Hallo, Following my cry for help earlier, I have taken the advantage of being down to convince the management that we need to purchase new Exchange software.. And it worked... :-) I currently have Exchange 5.5 Standard running on NT4. I also have 150 Exch 5.5 CALs. All Clients are Outlook 2000 or XP. We will be installing a brand new Win2K server on a new Win2K domain and install Exch 2k Enterprise on that. I want to have both Exch 5.5 and 2k running in parallel for some time (probably 1 or 2 months) until I move all the mailboxes across and iron out any problems. After explaining to my supplier what I need, I have a quotation for the following 2 items: 312-01580 Ms Exchange Upg / Adv OLP NL 381-01367 Ms Exchange CAL Upd / Adv OLP NL Does the above tell you anything if it is the Enterprise version of exchange? All I can see is the 'UPG' for upgrade. Does ADV = Advanced = Enterprise? Will we be able to use the media we will buy for Exch 2k to install it on a clean server, or is it just suitable for an inplace upgrade?
