outlook will not connect to exchange server

Posted on 2012-03-22
Last Modified: 2012-03-26
when I try to setup outlook 2007 on my win7 64 bit machine I receive an error message,

outlook cannot log on. Verify you are connected to the network and are using the proper server and mailbox name. The connection to microsoft exchange is unavailable. outlook must be online or connected to complete this action.

The dns setting are correct, gateway is correct server name is correct and mailbox name is correct. the ip address we are using is a static ip. I have googled this issue and found no solutions yet.

Is this affecting all users and all machines?  If you add another user from exchange is it still an issue?  Can you login as another user and try?

we have un/reinstalled outlook and we are still having the issues, the icon was never missing, and far as I know its affecting 2 users and 2 machines. I have tried to setup outlook thru my profile and i receive the error message as well.

Check the DNS settings on the Exchange Server.

Your server's DNS should point to the local server and the DNS on your server should be set to the local IP address of the server on the NIC settings.

If you are unsure, use and you should also ensure your DNS server is correctly configured on the network.

Can you ping the mailserver using the FQDN?

1. Check the network mask is the same as the network on the IP address configuration.
2. From Command-line, type: ipconfig / flushdns
3. Reinstall TCP/IP

I think, Please check the RPC encryption setting in user profile.

1.      In Control Panel, open the Mail item.
2.      Click Show Profiles.
3.      Select your profile, and then click Properties.
4.      Click E-mail Accounts.
5.      Select the Microsoft Exchange Server account, and then click Change.
6.      In the dialog box that contains your mailbox server and user name, click More Settings.
7.      In the Microsoft Exchange dialog box, click the Security tab.
8.      Click to select the Encrypt data between Microsoft Office Outlook and Microsoft Exchange check box, and then click OK.

This setting should be enable (or clicked) for communication between exchange 2010 and outlook 2007.

I don't believe reinstalling office will make a difference.

Please give us the IPConfig from the server and the PC to see the configuration
