than one mailbox conveniently.
Yet, problems can't be avoided. We tend to delete useful files when using computer; the virus/ransomeware attack, sudden power failure, drive can't be opened error and other unknown reasons can all lead to fatal data loss.
So, what we need to do when accidents really happen are: don't be panic, stop using the computer and seize time to choose proper tool to recover deleted Outlook files. This can greatly enhance the possibility of a successful recovery job.
