Re: Getting the updated unread message count...

Question

I assume you're opening the folder read/write.
The IMAP protocol may allow the behavior here to be server-dependent.
What IMAP server are you using?

Answer 1

I did run a protocol trace.
I started the 2nd program mid-way the 1st program had run. The protocol traces they both generated were identical (with no difference at ALL!!)
Here is the trace (I could not make much of it :( )
