MS Outlook is one of the well-organized email clients in many corporate organizations. This application enables the usage of mail accounts in offline mode by creating the OST file. It is very favorable for Outlook users to securely carry out remote access emails & other mail attributes from their mail accounts.

Microsoft Outlook 2016 has included many advanced features that were not present in its previous versions. But, while using the Microsoft Exchange Server OST file many users have come across the error message saying that your Outlook Data file has not been configured. With this error message, the users are unable to figure out what triggers this error message. So, let us know in short about the error message data file (.pst & .ost) in Outlook that cannot be configured.

What Does the “Your Outlook Data File Cannot Be Configured” Error Mean?

When MS Outlook says: “your data file cannot be configured”, it indicates MS Outlook is unable to associate a mailbox with the required data file. As we know that MS Outlook stores its data in three of its proprietary file formats:

• PST: Personal Storage Table file primarily for archived mail and POP accounts.
• OST: Offline Storage Table file used for Office 365 and MS Exchange accounts.
• NST: Storage file used for Outlook groups and shared data.

Now, the problem is if Outlook fails to configure one of these files correctly then, the application will fail to load the mailbox profile and will ultimately show the configuration error.

What Causes the Outlook Data File Configuration Error?

• The most common reason for your Outlook Data cannot be configured including missing OST & PST files on the system where MS Outlook is running.
• If the system gets crashed while importing data files in Outlook, then the process will get dismissed & Outlook may not configure the profile which you are looking for.
• Moreover, when the OST & PST file gets corrupted due to a virus attack, logical error, synchronization error, abrupt termination, etc. It can display this error message “Your Outlook Data File Cannot Be Configured” when the users try to access their Outlook profile again.
