A few of you emailed me when you noticed an error running ExFolders on Exchange 2010 SP1, which was recently released. Attempting to navigate into a mailbox would throw an error stating, “Error: Method not found.” This was due to some changes in the DLLs that ExFolders relies on.
We’ve just posted a new version of ExFolders that works properly with Sp1. You can find it here.
The RTM version is still available for download as well. Be aware that the RTM version won’t work on Sp1, and the Sp1 version won’t work on RTM, as far as navigating into mailboxes.
