The problems related to “.ost file/Offline Data file” of MS Outlook, during its execution time. You will find out the way to recreate OST file or offline data file. It also expresses that what an OST File is and how it helps users during offline mode.
Concept of offline data file/.ost file:
OST is a file format for the offline data file of Microsoft Outlook. It stands out for “Offline Storage table”. As the name suggests it is an offline folder file which stores synchronized the copy of the information on your local system/computer.
Imagine yourself on a plain or on a yacht, where there is no data connection and you want to access your e-mails, calendar, tasks, and contacts than you can still access them. If you are curious that how is it even possible?
Then answer is that all your IMAP accounts, Office 365 accounts, Exchange accounts, and Outlook.com accounts use an Offline Outlook Data File (.ost) file where they store data offline.
But you can use only previously downloaded data. And when the connection is back it will automatically do all the changes over server data, done on the offline file.
Issues with ost files:
OST files resemble our mailbox server data during no connection period. OST file is stored over our personal system so this becomes the vulnerable amount of data, which can be harmed any time.
It originates multiple errors from time to time like:
- Corrupt OST.
- Synchronization issues.
- Inaccessible OST.
There are multiple reasons for ost file corruption. These could be multiple reasons for your problem like:
- Deletion of user account over Exchange Server.
- Malicious files (virus attack).
- Abrupt termination of applications.
- System Crash.
- Interrupted power supply.
Methods to Recreate OST file:
Outlook is embedded with some tools which aid us to restore OST file. Versions of Microsoft Outlook got the different type of tools to restore OST file, like
|Version(MS Outlook)||Tool (As per the version)|

|Outlook 2003||Detect and Repair Tool|

“Outlook 2013/2016/2018/2019 got a different method of exporting mailbox as a PST file and saving OST data to PST file also.”
Another Method to recreate OST file is mentioned down, where you can directly download it from the mail server by following further steps:

- By right-click you will find delete option, what you need to is to delete the ost file.
- Again Run Outlook application, hope it will resolve the ost file problem.
As I told you that ost files are stored at our system (Client-side) and contain the synchronized information of our outlook mail server to help us out in the situation of network loss between the system and the mail server. The Reason for their vulnerability is that they are on the client side so it’s not safe for them and leads to errors and failures. I also discussed some effective methods to help you to recreate OST file. If there is an issue still remaining then you can go for any third party app. I prefer “OST File Recovery“ to solve my issues in the worst case, so you can also go for that.
