Hello ,

We are creating calendar appointment using workflow "create exchange item" activity within workflow.

Currently I have workflow designer with version 10.4.3.139 and when we try to configure exchange connection and clicked on "Test URL" its shows below error.

This request operation sent to net.tcp://localhost:8085/ManagementService did not receive a reply within the configured timeout (00:00:30). 
 The time allotted to this operation may have been a portion of a longer timeout. 
 This may be because the service is still processing the operation or because the service was unable to send a reply message. 
 Please consider increasing the operation timeout (by casting the channel/proxy to IContextChannel and setting the OperationTimeout property) 
and ensure that the service is able to connect to the client.

Also in workflow designer its shows this error "Create Exchange ItemUnable to connect to Exchange® service: 'The Autodiscover service couldn't be located.'."

We have another machine with workflow version 10.2  , everything's works fine. 

Kindly do let me know what is the problem.

Thanks,

Pratik Barot
