I use Outlook 2007 and for some reason from time to time there are significant delays from transmission to receipt of mesages. Today is an example. Messages sent at 9:00 a.m. and earlier were not received until 6:00 p.m. or later. What cauess such delays? Anything I can do to prevent delays? I also find messages stuck in my outbox which is a different problem I guess. Thanks for any info you can offer ... or solutions. I only saw one post about this from someone else, but no reply.
