I deployed exchange 2010 on sbs 2011 over the week-end. I figured it was pretty much good to go until I tested it this morning.

Autodiscover is failing miserably.

I did a bit of checking online into what I need for autodiscover records for sbs 2011 / exchange 2010. I am still a little unclear. I don't do exchange setups very often and so I end up having to relearn and fumble around a bit in the process.

I have an mx record of mail.domain.com forwarding to the sbs server's IP address. Is this what I want?

What do I need for an autodiscover entry in dns?

Do I need to remove any other DNS records?

Follow the steps mentioned in the link

http://www.thirdtier.net/2011/06/setting-up-autodiscover-for-sbs-2011/

1) You'll need to set up DNS to point to _autodiscover._tcp.domain.com internally and externally
2) You'll need cert to setup for mail.domain.com / autodiscover.domain.com / server FQDN / Server NETBIOS Name
3) Either a self-signed or purchased UCC Cert is required.
4) You'll need to enable the cert on the following links.

AutodiscoverServiceInternalUri
Get-WebServicesVirtualDirectory
Set-OWAVirtualDirectory
Get-OABVirtualDirectory
Get-ActiveSyncVirtualDirectory
Set-OutlookAnywhere

That should be it.

I have added:

A Record

Host                     Points To                          TTL

Autodiscover        XX.XXX.XX.XXX                  1/2 hour


Is it better to have mail.domain.com as an mx record or as an a record.

A record wouldn't help - you'll need SRV Records for it.

more over MX Record is for mail flow and not for autodiscover, you'll need to talk with your External DNS Vendor to provide you a SRV record for _Autodiscover._tcp.domain.com

Here are the steps for creating SRV Records

Open the DNS Management MMC snap-in.
Expand Forward Lookup Zones.
Locate and right-click the DNS zone, and then click Other New Records.
Click Service Location (SRV).
Service: _autodiscover
Protocol: _tcp
Port Number: 443
Host: mail.domain.com
Click OK.

Exchange_Geek

P.S - mail.domain.com should be changed to your webmail address, for example if your webmail address externally/internally is set to https://webmail.skype-lost.com/owa

then the above host should point to webmail.skype-lost.com

The instructions you've given are for internal SRV creation.

What should my DNS entries be at Godaddy? What all should I have pointing towards this sbs?

Externally also your DNS Entries for the following should be pointing for towards your

A Record for mail.domain.com pointing towards SBS
SRV Record for autodiscover.domain.com pointing towards SBS

MX is related to mail flow not OL Connections, MX is required for mail-flow and yes it is required to be pointed to your SBS to receive emails.

should the autodiscover srv entry at godaddy point to my sbs ip address or to mail.domain.com?

I have it setup as name: autodiscover,domain.com and target:(ip address), but it seems to want to use a domain name as the target...

SRV record is required for autodiscover to point to mail.domain.com
A Record for mail.domain.com needs to be pointed to SBS Server.

At GoDaddy:

I have this A record:

Host        Points to                

mail         XX.XXX.XX.XXX

I have this MX Entry:

Priority         Host              Points to

0                    mail              mail.domain.com

I have this SRV Entry

Service              Protocol       Name      Priority          Weight           Port          Target

_autodiscover   _tcp              @             0                     0                    443            mail.domain.com



Does this look right?

Looks good to me. Also, have a PTR Record for mail-flow - this is normally a check to understand if the sending IP belongs to the sending Organization or not. Just in order to block spoofing.
