Did you ever receive a solution to this error? I am having the same problem. Thanks

I had this as well.

Upon further investigation, I found that the user’s OOO agent was enabled, but there were no dates in the OOO setup (Don’t know how this could happen though). Once I disabled the agent, added the dates, and re-enabled, everything returned to normal.

Hope this helps!
