Microsoft Outlook has become one of the most widely used applications in organizations for internal and external communication. When Cached Exchange Mode is enabled (while configured with IMAP or Exchange account), Outlook holds all the data of your Exchange mailbox on your hard disk in OST files. Outlook synchronizes the OST file with Exchange mailbox when the server is available.
On the Other hand, when you configure your Outlook profile with the POP account, then it will save your mailbox data in the PST format. Due to several factors users look to convert their files from the OST to PST. Let’s look at the factors that compel the users to do this conversion.
Why is it necessary to convert OST files to PST?
There are several reasons when it becomes necessary to convert an OST file to PST. Some of the reasons are:
- Sudden crash of MS Exchange Server due to power failure, virus attack, malicious software, or any other reason. If any such errors occur, then you won’t be able to connect with the MS Exchange Server to access your data.
- During the maintenance or downtime of the Exchange Server, you might not be able to access your mailboxes or synchronize OST files with Exchange. But sometimes, it becomes necessary to have access to Exchange mailboxes. So, at such times, you need to convert the OST file to PST to access those mailboxes.
- Converting OST files to PST will allow you to recover data even after accidental deletion of user mailboxes on the Exchange Server.
- By converting OST to PST, you can migrate Exchange data to other platforms, such as Office 365, Live Exchange, etc.
- There are always chances of OST corruption due to unexpected errors. So, it is a good idea to have a backup of that data by converting it to PST.
These points clearly define why you need to convert OST file to PST. Now, the question arises, how do you convert an OST file to PST?.
When it comes to converting an OST file to PST, there are two major manual methods available to execute this conversion. Here, we will elaborate on both these methods in detail.
