Community. I recently attempted to install CU1 and ran into an error. It was suggested I should have installed CU3 but I was holding off until SP1 based on the recommendation of an MS Exchange engineer. I attempted CU1 because it was supposed to correct some scan to email attachment problems. Regardless, I attempted CU1 and it failed. I downloaded and tried CU3 and now it's telling me this.
An unexpected error has occurred and a Watson dump is being generated: Could not find a part of the path 'C:\Windows\Temp\ExchangeSetup\bin\EnterpriseServiceEndpointsConfig.xml'.
I tried to go to the path of course and it was indeed not navigable.
Any suggestions would be appreciated as mail flow has stopped.
