4. Creating a New Outlook Profile

A corrupt Outlook profile causes this sending reported error (0x8004010f). Creating a new profile sometimes helps:

Add a new profile and choose Manually configure server settings or additional server types.
The Choose Service dialog box will appear. Select Internet E-mail and enter your email account information.
Next, click Test Account Settings to put your account through its paces.
Select your existing data file.

Open Control Panel > Mail > Email Accounts.
Select your email account, click Change > More Settings > Advanced. Uncheck the Download Shared Folders option and save your changes.
Then, launch Outlook and verify that it is operational.
Otherwise, go to the Advanced tab and Uncheck Use Cached Exchange Mode.
After that, apply the changes and restart Outlook
