We installed Office 2010 from our VS2010 MSDN Premium subscription but after the installation has occurred, Outlook 2010 tells that the administrator has blocked Outlook 2010 from connecting to the Exchange Server. I am wondering if there's a turnaround to make Outlook 2010 work?

My officemate installed the program first and his steps are the following:

Launch Office 2010 installation with existing Office 2007 installed. Selected upgrade, delete existing Office 2007 installations EXCEPT Outlook 2007 (programs installed are Word, Excel, Powerpoint and Outlook)Technically, Office 2007 runtime is still in his machine. After installation, he restarted the computer and Outlook 2010 worked.

In my case, I followed the same, Outlook 2010 was blocked from Exchange Server. I am not sure with the version of Exchange server but would there be any tweaks to address this?

You can't have two versions of Outlook installed side-by-side in the same OS session (you can have two on the same machine if one is in a VM). Outlook doesn't like it and unpredictable problems can result. Make sure to uninstall Outlook 2007 before (or while) installing Outlook 2010.

Can you ping your Exchange server by name from the affected workstation? How are you connecting to the Exchange server? (LAN? VPN? Outlook Anywhere?)

Thanks for the reply. The steps my officemate took was the one I mentioned to you. Supposedly, that WON'T UPGRADE Outlook 2007 and instead the rest of the suite programs but Outlook would still be 2007. What happened to my officemate's machine was the installation updated also Outlook that's why he was able to use Outlook 2010 using the same exchange server where my account is connected. I was wondering if there's a way, say to impersonate Outlook 2010 as Outlook 2007 to make it work in the exchange server.

Well, if you upgrade the whole suite, INCLUDING deleting Outlook 2007, it should upgrade your existing Outlook 2007 profile to Outlook 2010. Deleting the program doesn't delete your profile. Outlook 2010 should then connect to the Exchange server the way Outlook 2007 did.

Have you consulted with your Exchange admins to get their assistance on connecting your Outlook 2010 to the Exchange server?
