George:
Sorry - something has gone wrong with my posts. I added the output of testconnectivity a couple days ago - and didn't notice it never posted,. I just did it again and replaced what I think is missing,.
This is the cache setting and I am surprised you unaware of the problems this is causing. Earlier in this thread I placed two links regarding this issue - I think you even took part.
These are settings on my email at work - and even set at 12 months mine works. Doug's won't function at all on either account if set > one month.
