A common issue we see is clients getting an error stating “Cannot Synchronize Address Book”. It looks like in the image; there are several reasons clients could get this error. One possible reason is the TLS Certificate hasn’t been selected yet in IIS on your OCS 2007 Front End Server (in a Standard Edition Deployment) or on your Web Components Server (in an Enterprise Edition Deployment).
To see if this is the cause, do the following:
- Open the Internet Information Services (IIS) Manager from Administrative Tools.
- Expand the Computer and then Web Sites.
- Right click on Default Website and then click on Properties.
