We like like to start using OMA. We have Exchange 2k3 (sp1) running on a  
  
Win2k3 (sp1). When we use any mobile device, we receive the same error:  
  
"Unable to connect to your mailbox on server MY-SERVER. Please try again  
  
later. If the problem persists contact your administrator."  
  
Any suggestions?

And we are trying to use Treo 650's.

Is the user's email username@companyname.com or do they have a  
  
different email address?

Hi,  
  
I get the same error message when connecting to OMA.  
  
Front End Server:     Exchange 2003 SP1 on Windows Server 2003 SP1  
  
Back End Server:     Exchange 2003 SP1 on Windows 2000 SP4 Adv. Server -  
  
Clustered  
  
The strange thing is, that only a few users get that error message. I tried  
  
to connect via mobile phone (Sony Ericsson T610) and via Internet  
  
Explorer...  
  
Thanks for any answers,  
  
MC

strange thing....  
  
Connecting to OMA with a newly created user works fine.  
  
If I create an user account by copying an existing user OMA fails to  
  
connect.

The user' primary SMTP address is firstname.lastname@company.com  
  
Every user has a SMTP proxy address: username@company.local  
  
The name of the Active Directory Namespace is company.local
