Urgency
Medium
Quick answer
Outlook cannot send or receive and shows 0x8004010F. Microsoft puts it down to a damaged Outlook profile: find your default data file first, then create a new profile that uses it.
Safety first
Stop and check this first
- Do not delete the old profile or its .pst file until the new profile sends, receives and shows your old mail.
- Microsoft documents this procedure for Outlook 2010 and Outlook 2013 with IMAP or POP3 accounts; in other versions menus may differ.
Safe checks you can perform
- Location of the default data file
- New profile with auto account setup
- Manual profile with the existing data file
- New profile as default
Leave these tasks to a qualified professional
- Do not attempt this professional task: Create the manual profile and verify the account
- Do not attempt this professional task: Confirm the old mail is still reachable

What it means
Microsoft documents 0x8004010F when sending or receiving mail in Outlook 2010 and Outlook 2013, with messages that the Outlook data file cannot be accessed or that an object could not be found. It attributes it to a corrupted Outlook profile, not to the mailbox or server.
