[Evolution] Unsubscribe from folders on an Exchange server

[Tom <tom prost-net de>]

Hi there :-)

Little problem I have:
I access one of my accounts via EWS with Evolution.
(BTW: It's 3.36.3-0ubuntu1)
While the account has a lot of folders, that I personally do not need,
I unsubscribing from them everytime I see an error while connecting
them, but this does not seem to work as proposed. I still see them in
my user interface and EWS seems to still pull information from there.

Can I check (other way as the GUI), if unsubscribing has worked ?

Best,
Thomas
