I'm sorry to drag this one out, but I'm still having some trouble with it...
If I use the command:
tag LIST "" "*"
then Exchange 2003 will report amongst its other entries the following
item:
* LIST (\\Noselect) "/" "Public Folders/"
I still don't really understand why the trailing delimiter is required when
"\Noinferiors" is not present, but I'm just thick so we'll leave it at that -
I've already coded around it.
If, however, I use this command:
tag LIST "" "%"
Then the "Public folders/" entry is not returned. Now, if the trailing
hierarchy delimiter is actually part of the item's name, then I guess it's
correct for it to be suppressed because '%' won't match a hierarchy
delimiter.
The problem is that this makes it *very* hard to be a "good citizen" and
use '%' to enumerate only the levels of hierarchy you actually need at
any given time, because the public folders entry won't be available to
you if you do things that way.
In fact, if I use '%' wildcards to retrieve folder lists, I can't see any way at
all of ever getting to the "Public folders/" tree - I've tried passing "Public
folders" and "Public folders/" as a reference, but Exchange simply
returns no items when I do this. It seems I can only get the public folder
structure by using a '*' wildcard.
I'm sure this is all being done by design, but I'd be grateful if someone
could clarify that for me... I'm currently completely rewriting the IMAP
code in my client to be better-behaved and more efficient, part of which
entails using '%' instead of '*' to reduce LIST command clutter. If I do
this, though, I can see myself getting a lot of tech support questions
from Exchange users wondering why they can't see any public folders,
and I'd like to know what the proper answer to give them is.
Cheers!
