FWIW, I've had experience of this problem from a different angle: I've
taken my server through considerable redevelopment recently, paying
particular attention to allowing multiple simultaneous connections to an
account. I had a similar problem where I was removing the message too
early, and it *did* cause some problems (I seem to recall that one of
them led to Outlook munging its cache, requiring it to be cleared). I
modified the code to defer the remove until a safe time and the
problems went away.
I wouldn't necessarily assume that you could rely on behaviour like this
being benign, *unless* you don't support multiple simultaneous
connections.
Cheers!
