Outlook data file cannot be accessed error is one very common error. The worst part is you don’t know how to deal with the error.However, you don’t need to worry. In this article, I’ll explain you briefly that How to Fix Output Data File Cannot be Accessed error.
While using MS Outlook while staying connected to the Exchange server, all the mailbox data present on the server is stored in a local file called Offline Storage Table (OST) file. This file can be seen as a replication of your Exchange mailbox as it locally stores all the records of the account available on the server.
The major role of this data file appears if the Exchange server experiences downtime, that may be due to maintenance as well as some technical issues, etc. When such things happen, you can continue to work with the OST file locally without being interrupted and any change you make to the account is joined with your Exchange account once the server starts running fine again.
However, sometimes you may encounter errors when trying to access your Exchange mailbox data through the OST file. These errors may occur due to a defective synchronization between Outlook and Exchange or, due to some other problems with the OST file. Often the problems within the OST file invoke mailbox access errors. Here, I am going to help you on a common OST error, 0x8004010F, and furthermore the methods to fix it.
