I configured Outlook to connect to Office 365. For some reasons, it could not connect Exchange online. I believe the local policy blocks the connection. I want to take a look the Outlook policy but I have no clue.

I have installed all updates, cleared credential, installed Desktop Setup and created a new profile.

Please assist me in this issue.

If you think it might be a local policy (that is a policy set on the PC and NOT received from the network/domain Group Policy), then you can logon to the PC as an admin of the PC and run GPEDIT.MSC to view the local policies.

Why do you believe that the local policy blocks the connection?  How are you making this determination?

Use the connectivity tool:  http://technet.microsoft.com/library/feba32b0-b7eb-4b1b-ba3d-99e20ba82a8c

Do you have, or previously had local Exchange? Is so, Outlook is most likely is hitting the SCP and trying to connect to it first. You can work around this by modifying the registry keys:


If this doesnt help, check your firewall/proxy, AV. Make sure you have allowed the IPs listed here:


Make a screenshot from the connections dialog in Outlook (hold the CTRL key and right-click on Outlook's icon in the tray, select Connection Status), it will show you the servers it is trying to connect to and the status of the connection.
Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

I checked local policy again but nothing found. I check the AD Group Policy and found that OU was linked to some NIST policy. However, I don't know which one block the connection to Office 365. I am thinking about Office 2010 policy.

I have migrated over 200 mailboxes successfully. only this group has strict policies. What option do I select if I use the connectivity tool?

after I discussed with my manager, I removed all NIST settings. I am able to configure Outlook connecting to Office 365 now.
Thank you all for your ideas.
