<8> Section 3.1.4.1: Exchange 2010, Exchange 2013, Exchange 2016, and Exchange 2019 do not support Session Context linking. If the value of the ulIcxrLink parameter is not 0xFFFFFFFF, the server will not attempt to search for a session with the same Session Context and link to them. It will then return the same value in the pulTimeStamp parameter that was passed in.

<9> Section 3.1.4.1: In Exchange 2003 and the initial release version of Exchange 2007, the server counts individual connections for CAL accounting, so Session Context linking is useful in a call to the EcDoConnectEx method on the EMSMDB interface.

<10> Section 3.1.4.1: Exchange 2010, Exchange 2013, Exchange 2016, and Exchange 2019 do not support Session Context linking.

<11> Section 3.1.4.1: Exchange 2010, Exchange 2013, Exchange 2016, and Exchange 2019 do not support Session Context linking. If the ulIcxrLink parameter is not 0xFFFFFFFF, the server will not attempt to search for a session with the same Session Context and link to it. Rather, it will then return the same value in the pulTimeStamp parameter that was passed in.

<12> Section 3.1.4.1: Exchange 2007 does not fail when the value of the cbAuxIn parameter on input is larger than 0x00001008.

<13> Section 3.1.4.1: If the cbAuxIn parameter is greater than 0x00000000 and less than 0x00000008, Exchange 2007 does not fail, the initial release version of Exchange 2010 will fail with ecInvalidParam (0x80070057).

<14> Section 3.1.4.1: Exchange 2003 and Exchange 2007 return ecRpcAuthentication (0x000004B6) if the authentication context associated with the binding handle does not have enough privilege and if the szUserDn parameter is not empty. If the szUserDN parameter is empty, Exchange 2003 and Exchange 2007 return ecNone (0x00000000).

<15> Section 3.1.4.1.2.1: Exchange 2010, Exchange 2013, Exchange 2016, and Exchange 2019 do not support sending the AUX_OSVERSIONINFO auxiliary block.

<16> Section 3.1.4.1.2.1: Exchange 2003 and Office Outlook 2003 do not support the AUX_SERVER_SESSION_INFO auxiliary block.

<17> Section 3.1.4.2: Exchange 2010 returns the same value on output as was input, not 0x00000000.

<18> Section 3.1.4.2: Exchange 2003, Exchange 2007 and Exchange 2010 will fail with error code ecRpcFormat (0x000004B6) if the request buffer is larger than 0x00008007 bytes in size. Microsoft Exchange Server 2010 Service Pack 2 (SP2), Microsoft Exchange Server 2013 Service Pack 1 (SP1), and Exchange 2016 will fail with error code ecRpcFailed (0x80040115) if the request buffer is larger than 0x00008007 bytes in size.

<19> Section 3.1.4.2: Exchange 2003, Exchange 2007, and Microsoft Exchange Server 2010 Service Pack 1 (SP1) fail with error code ecRpcFormat (0x000004B6) if the value in the cbIn parameter is less than 0x00000008. The initial release version of Exchange 2010 will not allow a cbIn parameter value smaller than 0x00000008.

<20> Section 3.1.4.2: Exchange 2003 and Exchange 2007 will fail with ecRpcFormat (0x000004B6) if the output buffer is less than 0x00008007. Exchange 2013 and Exchange 2016 will succeed if output buffer is less than 0x00000008, but no request ROPs will have been processed.

<21> Section 3.1.4.2: Exchange 2007 does not fail if the request buffer value of the cbAuxIn parameter is larger than 0x00001008 bytes in size.

<22> Section 3.1.4.2: Exchange 2010 will fail with ecRpcFailed (0x80040115) if the value of the cbAuxIn parameter is greater than 0x00000000 and less than 0x00000008.

<23> Section 3.1.4.2: Exchange 2003, Exchange 2007, Exchange 2013, and Exchange 2016 support returning data in the rgbAuxOut parameter.

<24> Section 3.1.4.2.2.1: Exchange 2003, Exchange 2007, Exchange 2013, and Exchange 2016 support returning data in the rgbAuxOut parameter.

<25> Section 3.1.4.4: Exchange 2010, Exchange 2013, and Exchange 2016 do not return the ecRejected error code.

<26> Section 3.1.4.5: Exchange 2003 and Exchange 2007 do support the EcRRegisterPushNotification method. The initial release version of Exchange 2010 and Exchange 2010 SP1 do not support the EcRRegisterPushNotification method and return ecNotSupported. Exchange 2010 SP2 supports the EcRRegisterPushNotification method when a registry key is created to support push notifications, as described in [MSFT-ConfigStaticUDPPort]. Microsoft Exchange Server 2010 Service Pack 3 (SP3), Exchange 2013, and Exchange 2016 do not support the EcRRegisterPushNotification method and return ecNotSupported.
