Understanding Outlook Error Code 0x8004060C:

Outlook Error Code 0x8004060C is typically associated with a storage limit issue. The error message often reads: “The message store has reached its maximum size. To reduce the amount of data in this message store, select some items that you no longer need, and permanently (SHIFT + DEL) delete them.” This error occurs when your Outlook data file (PST or OST) approaches or exceeds its maximum storage capacity, preventing the smooth delivery and reception of emails.

Solution 1: Delete Unnecessary Emails and Attachments:

The error message itself suggests reducing the amount of data in your Outlook message store. Start by identifying and deleting emails and attachments that are no longer needed. You can sort your emails by size to identify larger attachments that may be consuming considerable space. Deleting unnecessary data will free up storage space and can help resolve the error.

Solution 2: Archive Old Emails:

Outlook provides an archiving feature that allows you to move older emails and items to an archive folder, reducing the size of your primary data file. Archiving not only frees up space but also helps you organize your mailbox effectively. To archive emails, go to the “File” menu, select “Options,” then choose “Advanced.” Under the “AutoArchive” section, configure your settings and click “OK” to initiate the archiving process.

Solution 3: Compact Outlook Data File:

Outlook has a built-in tool to compact your data file and recover unused space, which can help fix the ms outlook error 0x8004060C. To access this feature, go to the “File” menu, select “Account Settings,” and then click on “Data Files.” Choose your data file and click on the “Settings” button. In the “Outlook Data File” dialog box, click on “Compact Now” to initiate the compacting process.

Solution 4: Repair Outlook Data File:

If the error persists, your Outlook data file may be corrupted. Outlook provides a “Scanpst” tool (Inbox Repair Tool) to repair corrupted data files. Locate the “scanpst.exe” file on your system (usually found in the Office installation directory), run it, and browse to select your data file (PST or OST). Click on “Start” to initiate the scanning and repair process. Once the repair is complete, restart Outlook and check if the error is resolved.

Solution 5: Create a New Outlook Profile:

In some cases, the error may be related to a corrupted Outlook profile. Creating a new profile can help resolve the issue. Go to the “Control Panel,” select “Mail,” and click on “Show Profiles.” Create a new profile and set it as the default. Open Outlook with the new profile and check if the error persists. If the error is gone, you can import your old data to the new profile.
