Hi fmcrede,
>> when I configure the e-mail account that is used with a new and clean profile at the "e-mail" section at control panel
Have you ever configured this email account on the computer before?
If this is the case, this may happen because the newly created profile doesn’t “know” that these messages have been received before by another profile. To prevent this from happening, please make sure to start Outlook at least once with a clean pst-file
before reconnecting the old one and setting it as the default delivery location.
