I set up a new account to replace my main EWS account and set it as default. I turned off “send and receive” email for the old EWS account when I realised searches were returning results from it. Then I noticed that I was seeing duplicates of the calendar entries, so I turned off “Exchange Web Services” on the EWS account, clicked Apply and it crashed, taking down all its running processes.
It may be significant, but I had already had an “eM Client has stopped responding” message, as I have reported here: Profile dialogue pops up at random
Have you tried removing your EWS account completely? If you haven’t try that.
Also do you have the latest Beta v11.0.196 ?
I am on 11.0.196.
I was reluctant to remove the EWS account altogether until I was confident about the beta (and, yes, I do realise that is the point of a beta). But I guess I have nothing to lose.
It should re-add your account with Graph and work fine if your server supports that already.
From reading the forum threads, eM Client are also updating / tweaking Graph implementation in a later Beta to request a more limited scope to hopefully reduce the need for admin consent if you have a strict server as @Olivia_Rust advised in here post below.
Removed the EWS account, let’s see what happens
