Editing Microsoft Exchange Server (section)

==Clients==<!--Microsoft Exchange Client redirects here-->
Microsoft Exchange Server uses a [[proprietary protocol|proprietary]] [[remote procedure call]] (RPC) protocol called [[MAPI|MAPI/RPC]],<ref name=exchangeprotocols/> which was designed to be used by [[Microsoft Outlook]]. Clients capable of using the proprietary features of Exchange Server include [[Evolution (software)|Evolution]],<ref name=gnome/> [[Hiri (email client)|Hiri]] and Microsoft Outlook. [[Mozilla Thunderbird|Thunderbird]] can access Exchange server via the Owl Plugin.<ref>{{Cite web|url=https://www.beonex.com/owl/|title=Owl for Exchange|last=Beonex|website=Owl for Exchange|language=en|access-date=2020-02-21}}</ref>

Exchange Web Services (EWS), an alternative to the MAPI protocol, is a documented [[SOAP]]-based protocol introduced with Exchange Server 2007. Exchange Web Services is used by the latest version of [[Microsoft Entourage]] for Mac and Microsoft Outlook for Mac - since the release of [[Mac OS X Snow Leopard]] Mac computers running OS X include some support for this technology via Apple's Mail application.

E-mail hosted on an Exchange Server can also be accessed using [[Post Office Protocol|POP3]], and [[Internet Message Access Protocol|IMAP4]] protocols, using clients such as [[Windows Live Mail]], [[Mozilla Thunderbird]], and [[Lotus Notes]]. These protocols must be enabled on the server. Exchange Server mailboxes can also be accessed through a web browser, using [[Outlook Web App]] (OWA). Exchange Server 2003 also featured a version of OWA for [[mobile device]]s, called Outlook Mobile Access (OMA).

Microsoft Exchange Server up to version 5.0 came bundled with Microsoft Exchange Client as the email client. After version 5.0, this was replaced by Microsoft Outlook, bundled as part of [[Microsoft Office 97]] and later.<ref name=what_is>{{cite web |url=http://www.indiana.edu/~uits/telecom/messaging/whatexchange.html |title=What is the Microsoft Exchange client?}}</ref> When Outlook 97 was released, Exchange Client 5.0 was still in development and to be later released as part of Exchange Server 5.0, primarily because Outlook was only available for Windows. Later, in Exchange Server 5.5, Exchange Client was removed and Outlook was made the only Exchange client. As part of Exchange Server 5.5, Outlook was released for other platforms.

The original [[Windows 95]] "Inbox" client also used MAPI and was called "Microsoft Exchange". A stripped-down version of the Exchange Client that does not have support for Exchange Server was released as [[Windows Messaging]] to avoid confusion; it was included with [[Windows 95 OSR2]], [[Windows 98]], and [[Windows NT 4]]. It was discontinued because of the move to email standards such as SMTP, IMAP, and POP3, all of which [[Outlook Express]] supports better than Windows Messaging.

===Exchange ActiveSync===
Support for [[Exchange ActiveSync]] (EAS) was added to Microsoft Exchange Server 2003. It allows a compliant device such as a [[Windows Mobile]] device or [[smartphone]] to securely synchronize mail, contacts and other data directly with an Exchange server and has become a popular mobile access standard for businesses due to support from companies like [[Nokia]] and [[Apple Inc.]]<ref name=aslicensee/> as well as its device security and compliance features.

Support for [[push email]] was added to it with Exchange Server 2003 Service Pack 2 and is supported by Windows Phone 7,<ref name=asfaq/> the [[iPhone]] and [[Android (operating system)|Android]] phones,<ref name=iphone/> but notably not for [[Apple Inc.|Apple]]'s native [[Mail (Apple)|Mail]] app on [[macOS]].

Exchange ActiveSync Policies allow administrators to control which devices can connect to the organization, remotely deactivate features, and remotely wipe lost or stolen devices.<ref name=activesync/>
