"""
This script is an example of 'exchangelib' usage. It will give you email and appointment notifications from your
Exchange account on your Ubuntu desktop.
Usage: notifier.py [notify_interval]
You need to install the `libxml2-dev` `libxslt1-dev` packages for
'exchangelib' to work on Ubuntu.
Login and password is fetched from `~/.netrc`. Add an entry like this:
machine office365
login MY_INITIALS@example.com
password MY_PASSWORD
You can keep the notifier running by adding this to your shell startup script:
start-stop-daemon \
--pidfile ~/office365-notifier/notify.pid \
--make-pidfile --start --background \
--startas ~/office365-notifier/notify.sh
Where `~/office365-notifier/notify.sh` contains this:
cd "$( dirname "$0" )"
if [ ! -d "office365_env" ]; then
virtualenv -p python3 office365_env
fi
source office365_env/bin/activate
pip3 install sh exchangelib > /dev/null
sleep=${1:-600}
while true
do
python3 notifier.py $sleep
sleep $sleep
done
