Just checked one of our servers and mas 5.0.218.0 supports up to 2010 SP3
this is from online help
This feature enables the UCA administrator to configure either a Google Server or an Exchange Server from which the UCA clients can fetch calendar availability information and update their Dynamic Statuses.
Exchange Integration supports Exchange 2007, Exchange 2007 SP1, Exchange 2010, Exchange 2010 SP1, Exchange 2010 SP2, Exchange 2010 SP3.
From the Calendar Type pull-down menu, select either Google or MS Exchange.
If you want to enable calendar integration, click the checkbox.
If MS Exchange is selected (if Google is selected go to step 4):
1.Enter the URL of your Exchange Server. The URL corresponds to Exchange Web Services (EWS). The exact URL depends on how your exchange server is configured, but is usually in the format
2.The version of the Exchange server is entered automatically when you successfully test the connection. The possible values are Exchange 2007, Exchange 2007 SP1, Exchange 2010, Exchange 2010 SP1, Exchange 2010 SP2, or Exchange 2010 SP3.
NOTE: When connecting to a 2010 SP3 exchange server, the version may still be shown as SP2 on the UCA server-manager.
3.Enter the username and password that you use to log into the Exchange Server. This user does not necessarily have to have administrative privileges on the Exchange server. Any user who can view other users' calendar availability information will suffice. If you are unsure what to enter here, contact your Exchange server administrator.
a.If you want to use impersonation, click the checkbox. If impersonation is enabled, then UCA client users will not have to provide their exchange password to use Calendar Integration. However, they still have to provide their Exchange username and primary e-mail address
b.Enabling impersonation can have security implications and requires administrative privileges on the Exchange server.
c.Refer to the following Microsoft websites for more details:
Exchange 2007:
Exchange 2010:
4.You can access the Advanced Calendar Integration Settings. The default values for these settings works appropriately under most circumstances so normally, these do not need to be adjusted. Change them only if you have very particular needs, such as high network latency. Be aware that changing these values affects calendar integration across ALL enterprises.
5.Test your connection to ensure that UCA can connect to either the Google Server or Exchange Server and communicate with it properly. If after clicking on the Test Connection button you receive an error stating "Invalid calendar server credentials", you need to troubleshoot the issue.
6.Click Apply to save the changes or Reset to clear the changes.
