Leased line and hosted Exchange providers.

[The Griffalo]

Does anyone know of a decent (read more reliable than P1pex) provider of leased lines and hosted MS Exchange solutions?

One of my customers is hacked off with them and wants to move but I want to be certain any supplier I suggest will be an improvement on their current setup.

Does it have to be Microsoft Exchange hosting or do they just need IMAP/POP3/SMTP? Do they need things like private and shared Calendars/Contacts/Tasks/Notes accesible through Outlook? The reason I ask is that we have a hosted solution that may be suitable for them. However, we don't provide leased lines. You could try BT or Zen for the latter perhaps?

I work for NTT Europe, and they cover everything you're after.

though they don't mention hosted exchange on the site, they do offer it as a service
