Hi,

I have setup an exchange 2013 network. The goal is an hosted exchange sollution.

2x Clientaccess server (DMZ)
2x Mailstore server (LAN)
2x Domain Controller (LAN)

Webmail is working, activesync is working, but i can't connect with Outlook 2010. I have setup a proxy server of course in the profile.

When i have setup up the proxyserver and the servername (he-clientacc01) and click "check names" there is a prompt for username and password. An error apears "The connection to the Microsoft Exchange Server is unavailable. Outlook must be online or connected to complete this action".

I check the iis log of the clientaccess server where i connect to and is see this:

192.168.55.10 is the ip adress of the clientacc01
Why apears the 404 errors ? Is this the problem why i cannot connect in outlook ? and how can i resolve it ?

Thanx

Does Autodiscover work? You shouldn't need to configure the client manually.
Does Outlook connect internally correctly? Again that should work without prompts as Outlook Anywhere is the only connection method in Exchange 2013.

404s would usually mean you haven't got the virtual directory in place correctly, or there is some other problem with the web server configuration.

No, I have not configured autodiscover.

I have now noticed that I can connect manually when i use for the servername the ExchangeGUID of the mailbox followed by the UPN suffix.

When I want to configure autodiscover. Do I need a certificate for each domain ?
We have a lots of domains because it is an hosted environment.
I now we can use a wildcard, but the differt domains grows...

If i want do want to use autodiscover for all our customers, do I need a certificate for each domain ?

You cannot use Exchange without Autodiscover. It is not an optional feature.
Therefore you will need to configure something for Autodiscover.
An SSL certificate is required somewhere - again you cannot use Exchange without it.

You basically have three options.
1. Autodiscover.example.com in the SSL certificate. For lots of domains that is probably inpractical.
2. Autodiscover SRV records. http://semb.ee/srv
3. Autodiscover HTTP redirect.
