Mail sent from DWA is not saved in Sent folder

It has been asked before, but I haven’t found any posted solution.

It happens to only 1 user (other work fine):

-Send mail from Domino Web Access

Either with ‘Send’ or ‘Send & Save’

-Sent mail does NOT appear in ‘Sent’,

nor in any choosen folder, if we check from DWA.

-Sent mail appears in Sent folder or selected folder if we access the database from a Notes client.

How can it be fixed, so this user can see his sent mail from Domino Web Access?

Thanks a log,
