I have installed Little Snitch on my mac and From what my Desktop Support Tech told me yesterday, the constant connections to work that are locking out my password are being made to adfs.where.XXXXXX.net. Previously I had installed the complete 365 suite with outlook. For this install I did last night, I only installed the latest version of Outlook and I'm monitoring the outgoing requests made by outlook and it seems that the only call to adfs was when It did the authentication last night.
I'm going to keep tracking this to see if my mac attempts to call home.
Are there any add-ons that are installed with Outlook that might be trying to call home as well?
