This looks like the rest call is failing, possibly with a 500 server error. Is this new behavior and is it ongoing? Does the issue repro for all messages or only certain messages?

It has been going on for a while, I can't say exactly when it started. We use an on premise exchange server. Do REST calls work for on premise?

I can hard code this error to fall back to ews. Might be able to fix it tonight.
