Outlook2010 connection to Microsoft Exchange is unavailable

Hi, I just setup Exchange and Outlook. My Win 7 and the server controller Win2008 (installed Exchange2010) can ping each other. but Outlook 2010 in the Win 7 show that "the connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action" when i want to start Outlook.
Anyone can give some idea ? Thank you.

Hope you have installed CAS and all Microsoft Exchange services are running on the BOX ?
Hope the Mailbox Database is mounted ?
Are you able to access users mailbox using OWA\Webmail ?
Is the issue when doing a checkname or after that ?
What is the version of Outlook as if Outlook 2003 without latest SP it will have issues.

Is outlook point to the correct DNS server ?

Does owa work ? if so, can you send/ receive from owa ?

My best bet is that this is an issue with your CAS Server.

So, yes check if CAS Role is installed running Get-ExchangeServer | FL

Also, as Sulaimanw noted - check with webmail, this would bring about new line of troubleshooting where in we'll focus on client side issue versus server side issue.

Note, also which box is your OL pointing to for contacting Exchange?

My point exactly - that is why asked to run Get-ExchangeServer

Hope the Mailbox Database is mounted ?
Are you able to access users mailbox using OWA\Webmail ?
For this reason, webmail was being asked to login and check - if not, we're looking towards server side issues, viz a viz mailbox / database / server issues.

Is the issue when doing a checkname or after that ?
Profile is configured and it is an issue with OL starting up.

when you ping are you pinging the ip or the internal server name..
typically this happens if your dns is set to your internet router rather than the ad server.
also - confirm all the exchange services are running on the server and there are no errors.
check outlook web access and/or check it directly on the server.

Thank all of you for your help. and I am sorry for the delay.
I have not installed CAS, and OWA do not work. When i used owa to reach the exchange, i got the error message:

403 - Forbidden: Access is denied.
You do not have permission to view this directory or page using the credentials that you supplied.

I can reach the server(installed the exchange) by typing" \\[server name]" in RUN. When i set up mail in client PC and added a account in Add New Account, i always got "the action cannot be completed, The name cannot be matched to a name in the address list" actually i already added the user account in the server. Now i cannot connect the Exchange with my  PC

You need to have CAS installed if you are using Exchange 2010 Mailbox to access their Mailbox data.
CAS is the role that allows your Client connection to their Mailbox.

Thank you so much. I always checked the connection problem because i followed the protocol which never mentioned CAS. it's weird

Manpreet SIngh KhatraConnect With a Mentor Solutions Architect, Project LeadCommented:
With E2k10 all Client connections (Outlook, OWA, Mobile, etc) will happen through CAS.
Thats the reason its the first if you choose the default installation process.

CAS is very important, but it takes a lot time to do it. If i only have one Windows 2008 server with one Exchange 2010 installed in it, do you think i still have to install CAS ? Do I have other options for client to connect the server with Outlook 2010 ?

I have not installed CAS, and OWA do not work. When i used owa to reach the exchange, i got the error message:

If you have one Exchange box, chances are you have installed CAS on it, which is WHY on my first post I requested you to provide an output to a cmdlet which would give us insight to the roles installed on your box. Unfortunately, we've been talking to and fro but we aren't making progress cause you're not providing details to us. Understand that we are here to help you provided you're helping us with answers, else we'll be chit-chatting and you're precious issue won't get solved.

I didn’t find the protocol which is for my situation ( I only have one server for everything ). So I did it according to the link:

http://howtoexchange.wordpress.com/2009/12/16/configuring-client-access-array-for-exchange-2010-walkthrough/

I set Exchange 2010 server and CAS at the domain controller. From the client PC, I can ping CAS array ip address and the server ip address, but when I set up a client account in client PC, I always got error message : “ the name cannot be solved. The connection to Microsoft Exchange is unavailable. …”  or "the action cannot be complete, the connection to Microsoft Exchange is unavailable ..."

And when I created client access server array, I typed “Get-ClientAccessArray”, and “New-ClientAccessArray -Fqdn "servername.domainname.org" -Site "Default-First-Site-Name" “  Both of them did not work. Below is its message:

------------------------------------

I only have one server. Do I have to use TWO servers with CAS for Outlook 2010 to reach the Exchange 2010? Thank you !

Fair enough WIN08W is your CAS box, now when you work with OL, can you configure it using WIN08W? If not, can you ping the box? if not, can you ping the box with WIN08W FQDN? If not, can you telnet WIN08W on ports 80 / 443 / 135?

davidy2001Author Commented:
I can ping WIN08W, but I cannot ping its FQDN. I changed my PC's DNS pointed at the server DNS. and then it works !

But question is that i tried many user accounts which are registered in ADUC of the server.
Only Administrator account can work, all other accounts cannot still work. Why ? I dont know it.
Thank you

What was the DNS earlier pointing to for a normal user? They should always point to your DNS Server NOT external. That is the problem.

is your pc a member of the domain? if dns was incorrect then possibly your machines arente domain members either?

davidy2001Author Commented:
that's one of questions i have. i thought it was a problem, but later i dont think so. my pc can not join the domain due to home version. but i can share the file which are located in the server.

now, suddenly, i lost connection of my outlook with the server. i want to change all ip address in all the devices. but i cannot find where to re-configure the CAS i configured before. Anyone can tell me about it ? Thank you.

Exchange_GeekCommented:
If you're PC cannot join the domain - in that case, you are not locally connected - you're connected over Internet using RPC over Https.

Which IP Address, you're thinking of changing?

Run a netstat -a and check which server are you talking over port 443

wolfcamelCommented:
if you are not a domain member then how are you trying the other usernames/ accounts - do you have local users with the same username and password as on the server?

Step one - upgrade from home to professional and join the domain. This will make things a lot easier.

IP addresses - shouldnt matter too much provided - the server is the DNS. Ideally you would have dhcp running on the server and not on the internet router.

If the server is showing under CAS it means CAS is installed ... however you can also run a command

Get-ExchangeServer "ServerName" |fl

I can tell you that CAS is installed as your command tells and the server shows when you click on CAS under Server config.

this information was already provided ages ago

Fair enough WIN08W is your CAS box, now when you work with OL, can you configure it using WIN08W? If not, can you ping the box? if not, can you ping the box with WIN08W FQDN? If not, can you telnet WIN08W on ports 80 / 443 / 135?

Run through each tab that you've listed under CAS, and check for internal URL - check if all of them point to your CAS - as in they start with https://CAS.domain.com/.......
