Hello, I'm using office for mac 2011 on a macbook air running OSX El Capitan 10.11.2

For some reason, I'm being told that the security settings are not suitable to run my gmail account through it. I'm trying to remove my gmail account but when I go to preferences> accounts or tools> accounts I can't select the account to delete it and then outlook crashes.

I'd just like to delete the account as I'm mostly using hotmail for now and am tired of being asked for my gmail password every 5 seconds and outlook keeping crashing.

Can anyone help?
