We see many complaints that Outlook crashes when replying to messages or creating new messages. This happens because the delivery folder selection is corrupt and you are referencing a nonexistent folder.
This should only affect POP3 email account and may be more common when the profile contains a Microsoft Exchange Server account.
- Open the Account Settings dialog. In Outlook 2010 and up, look on the File tab, in Outlook 2007, it's on the Tools menu.
- Select the POP3 account
- Click Change Folder
- Select a folder to deliver to.
- Work you way back out to Outlook and see if it still crashes.
Send and Receive Error: 0x8004010F
A missing or corrupt folder selection can also result in the following errors when attempting to send and receive. The fix is the same: click Change Folder and select a folder for delivery.
Task 'email@example.com - Sending' reported error (0x8004010F) : 'Outlook data file cannot be accessed.' Task 'firstname.lastname@example.org - Receiving' reported error (0x8004010F) : 'Outlook data file cannot be accessed.'
Note: when the error message is 'object cannot be found' and you use an Exchange mailbox, the 800x4010F error is the result of problems with the address book. See The Dreaded 0x8004010f – Operation Failed Error
