Navision and Exchange

HI ALL, I’m using Nav 3.70. Is it possible to make Navision Synchronize with Outlook calendar of more than ne salesperson per session. I mean… Now Navision synchronize the to-dos using all the data from the salesperson card. But, before all, it verifiies the Navision User ID to recognize who is currently logged in and start the synchronization process for only the currently logged in salesperson. I would need to log in as a salesperson with the right to make/modify to-dos in the outlook calendar, create to-dos for me or for other salesperson, and have navision that synchronize with the other salesperson calendar. Please, Help me!!! Bye HAI
