Exchange Protocols: Details

Overview Document: MS-OXPROTODefines protocol families Scenario-Based How protocols work togetherWalkthroughs andexamples Display an e-mailSend an attachmentCreate an appointment and other scenarios

Protocol Families ROP Protocols Originally RPC transport HTTPS transport introduced inExchange 2013 NSPI is used for Address Book access Exchange Web Services (EWS) ActiveSync (EAS) Other protocol groups Autodiscover Content Conversion Standards Support

Exchange Protocols: DetailsROP Protocols

History of terminology – what is “ROP”?Initial name: RPC protocols Remote Operations (ROPs) over RPC connectionRPC is just a channel to exchange binary blobs between client and serverThis binary blob can be transmitted by other underlying protocols RPC over TCP or RPC over HTTPS (MS-OXCRPC)Pure HTTPS (MS-OXCMAPIHTTP)MAPIHTTP is RPC replacement (Exchange Server 2013) The same binary blob is now transmitted over HTTP, bypassing RPCSince it’s not RPC anymore, we now call them ROP Protocols In many places it is still called “Exchange RPC protocols”, sometimes MAPI

ROP Protocols DetailsTransport layers: RPC/TCP, RPC/HTTPS or pure HTTPS Low-level access to Exchange Server Storage Optimized to minimize traffic on the wireVery complex parsingUsed by MAPI Major channel for Outlook for Windows Desktop communication with Exchange ServerOriginally implemented in Exchange 4.0 (first release of Exchange) Extended and re-architected several times

ROP Protocols DocumentationROPs protocols define both Server and Client behaviors Client behaviors are very complex Wrapped in MAPI implementation on Outlook for Windows DesktopClient performs logic to maintain complex items: Messages, Folders, Calendar, Contacts,Tasks, etc Document Naming: [MS-OXO*] and [MS-OXC*] Over 40 Protocols, 3000 pages

Example of complexity in ROP opIDROP DataBinary BlobROP2RopID HSOT TableROP DataNote: No ROP Data size or end marker.Every ROP Data in the blob must be parsed.Every RopID has different ROP Data structure.Number of documented RopIDs: 130

Where to start: ROP Protocols

ROP Protocols SummaryNot recommended for new applications due to complexity Modern Exchange Server has good alternatives Exchange Web Services for On-Prem ServerMicrosoft Graph for Exchange Online

Exchange Protocols: DetailsExchange Web Services (EWS)

EWS Protocols: DetailsAlternative to ROP protocols Higher level of abstraction compared with ROP protocols EWS implements messages, attachments, calendar events, contacts on server sideOutlook for Windows Desktop uses subset of EWS protocols Unified Messaging, MailTips, Availability, OOF, Office Apps, Room List, Archive, Mailbox Policies, Calendar Sharing,Site Mailboxes, etc.Intuitive/readable XML (easier troubleshooting)Transport: SOAP over HTTP(S)

EWS Protocols: DocumentationCode in any language/platform that supports HTTP/SOAP calls SDKs are available as wellDocument Naming: [MS-OXW*] 43 Protocols, 2000 pagesFirst implementation: Exchange Server 2007 New on-prem features tend to be implemented in EWS

Where to start: EWSNot hierarchical Start withMS-OXWSCORE

EWS SDKsExchange Web Services (EWS) Managed API WebServices/ https://github.com/OfficeDev/ews-managed-api ged-api-ews-and-web-services-in-exchange

EWS SummaryRecommended protocol for on-prem Exchange Server applications Legacy authentication only No OAUTHGRAPH/REST APIs is better alternative for Exchange Online andHybrid Exchange Server Modern authenticationSeamless integration with other services (SharePoint,OneDrive, Azure Active Directory, etc.)Future updates will happen in Microsoft Graph APIs

Exchange Protocols: DetailsExchange Active Sync (EAS)

Exchange ActiveSync: Protocols DetailsLightweight synchronization protocol for Exchange Server Optimized to work on high-latency and low-bandwidth networksDesigned to minimize device power usageHigh level of abstraction, similar to EWS in complexity Provides access to email, calendar, contacts, tasks, documents, etc.Transport Layer: WBXML over HTTPS Industry standard Several non-Exchange Server implementationsWide range of clients – iOS, Android, Windows, etc.

Exchange ActiveSync: Protocols DocumentationDocument Naming: [MS-AS*] 15 Protocols; 900 pagesFirst Implementation: Exchange Server 2003

SCALMS-ASDOCMS-ASCNTCMS-ASPROVWhere to start: Exchange ActiveSync

Typical Usage of Exchange ActiveSyncMobile Applications Tablets and lightweight desktop applications Additional considerations Allows for low-bandwidth and high-latency data (Internet) connections while scalingreasonably on high-speed connections.Not feature parity with Exchange ROPs and Web Service (EWS) protocolsLicensing requirementsMicrosoft Graph APIs should be considered as betteralternative for Exchange online

Choice of Protocols to Use

On-Premises choiceEWS is recommended for new applications ROPs protocols are very complex EAS has special purpose Hybrid mode brings on-line richness to on-prem implementations

Exchange Online has more If you develop for Exchange Online, consider Microsoft Graph APIs //aka.ms/30DaysMSGraph

Exchange Server 2016 takes advantage of this with a primary design goal of simplicity in scale and hardware utilization. The number of server roles has been reduced to two: Mailbox server and Edge Transport server. The Exchange Server 2016 Mailbox server role includes all server components from Exchange 2013 Mailbox and Client Access roles:

When provisioning a Windows Server for a specific role there are additional items to consider for further securing the server. When planning and provisioning your server layout, designate one primary purpose per server. Whenever possible, designate one server as the database server, one server as the web server, and one server as the file server.
