Service manager Exchange connector


After reading all the documentation of the exchange connector I  received the message “connector finished with error. “

After diving into the logs I found the following exchange connector Event Logs.

Solution 1

The solution was to make sure I could access as as the workflow user the the following url’s without a certificate error or other errors

This made disappear this error messages in the service manager log.
