        Hi,
it looks like you connect to the Hotmail account using evolution-ews.
It also seems like something caused your local address book copy out of
date. If right-click the book and picking Refresh won't help (I do not
know whether it's available in 3.28.x you have), then remove the local
cache in ~/.cache/evolution/addressbook/<ews-book-uid>/ (you can remove
all of them if unsure), which will re-download the book from scratch
the next time you start evolution-addressbook-factory and open the
address book. Ideally remove the files in ~/.cache when all evolution
processes (ps ax | grep evolution) are not running, though it's not
always possible (due to for example GNOME Shell keeps running the
evolution-calendar-factory), then restart the machine.
        Bye,
        Milan
