Utilities to recover your mails from the OST file, in case of Exchange Server crash

OST or .ost files are related to your MS Outlook application. OST stands for Offline Storage Table file and helps in accessing your mailboxes, even if you are not connected to the Exchange Server. Also in cases of any problem with the Exchange Server database, these OST files are extremely helpful, as you can convert OST to PST and again access your mail account through your Outlook.

MS Outlook is an email client and stores all your mail related transactions, including the emails, contacts, calendar entries, notes, journals etc. in a PST file. Similarly, MS Exchange Server is a server side application that allows you to configure a number of email accounts and provides options to manage them easily. Moreover, the Exchange Server database stores all the mail transactions in it. And that is why it has been a great option for organizations to host their own Exchange Servers rather than relying on third-party mail servers.

Now, discussing the significance of the OST files, when you go offline, your Outlook application makes an exact copy of your mailbox on Exchange Server in your local computer as an OST file. The location of the OST file can be - C:\Documents and Settings\\Local Settings\Application Data\Microsoft\Outlook.

With OST files, you can access your mailboxes, make changes in it and the changes will take effect, when the Outlook will get connected to the Exchange Server. These OST files, not only allow accessing mailboxes in conditions of limited or unreliable networks, but helps in recovering mail items in cases of any trouble. Below are some of the instances, when your locally stored OST files can be immensely helpful in restoring your mail components:

-Mailbox got deleted or migrated from the Exchange Server
-The Exchange Server database has been corrupt
-Exchange Server has been down for long or got crashed
-Damage or modification to the Exchange profile
-The name of the mail server has been changed

In any of the above situations, you can take the help of any OST to PST converter utility and convert the OST file into equivalent PST. This PST file can be easily imported into the Outlook and you will get your mail items back.

Perform OST file recovery for Error [0x80040111-00000000-00000000]

Accessing Microsoft Outlook in the offline mode is a great relief for its users. The OST file so created rests on the local machine and contains all the emails, attachments, notes, calendar enties, journals and tasks created just the way they actually are onto the server.

Corruption in OST file:

Since, the OST file is stored on a user's system (either laptop or desktop), the vulnerabilities that the system is exposed to are also applicable to the user's OST file. Virus attack, data storage device failure, network connection failure, power failure and more such factors play a primo role in the corruption of Outlook OST file.

Once corrupted, the data that resides onto that file including vital emails, appointments and contacts become unusable. A frequent error that is encountered when sending emails is:

Click on Tools and then choose Email Accounts.
Edit the existing account.
For Exchange users, click on 'More Settings...' button at the bottom.
