Well this discussion continued on the VM communities forum but was just closed by a moderator on that forum - stating that all business internet problems should only be discussed on the phone! Well I don't think he can censor discussion here.

As an update I can confirm that reducing the MTU size in our router has solved the Exchange problem we also encountered after installation (although it was not evident at first).

I since had a call returned from Business Faults who tried to tell me to do the very same fix, i.e. to set the MTU value in the email server or the router (if you have one) depending on type of setup. They were not quite clear as to the best value to use, but something under 1460 was advised.

The guy also told me they had a new version of firmware was being tested "next week". He did not know how it fixes having this restricted MTU (I found most PPPoE networks use 1492) but said they were working on this issue and also some other issue with the tunnel dropping occasionally.
