Hello !

I'm making a program that do a sincronizattion with MS Outlook e-mails and I
have a problem.

When the program starts the download of the messages, it stops with an alert
saying 'A external program is trying to access e-mails stored in outlook'.
Not exactly it because my outllook is in portugueses.

Anybody know how to avoid this blockade ?

Best regards

Umeoka
