Microsoft Outlook may be the most widely used email service around the globe, but users have come to accept the good with the very bad. Yes, Outlook offers an extensive and exclusive range of features as well as its friendly user experience. But there’s the flip side: User forums are filled with anger over errors that seem to have zero solutions. For this article, we will examine and hopefully resolve perhaps the most common Outlook error: “cannot open your default email folders.” This Outlook error mostly appears when you are trying to open your Outlook profile. It generally happens because of a corrupted OST file or the execution of Outlook in compatibility mode.
OST files are the files that allow users to use Outlook while they are offline. It is actually a synchronized copied element of the accounts saved on your device that enables you to continue to use Outlook even when the program gets disconnected from MS Exchange Server.
These files can become corrupted because of various reasons. Some of the reasons are:
Here’s some ways to begin fixing the problem:
You might have witnessed these errors:
“Cannot open your default email folders. Information store could not be opened,”
“Cannot start Microsoft Outlook. Cannot open the Outlook window. The server is not available. Contact your administrator if this condition persists.”
“Cannot display the folder. File access is denied. You do not have the permission required to access the file C:\Users\username\localsettings\application data\microsoft\outlook\outlook.ost”
If you have enabled compatibility mode mistakenly, just disable it. If you haven’t, do not enable it for Outlook. Users typically enable it when they are required to run the troubleshoot compatibility wizard. Also, compatibility mode is not required for any version of Outlook on Vista or Windows 7 or any other Windows OS. This mode is also not needed for any application that is supported on any Windows OS or for recently released applications.
The user can switch off compatibility mode in a 64-bit operating system by following these easy steps:
And in case, you are unable to place the Compatibility tab, follow the following steps:
If this issue is experienced over an Exchange email account that is configured on your Outlook, you can diagnose the error by trying the following steps:
