Step 3: Configure the Office 365 side

To configure a non-hybrid Office 365 for CMG’s F/B Connector in a single/shared namespace environment:

2
Configure an Autodiscover website for CMG that is not Autodiscover.x.y—since that name is reserved for Outlook use. (In these examples, the "x.y" domain is the SMTP address to the right of the @ symbol.) The CMG website could be, for example, coexist.x.y. The CMG website must also have a matching certificate. (To obtain and install a matching certificate, see 4.2: Obtain and install web services certificates.)
3
Run the O365 Add-AvailabilityAddressSpace cmdlet for the CMG Autodiscover address ("coexist.x.y") configured in step 2 above.
4
In DNS, make sure the coexist domain has an A record pointing to CMG.
5
Test the configuration: Open a web browser and enter the URL ("https://coexist.x.y/autodiscover/autodiscover.xml") to verify that it resolves it correctly and without any certification errors.

CMG’s Free/Busy Connector can facilitate the flow of free/busy information among multiple subdomains supported by both Office 365 and the GroupWise servers. To support this scenario, run the Add-AvailabilityAddress­Space cmdlet on Office 365 for each GroupWise SMTP domain supported.

Step 4: Configure CMG's FBC Web Server

To configure CMG’s FBC Web Server:

4.1: Physically install the CMG FBC components

For any given scenario and configuration, it is possible to install all CMG F/B Connector components on a single server, as shown in the illustrations in the introductory chapter (Determine your FBC scenario) of this Guide. However, many production environments experience sufficient query volume to warrant separate servers to ensure optimal performance. The installation instructions here therefore describe how to install CMG’s F/B Connector on two servers.

See the configuration map you made in step 1 above to determine which components should be installed to which servers for this scenario.

If you prefer that all subcomponents reside on a single server, simply combine the components of CMG Server 1 and CMG Server 2 as they are listed in step 1 above. All CMG Free/Busy Connector subcomponents are installed by the AutoRun utility included in the CMG product kit.

IMPORTANT: Before you install, on any computer that will host any CMG FBC web subcomponent, remove the IIS DefaultWebSite: In the navigation tree at left, right-click DefaultWebSite, and then select Remove from the pop-up menu. CMG requires a dedicated server for its own web subcomponents.

Use the AutoRun utility now to install all the necessary CMG F/B Connector subcomponents on the computer(s) where you want them installed.

IMPORTANT: Remember, the CMG AutoRun installer must be run on the computer where you want to install a particular subcomponent. If you are deploying the F/B Connector to two different computers, you must run the AutoRun installer twice—once on each computer.

Remember: For Exchange queries for GroupWise F/B information, the simplest approach is to dedicate a separate CMG FBC Server 2 (as noted in step 1 above, for Exchange queries to GroupWise, and GroupWise replies) for each GroupWise server, with all the CMG servers feeding into the single Exchange server.

It is technically possible, but somewhat more complicated, to configure a single instance of the GroupWise FBC Service, EWS and Autodiscover to process free/busy traffic to and from multiple GroupWise servers—an approach that requires more elaborate GroupWise configurations.

4.2: Obtain and install web services certificates

CMG Web Server components must support HTTPS to accept SSL connections. The server on which these components are installed must have a certificate that Exchange trusts. The single certificate must cover the primary domain and all subdomains supported by the GroupWise Server. The certificate covers the Autodiscover and EWS web services.

CMG includes an Autodiscover Certificate Wizard to automate much of the process of installing this necessary certificate for the Free/Busy Connector. The wizard can be launched from CMG’s Management Console, on the Quest Web Services screen (under GroupWise Free/Busy Connector), as described in the procedure documented in the next subtopic below (see Using the Autodiscover Certificate Wizard to Obtain and Install a Certificate). Alternatively you can manually request and install a certificate, as described in the second subtopic below (see To Manually Request and Install a Certificate Using IIS 7.0–8.5).

Using the Autodiscover Certificate Wizard to Obtain and Install a Certificate

Even when using the wizard, you will still have to manually request the certificate, and then tell the wizard where the certificate file resides, so the wizard can install it for use with CMG.

To use the Autodiscover Certificate Wizard to install the necessary web services certificate using IIS 7.0–8.5:

1
In CMG’s Management Console, on the Quest Web Services screen (under GroupWise Free/Busy Connector): Click the Autodiscover Certificate Wizard button to launch the wizard.
To get a certificate from a public CA: Go to the web site of the public CA, and follow their instructions to request a certificate. At some point you will paste into the request form the text you copied from the wizard (in step 2 above).
a
From a web browser, enter https://<Local_Certification_Authority_computer>/certsrv
b
Click Request a certificate, then click Advanced certificate request.
c
Select Submit a certificate request by using a base-64-encoded CMC or PKCS #10 file, or submit a renewal request by using a base-64- encoded PKCS #7 file.
e
In the Certificate Template box, select Web Server.
f
Click Submit.
g
Select Base 64 Encoded, then select Download certificate.
4
Back in the Autodiscover Certificate Wizard: Click Next.
2
From the Actions Pane, select Create Certificate Request.
3
Enter autodiscover.<smtpdomain> or <smtpdomain> for the primary domain and all required subdomains. Then click Next.
To get a certificate from a public CA: Go to the web site of the public CA, and follow their instructions to request a certificate.
a
From a web browser, enter https://<Local_Certification_Authority_computer>/certsrv
b
Click Request a certificate, then click Advanced certificate request.
c
Select Submit a certificate request by using a base-64-encoded CMC or PKCS #10 file, or submit a renewal request by using a base-64- encoded PKCS #7 file.
e
Copy and paste the text from the certificate request into the Saved Request box when you selected Submit a certificate request by using a base-64-encoded CMC or PKCS #10 file, or submit a renewal request by using a base-64-encoded PKCS #7 file.
f
In the Certificate Template box, select Web Server.
g
Click Submit.
h
Select Base 64 Encoded, then select Download certificate.
2
From the Actions Pane, select Complete Certificate Request.
3
Select Add. Select https as the type for a secure site, and enter the IP address and port number.

This procedure lets you configure a single certificate to answer for multiple addresses. This is obviously necessary for a multi-/subdomain configuration, but also, for a single-namespace environment, to create a certificate that will cover both Autodiscover and the root domain.

First, you must enable the SAN (Subject Alternate Name) flag on your CA. On the machine running CA services, run these commands at the command prompt to enable the flag:

When the SAN flag is enabled, you can create the certificate:

1
Open IIS on the machine running F/B and select the server. Scroll to the bottom, open Server Certificates, and click on Create Certificate Request.
2
For the common name, enter something appropriate for your larger domain. For example, for a domain alejandro.xyzcorp.com, the common name on the certificate is *.xyzcorp.com. (This is somewhat generic, as we will later add specific namespaces to the certificate.)
5
Open the certificate web enrollment page for the CA of your domain— e.g., https://hostname/certsrv. Then select Request a Certificate, and then select Advanced Certificate Request.
6
Select Submit a certificate request by using a base-64-encoded CMC or PKCS #10 file, or submit a renewal request by using a base-64-encoded PKCS #7 file.
7
In the Base-64-encoded certificate request box, paste all of the text that you copied from the text file in step 4 above.
8
For the Certificate Template, select Web Server.
9
In the Additional Attributes box, enter any alternate-domain information in this format:
... with &dns=dns.name appended for each alternate domain you want the certificate to handle.
For a single-namespace environment: Enter the autodiscover and root domain, like this:
For a multi-/subdomain environment: You can enter as many domains as you like:
10
Select the DER encoded radio button, and then select Download certificate chain.
12
Go back to IIS and click Complete Certificate Request.
13
For the Filename containing the certification authority’s response, click the Browse button and select the certificate you just saved. (Be sure to change the file type to *.* instead of *.cer, or you won’t see the file you saved—since it is a .P7B extension.) Type a friendly name that is easy to remember and identify so you can find your certificate on the list later. You should then see your new certificate on the list.
15
Click the Details tab, and scroll down to Subject Alternative Name. Highlight this field, and you should see all of your domains in the Details box.

Now bind your certificate to the HTTPS protocol on the QuestFreeBusy website:

2
In the Actions pane on the right, select Bindings.
3
Select https and click Edit.
4
In the Edit Site Binding window, in the SSL certificate drop-down list: Select the certificate you just created.
