Hi,

This issue may be caused by BinSearchFolders path setting incorrectly. Please take the following steps to solve this issue.

1. Open IIS >> Exchange BackEnd website >> ECP virtual directory >> In the Middle Pane >> Application Settings >> BinSearchFolders
2. Change the path with C:\Program Files\Microsoft\Exchange Server\V15\bin;C:\Program Files\Microsoft\Exchange Server\V15\bin\CmdletExtensionAgents;C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\Owa\bin
3. Then reset IIS to check this issue.

Best Regards.

You are exactly right. Thank you for the help. My 2013 Exchange server had this issue after the latest cu8 security update.
THANK YOU!
