Recently we received a trouble ticket from three customers with LOGbinder for Exchange. Two of them were large Enterprise customers. It turns out that if the version of .NET that is running on the Exchange Server, the server where LOGbinder for Exchange is installed and/or the server running the PowerShell scripts is different, the Exchange API is unable to function properly. It took some time to figure it out, but we’ve released a patch that will resolve the problem for the time being. It’s an odd problem to have, and seems to be a problem with .NET incompatibility between version 3.5 and 4.0.

We would be interested to know if you have noticed something similar in your environments where .NET 4.0 is running. Please let us know if you have experienced any .NET 4.0 incompatibility.
