The title of this blog entry is a little bit of a misnomer. I say that because the underlying issue also caused another issue that I will mention in this post so that others who are experiencing these can get this resolved. Let me tell you, this has been an epic headache for a few months now, so to be able to finally have them resolved is a huge relief!<\/p>\n

Like I said, the underlying issue caused another problem. The first problem we noticed is that when we tried to use Autodiscover to create user profiles in Outlook 2007 outside of the network it would fail. For our users to use RPC over HTTPS aka Outlook Anywhere, we had to create their Outlook profile while connected to the network. After that they could use Outlook Anywhere.<\/p>\n

The second problem we noticed is that users outside of the network couldn\u2019t expand distribution groups. They could access the Global Address List, but when they tried to expand distribution groups over Outlook Anywhere they would get the following error:<\/p>\n

\n

Cannot perform the requested operation. The command selected is not valid for this recipient. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action.<\/strong><\/span><\/p>\n

\"Cannot<\/a> <\/span><\/p>\n<\/blockquote>\n

I finally found the answer on Aaron Mark\u2019s blog<\/a> talking about an Outlook Anywhere bug with Exchange 2007 and Windows Server 2008. The problem lies in IPV6. On our network adapter we have IPV6 unchecked as we weren\u2019t using it, but it turns out that is not good enough.<\/p>\n

If you are experiencing something similar, you may also notice that when you hold control, click on the Outlook icon in the system tray and select Connection Status<\/strong> you will see a good connection to MAIL<\/strong> but your connection to DIRECTORY <\/strong>will either say CONNECTING<\/strong> or DISCONNECTED<\/strong>.<\/p>\n

In order to fully disable IPV6 you have to do the following on your Exchange server along with unchecking IPV6 on your adapter settings. NOTE- MAKE SURE YOU MAKE A BACKUP OF YOUR REGISTRY BEFORE PROCEDING<\/span><\/strong>:<\/p>\n
