Exchange Collector validation error: "Unable to Parse ExchangeVersion" when saving configuration

SYMPTOMS

When creating a new matter and configuring the "Exchange Collector" you may receive a pop-up titled "Validation Error" that says "Unable to Parse ExchangeVersion" when you try to save the configuration. This happens even after you change the ZyLAB.EDiscovery.Collectors.Exchange.dll.xml configuration file and after creating a new matter.

CAUSE

The configuration file (ZyLAB.EDiscovery.Collectors.Exchange.dll.xml ) has invalid value or already has a corrected value but the changes are not picked up yet.

RESOLUTION

The only valid values for ExchangeVersion are shown in the comment:
<!--Exchange2007_SP1, Exchange2010, Exchange2010_SP1 -->

If you try to use a value not on that list you will get the pop-up titled Validation Error that says "Unable to Parse ExchangeVersion".

The configuration file needs to be changed to a valid value:

Invalid:
        <!--Exchange2007_SP1, Exchange2010, Exchange2010_SP1 -->
        <ExchangeVersion>Exchange2007_SP3</ExchangeVersion>

Valid:
        <!--Exchange2007_SP1, Exchange2010, Exchange2010_SP1 -->
        <ExchangeVersion>Exchange2007_SP1</ExchangeVersion>

In the above examples, Exchange2007_SP3 is not a valid option and will therefor not parse the Microsoft Exchange version in use.

NOTES: 

• You must perform an IISRESET (or start and stop the ediscovery service application pool) to get the change to take effect.
• Be sure to perform the IISRESET after changing this configuration file.
