Re: Will Exchange 2007 help with delays
First thing I would try is downloading and running ExBPA against your

Re: Will Exchange 2007 help with delays
Thanks John
Also in moving forward what features in the new Exchange would eliminate
this issue. At the moment we are looking into moving to the new Exchange but
want to make sure when we do we do not run up against the same issue. Thanks
