3. You can verify that Outlook Anywhere has been enabled in Event Viewer. There should be an Event ID 3006 entry in the Application Log.
Test and troubleshoot Outlook Anywhere (optional)
It can be found at the following URL:
In case the URL ever changes, you could also look for "ExRCA" using your preferred search engine (Bing, Google, etc.).
One pre-requisite is the creation of a user account whose credentials can be used for the various tests. It is recommended to create such an account for testing purposes and then delete the account afterwards so the credentials cannot be reused or misused, presumably by someone who could conceivably access them one way or another.
On the ExRCA homepage, we can select from several tests: ActiveSync, Web Services, Outlook Anywhere, Autodiscover as well as Inbound and Outbound SMTP message flow.
In the context of my migration to Exchange Online, which requires Outlook Anywhere, I'll select the "Outlook Anywhere" test.
I enter the credentials of my test user:
The tool requires us to enter a "verification code" as well. The verification is valid for 30 minutes, after which another verification code must be entered:
I then click on "Perform Test" (in the lower right-hand corner).
The results are displayed...
And I have the option to "Start Over" or "Run Test Again".
The Outlook Anywhere test is successful in this case but let's create a situation where it would fail and then resolve the problem (this is, in fact, the problem I encountered when I performed the test for the first time).
In this scenario, we are running Exchange 2007 (SP3) on a Windows 2008 (SP2) server. By default, a component known as the RPCProxy attempts to connect, preferably with IPv6, to a component known as the DSProxy that... does not listen for IPv6 connections.
This produces the following error message:
- Type 0 to enable all IPv6 components. (Windows default setting)
- Type 0xffffffff to disable all IPv6 components except the IPv6 loopback interface. This value also configures Windows to prefer using IPv4 over IPv6 by changing entries in the prefix policy table.
- Type 0x20 to prefer IPv4 over IPv6 by changing entries in the prefix policy table.
- Type 0x10 to disable IPv6 on all nontunnel interfaces (both LAN and Point-to-Point Protocol [PPP] interfaces).
- Type 0x01 to disable IPv6 on all tunnel interfaces. These include Intra-Site Automatic Tunnel Addressing Protocol (ISATAP), 6to4, and Teredo.
- Type 0x11 to disable all IPv6 interfaces except for the IPv6 loopback interface.
