We all know when Outlook is configured with Exchange Mode (MAPI/RPC and RPC over Https). When Outlook clients are on a low-speed network or intranet, Outlook connects to the server using RPC/TCP (that is, the usual MAPI mode), and when Outlook is on a high-speed network or extranet, it automatically uses rpc/ HTTPS (that is, outlookanywhere). The configuration in Outlook is as follows:
650) this.width=650; "title=" image "border=" 0 "alt=" image "src=" https://msdnshared.blob.core.windows.net/media/ tnblogsfs/prod.evol.blogs.technet.com/communityserver.blogs.components.weblogfiles/00/00/00/31/06/metablogapi/ 3264.image_thumb_10c98215.png "" 448 "height="/>
If we want to implement let Outlook client whether in intranet, low-speed network or extranet, High-speed networks are connected to the Exchange Server through Outlookanywhere mode (forcing Outlook clients to connect to the Exchange server by using Outlookanywhere mode to upgrade Exchange 2010 to 2013/ 2016 is beneficial), there are two ways to achieve this:
1. Receive changes to Outlook configuration, such as.
650) this.width=650; "title=" image "border=" 0 "alt=" image "src=" https://msdnshared.blob.core.windows.net/media/ tnblogsfs/prod.evol.blogs.technet.com/communityserver.blogs.components.weblogfiles/00/00/00/31/06/metablogapi/ 6835.image_thumb_40f35d89.png "" 441 "height="/>
2. This function can be achieved by modifying the outlookproviderflags option. The specific commands are as follows:
The following command is mandatory for Outlook to use Outlookanywhere mode to connect to Exchange:
Set-outlookprovider Expr-outlookproviderflags:serverexclusiveconnect
Set-outlookprovider Exch-outlookproviderflags:serverexclusiveconnect
Cancel set to:
Set-outlookprovider Expr-outlookproviderflags:none
Set-outlookprovider Exch-outlookproviderflags:none
Set up Outlook clients to connect to an Exchange 2010 server using HTTPS at low or high speed networks
