- Jeremy,
try to reinstall the agent. It will fix the issue.
Have to done any changes to MRS configuration file?Sankaperera thanks for the tip. My issue ended up being super simple and the on-prem object's ExchangeGuid needed to be set to match the EXO mailbox'. This problem used to get a nice and easy error message but now gets this new odd and unhelpful one. Nonetheless I was stung by my own weak blinders.
