Is this code running against Outlook connected to an Exchange server? If so
it's possible the code is running into the 255 open RPC channel limit that's
the default for Exchange. That limit can only be changed in the registry of
the Exchange server.
What happens is that an RPC channel is opened for every Outlook object
reference. If you are opening an item that opens a channel. If you access a
property on the item that can open a channel. Use of dot operators opens
internal variable objects that aren't released until the loop ends or the
procedure exits.
I don't know your code but it's possible that's the problem. In that case
make sure that you explicitly declare variables for each dot operator and
release all objects instantiated within any loops by setting them to Nothing
each pass through the loop.
