Hi,

I tried the suggestions/pointers as outlined in the following link

https://gitlab.gnome.org/GNOME/evolution-ews/-/issues/58

But it still doesn't work for me.

Maybe my evolution and evolution-ews is too old?

Do I need to download the latest source code for evolution and 
evolution-ews and compile them myself?

Are there any good guides for me to follow?

Thank you.
