The first version was called Exchange Server 4.0, to position it as the successor to the related Microsoft Mail 3.5. Exchange initially used the X.400 directory service but switched to Active Directory later. Until version 5.0 it came bundled with an email client called Microsoft Exchange Client. This was discontinued in favor of Microsoft Outlook.

Several scenes involving harvesting potatoes don't seem at all realistic, even to a city boy like myself. In one scene, Martin Senior (Kurt Russell) harrows a field which supposedly hasn't been harvested. He has a nice John Deere tractor, but can't afford even a simple potato harvester for a farm worth over a million dollars, which means it is probably over 400 acres. The potato stalks are missing. How they removed the stalks without harvesting the potatoes is the biggest mystery in the film. But three guys manage to harvest 400 acres of potatoes in an afternoon. The potatoes have no dirt clinging to them when they are harvested. It really looks as if somebody took a couple of sacks of potatoes and covered them with a little dirt in a freshly ploughed field. If harvesting potatoes is a significant plot element, producers really need to schedule production in the fall, rather than the spring.

“The arguments have devolved over three or four years of bitter debate, the principles are real and they are important to preserve, but a lot of the drama has nothing to do with principles anymore. A lot of this debate is now more about hurt feelings. It’s about bruised egos. It’s about things that were said that can’t be unsaid, insults that were exchanged, and personalities and ego.”
The current version, Exchange Server 2019,[2] was released in October 2018. Unlike other Office Server 2019 products such as SharePoint and Skype for Business, Exchange Server 2019 can only be deployed on Windows Server 2019. One of the key features of the new release is that Exchange Server can be deployed onto Windows Server Core for the first time, additionally Microsoft has retired the Unified Messaging feature of Exchange, meaning that Skype for Business on-premises customers will have to use alternative solutions for voicemail, such as Azure cloud voicemail. Unified Messaging continues to exist in Exchange Online requiring an Exchange Plan 2 license.

Exchange Server Enterprise Edition supports clustering of up to 4 nodes when using Windows 2000 Server, and up to 8 nodes with Windows Server 2003. Exchange Server 2003 also introduced active-active clustering, but for two-node clusters only. In this setup, both servers in the cluster are allowed to be active simultaneously. This is opposed to Exchange's more common active-passive mode in which the failover servers in any cluster node cannot be used at all while their corresponding home servers are active. They must wait, inactive, for the home servers in the node to fail. Subsequent performance issues with active-active mode have led Microsoft to recommend that it should no longer be used.[3] In fact, support for active-active mode clustering has been discontinued with Exchange Server 2007.
At the time of the software upgrade (also known as a fork) anyone owning bitcoin was also in possession of the same number of Bitcoin Cash units.[19][16] The technical difference between Bitcoin Cash and Bitcoin is that Bitcoin Cash allows larger blocks in its blockchain than Bitcoin, which in theory allows it to process more transactions per second.[20] Bitcoin Cash was the first of the Bitcoin forks, in which software-development teams modified the original Bitcoin computer code and released coins with “Bitcoin" in their names, with "the goal of creating money out of thin air."[21] In relation to Bitcoin it is characterized variously as a spin-off,[5] a strand,[22] a product of a hard fork,[23] an offshoot,[24] a clone,[15] a second version[14] or an altcoin. On 1 August 2017 Bitcoin Cash began trading at about $240, while bitcoin traded at about $2,700.[16]
