Hi,

Thanks for the suggestions, found that the problem is related to a control
in the form and not related to the redemption coding.

Are you sure it really hangs rather than return error that your code does

What is different between these two apps? Are they regular UI apps?

I have two applications developed in Visual Basic. Both the applications
use
REDEMPTION to communicate with EXCHANGE SERVER. The main application just
hangs when the following command is executed, whereas the same command is
executed perfectly fine with the second application.

Call oRDOSession.LogonExchangeMailbox(ExchangeId, ExchangeServer)

Can anyone suggest or help, to resolve the problem.

Thanks in advance for the help.
