Hi Paul,
That would be a "No" on the users siting on the lap situation.,.. 
I have users that have access to 2 different email accounts. They have there own company account and also they work for the helpdesk which has its own account. So for these particular users they need to connect to 2 accounts at the same time. I ended up re-writing the assembly so that it can be logged into exchange with multiple accounts and so far it seems to be working, not sure if that would be the "standard/correct" approach or your suggestion of Threadsafe pragma would be the better approach.. any thoughts on that?
Anyway thanks for the reply.
Dave V.
