‘0x8004010f: Outlook data file cannot be accessed’ or ‘the operation failed, an object could not be found’. The error message occurs when your email profile in Microsoft Outlook 2010 is configured incorrectly (incorrect Microsoft Outlook setup in other words). Check the below mentioned free Microsoft Outlook support guide and fix your Microsoft Outlook problem.
Close Microsoft Outlook. Also, exit MSN or Windows Messenger if it is currently running. Now click the Start button and navigate to Control Panel. Look for Mail and double-click it. When in the Mail Setup-Outlook window, click the Show Profiles button. This will take you to the email profile dialog box. Click to select your email profile (if there are many) and hit the Properties button. Click the Data Files button in the next window.
When in Account Settings, click to highlight the Data Files tab. Note down the name as well as the path of the data file shown under there. This is the default data file (with a check mark beside it) that stores your email profile data. Now click the E-mail tab, select your email profile, and click the Remove button. Confirm the action if prompted. When done, close the window by clicking the Close button at the bottom right hand corner.
Now that you have the details of your email profile, create a new one. Click the Start button and navigate to Control Panel> Mail. When in Mail Setup-Outlook window, click Show Profiles. Click the Add button in the next window. It will take you to the Add New Account dialog box. If you want Outlook to automatically create and configure your email profile, fill in the required details like name, email address, and password etc. and hit the Next button.
If you want to manually configure the settings, do not fill in anything and just click the button next to Manually configure server settings or additional server types. Hit the Next button to continue. Click the Internet E-mail button and hit Next. When in the Internet E-mail Settings window, enter the required details like name, email address, correctly (do not misspell) in the relevant fields. Choose your server type from the drop-down arrow beside Account Type.
Enter the incoming and outgoing server information, username and password in the relevant fields, and check the Remember Password box. Click the More Settings button. Click the Advanced tab. Enter the port numbers for incoming and outgoing mail servers. Check the box next to This server requires an encrypted connection (SSL) under the Incoming server (POP3). Leave the default option (None) selected beside Use the following type of encrypted connection.
Adjust the server timeout to the maximum level. Check the box Leave a copy of messages on the server if you want your webmail account to retain a copy of email messages. If you do not check this option, all your emails will be downloaded to Microsoft Outlook and your webmail account will have nothing. When done, click the OK button. You will return to the Internet E-mail Settings window.
Click the Test Account Settings button to test your new email profile settings. If all goes well, you will see a congratulations message. Click the Finish button to exit the window and enter Outlook. If the test returns an error message, look in to it and launch troubleshooting. Check back your account settings and correct them if required. If you are not sure of the details, contact your internet service provider and take all the required information.
Once the correct email account is set up, configure it as the default email profile. To do so, go back to the Mail Setup-Outlook window (check the first step). Click the button next to Always use this profile and select Outlook from the drop-down arrow below. Click the Apply button and then OK to apply the changes and exit the window. Close and reopen Outlook. When done, either send or receive emails or use Outlook as desired.
The error may also be related to the Offline Address Book or an Outlook profile which is not a domain member. Contact your Exchange server or IT administrator to fix this problem. If the problem persists, contact Microsoft Outlook support.
