In this article, we will discuss the causes of Outlook error 0x8004010F and how to fix it. We will also explore how to prevent this error from occurring again. Before we begin, you have to understand how Outlook operates and why Outlook’s data files, commonly known as OST (Offline Storage Files) and PST (Personal Storage Table), are essential for sending or receiving an email.
What are these Outlook data files, and why are they so important?
An Outlook data file (PST) or Offline Outlook Data File (OST) contains all your emails and other important information required for Outlook to properly display your messages. When you add an email account to Outlook, all your email messages are downloaded and stored in these data files. These files act like an offline copy of all your mailbox information, which is stored on the email server. Now, why are they so important? Well, these files contain all your mailbox information, and if these files are corrupted or not working as intended, then Outlook will be stuck in a loop and won’t know where to store more email information. This is because these files contain all the email messages you send or receive. That’s why the ‘Outlook data file cannot be accessed’ error appears. There are many other errors related to PST and OST files as well. Two more errors are often faced alongside this error if the Outlook data file is corrupted:
