Accessing OWA from Multiple Domain URL

If we got a requirement for allowing access  multi domain users to access OWA from different URL’s

Below is steps how you can implement more than one OWA & ECP on one Exchange 2013 server

Lets assign new ip for new website

82

Lets Copy the OWA & ECP folder from

OWA

C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\OWA 

 to

C:\Program Files\Microsoft\Exchange Server\V15_Arabitpro\ClientAccess\OWA

 

ECP

C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\ECP

to

C:\Program Files\Microsoft\Exchange Server\V15_Arabitpro\ClientAccess\ECP

85

Create new website from IIS  “Webmail

84

86

Give the Default path to “C:\Inetpub\wwwroot”  folder

Bind this with the following IP which we have assigned to 80 port as well 443

Now we are ready with the new site “webmail”

Under IIS Settings

ISAPI and CGI Restrictions

87

We need to  ALLOW the following  DLL file

C:\Program Files\Microsoft\Exchange Server\V15_Arabitpro\ClientAccess\Owa\auth\owaauth.dll

Create OWA & ECP Directory by using the following CMD using EMS

88

New-OwaVirtualDirectory -website “Webmail” -Path “C:\Program Files\Microsoft\Exchange Server\V15_Arabitpro\ClientAccess\Owa”

The warning indicates we need to create ECP Virtual Directory also in the same website

For ECP use the following

 

 

New-EcpVirtualDirectory -website “Webmail” -Path “C:\Program Files\Microsoft\Exchange Server\V15_Arabitpro\ClientAccess\ECP

 

You need to install Certificate for External Users with the new domain name

 

Login to EAC

Under Servers –> Virtual Directories –> select the webmail OWA and ECP check the authentication and set the new domain URL

 

90

Reset the IIS

93

 

Now you need to create accepted domain and Email policy for new domain

Under Mailflow –> Accepted Domains

94

91

here im https://mail.arabitpro.com/owa

92

Https://ex-15.test.com/owa

You are done with it.

Now we have users from different emails address accessing there mails from there own domain url’s

95

96

I hope the above information helpful for you thanks for viewing.

  1. Hello, Thanks to share with us your knowledge, I have one question, in you example your server seems to hold Mailbox and CAS roles. What if I have two CAS servers and two DAG servers, this path does not exist in CAS server should I use the path where the default owa points to in my CAS servers?
