Ted suggested that I post here as I find more issues with using Gnus
with Exchange 2007.

If I move an email between IMAP folders ('B m'), I get the following messages:

Registry: Registering article 6 with group nnimap+exchange-d01:INBOX/Development/gnu
Registry: Registering article 7 with group nnimap+exchange-d01:INBOX/Development/gnu
Moving to nnimap+exchange-d01:INBOX/Development/CVS: (6)...
nnimap-request-move-article: this is an internal move
The specified message set is invalid.
Couldn't Move article 6: The specified message set is invalid.
nnimap: Updating info for nnimap+exchange-d01:INBOX/Development/gnu...
nnimap: Updating info for nnimap+exchange-d01:INBOX/Development/gnu...done

The message is, in fact, copied between the 'gnu' folder and the 'CVS'
folder but it is not deleted from the 'gnu' folder.

I am attaching the output of the imap-debug buffer showing everything starting
with pressing 'B m'.

Thanks for any help anyone can provide.
