Learn How to open OST files in Microsoft Outlook. This tutorial helps you how to open a corrupted or damaged OST file in another system. Then you are able to access your email messages of OST. How to Import an OST File in Microsoft Outlook by Bennett Gavrish The Microsoft Outlook application automatically creates an OST file, or offline folder file, when you initially configure the program to connect to an email account.
Note: If your organization has policies in place that archive email messages automatically, your older email messages, calendar events, and tasks might be stored in an archive Outlook Data File (.pst). Even if your account uses an offline Outlook Data File (.ost) for all of its day-to-day information, you may still have an archive.pst file that contains older information.
Open an Outlook Data File (.pst)
Select File > Open & Export > Open Outlook Data File.
Note: Depending on how Outlook is set up, it's likely the folder where the .pst file is stored will open automatically. If it doesn't, browse to the file's location. If you're not sure where your Outlook data file is located, see Locating the Outlook data files.
Select the Outlook Data File (.pst), and then select Open.
Once you open the Outlook Data File (.pst), the file will appear in your folder pane. Usually you'll find it at the bottom of the list of folders. The following image is an example. The name of your Outlook Data File (.pst) will likely not be outlook data file. Usually, the name is based on the account the file is associated with. For example, an Outlook Data File for the account Cheryl.Parsons64@yahoo.com will likely be named Cheryl Parsons or Cheryl.Parsons64@yahoo.com.

You can remove an Outlook data file from the Folder pane by closing the file. This does not, however, remove the file from your computer.
In the Folder pane, right-click the name of the Outlook Data File, and then choose Close 'Outlook Data File'.

The .pst data file does not support read-only media such as CDs and DVDs.
If you use a Microsoft Exchange account, typically your e-mail messages, calendar, contacts, and other items are delivered to and stored in your mailbox on the server. When you install Outlook on a new computer and configure an Exchange account, all your items on the server will be available to you again. The remaining information in this article does not apply to you, unless you have archived local data files or specified that your Exchange email messages be delivered to a local data file.
If you use a POP3 email account, which is one of the more common types of personal e-mail account, your email messages are downloaded from your POP3 e-mail server at your Internet service provider (ISP) to your computer and delivered to and stored locally in a Personal Folders file (.pst) named Outlook.pst (the default data file name). Outlook.pst is stored in the drive:Documents and SettingsuserLocal SettingsApplication DataMicrosoftOutlook folder.

Before you move your .pst file, you might want to change its display name from Personal Folders to something more meaningful to you. Changing the name helps you to distinguish between different Outlook data files when you work with more than one .pst file.

Data file security
Currently there is no way to password-protect Outlook on startup or to lock Outlook if you need to quickly walk away from your computer, other than by using your Microsoft Windows logon password or by using third-party software written specifically to password-protect Outlook. However, you can set a password on your Personal Folders file (.pst). If you use an Internet e-mail account in Outlook, such as a POP3 or HTTP account, your e-mail messages are delivered to a .pst data file on your computer's hard disk. You can use a password on your .pst file to help prevent accidental intrusion by other people with whom you share your computer.
On the Go menu, click Folder List.
Do one of the following:
If you have a POP3 e-mail account, right-click Personal Folders, and then click Properties For 'Personal Folders' on the shortcut menu.
Note: If you provided a custom display name for your data file, substitute that name for Personal Folders.
If you have an IMAP or HTTP e-mail account, such as Microsoft Windows Live Mail, right-click the name of the account, and then click Properties For account name on the shortcut menu.
On the General tab, click Advanced.
Click Change Password.
In the Change Password dialog box, type your new password—up to 15 characters—and verify it by retyping it .
Notes:
Use strong passwords that combine uppercase and lowercase letters, numbers, and symbols. Weak passwords don't mix these elements. Example of a strong password: Y6dh!et5, and an example of a weak password: House27. Passwords should be 8 or more characters in length. A pass phrase that uses 14 or more characters is better. For more information, see Create stronger passwords and protect them.
It is critical that you remember your password. If you forget your password, Microsoft can't retrieve it. Store the passwords that you write down in a secure place away from the information that they help protect.
Make sure that the Save this password in your password list check box is cleared. This prevents the password from being cached, so you will need to type the password each time you run Outlook. Don't forget the password.
Pirates of the caribbean 6 latest news. Pirates of the Caribbean 6 Is Happening, Will Johnny Depp Return? Disney is reportedly in the early stages of working on Pirates of the Caribbean 6. This comes after the release of last year's latest entry in the franchise, Pirates of the Caribbean: Dead Men Tell No Tales.

Important: Neither Microsoft, your Internet service provider (ISP), nor your mail administrator has access to your password, nor can they assist you to recover the contents of the .pst file if you forget the password.
Click OK three times.
When you click the email account folder, you will be prompted for your password. After you gain access, you won't have to enter the password again for that session. If you exit and then restart Outlook, you will be prompted for the password when you click the e-mail account folder.
Important: The .pst password feature is not intended to provide security against hackers. It is just a way to prevent inadvertent intrusion by other people whom you trust and share your computer with, such as at home with your family. A more secure way of protecting your data on a computer that you share with other people is to create a password-protected Windows user account for each individual who uses the computer.
Customize the display name of the data file
The default display name of the Personal Folders file (.pst) is Personal Folders. This can be confusing if you work with multiple .pst files, all of which have the same name. A best practice is to customize the display name.
In the Navigation pane, right-click Personal Folders, and then click Properties for 'Personal Folders'.
Click Advanced.
In the Name box, type a name that is meaningful to you, such as Greta's Outlook Data.
Click OK twice.
How To Open Ost File In Outlook 2010
In the Navigation pane, you see a top folder with the name that you entered. Now you can quickly distinguish your data file from any others.
Tip: Customizing the file names is also useful if you keep multiple .pst file archives. For example, if you create a monthly .pst file to store all of your sent items for that month, you can rename the display name from Personal Folders to something more friendly, such as Sent Mail Archive – December 2007.
Remove a .pst file from the Navigation pane
Even if you have a tendency to hoard e-mail, you might want to clear some of the clutter in the Navigation pane. You might not always need instant access to an archive .pst file. You can remove an Outlook data file from the Navigation pane without deleting the file from your computer.
Right-click the Personal Folders file that you want to remove from the Navigation pane, and then click Close Personal Folders.
If the Close Personal Folders option is not available, you are probably trying to remove the .pst file that Outlook uses for saving your new messages. If you remove that data file, new messages will have nowhere to go.
Tip: Afraid of deleting a file and losing your data? Closing a .pst file doesn't delete the file or any items that it contains. The file just no longer appears in the Navigation pane. You can always add any .pst file back to the display by doing the following:
On the File menu, point to Open, and then click Outlook Data File.
Click the .pst file that you want to open, and then click OK.
