Outlook Error 0x08004010F

Outlook Error 0x08004010F

Outlook Error 0x08004010F relates to a problem while sending emails, the account could be either IMAP or POP but using SMTP to send the outgoing email. The problem is in the PST/OST file used for processing the SMTP outward bound mail.

It’s often a result of moving the PST files from their default locations, but other profile issues can cause this error too.
(Note, it can also occur while synchronizing OAB for exchange users)

POP

For POP users, the workaround is to create a new dummy PST file and temporarily set it as the default INBOX, then revert the settings back to the original file

IMAP

For IMAP users, you can’t change the INBOX folder so here are some other options:

1. Create a new profile and set as default. This is the official Microsoft line and works, but can be a massive pain if you have multiple accounts and lots of specific configurations set up, like I do.
2. Use SCANPST to check the outgoing PST file – might be something that the SCAN tool can fix, but if you have been able to get into the PST in the first place, it’s unlikely to be corrupted.
3. Run the Compact option on all the PST files, it’s not worked for me but a few posts I have seen have suggested it does work.
4. Recreate the email accounts one-by-one, not the entire profile, just go onto the email tab and add each email again. I have not tried this yet, but I imagine it will recreate the PST files in the default location.
5. VONAH suggested a registry fix on the technet forums here that actually worked for us (though not for the novices, it requires delving into the registry and editing in HEX)
   1. Open HKEY_USERS
   2. Open the USER folder – this will be the long one that starts S-1-5-21- and doesn’t end in _CLASSES
   3. SOFTWARE > MICROSOFT > WINDOWS NT > CURRENTVERSION > WINDOWS MESSAGING SUBSYSTEM > PROFILES
   4. BACKUP THE REGKEYS AT THIS POINT!!!! so if something goes wrong, you don’t loose your profile
   5. Open the folder with your outlook profile name
   6. Open the folder 9375CFF0413111d3B88A00104B2A6676
   7. Look through the subfolders for the one(s) containing the REG_BINARY entry “Delivery Store EnteryID” (There will be one for each IMAP address you have)
   8. Edit the “Delivery Store EnteryID”
      1. You’ll notice it’s in HEX with a readable version on the right.
      2. Edit the end of the entry to point to the correct PST file
      3. Note that between each character there is a null ’00’ represented by a period, but it is NOT the period character
   9. Save the changes for each folder then open outlook and test SEND/RECEIVE
