Using classic Outlook for Windows in business environments
Thanks again David for your support on this very painful situation (you are the only one from Microsoft giving us answers, even on weekend, so we really appreciate it).
Unfortunately in my case, I don't have the option to upgrade my desktop and mobile Outlook clients, so the fact that OAuth has been activated without any previous notice in our Hotmail or Outlook.com accounts, this makes that I don't have any solution to solve this issue as I cannot use the New Outlook nor some updated Android clients.
Is it really not possible to disable temporally this OAuth feature in our impacted Microsoft accounts so we can resync temporally our accounts and have some time to prepare for some workaround?
If the OAuth activation is definitive in our Hotmail or Outlook.com accounts, then I will for sure have to move all my data to my Gmail accounts that still work correctly in my desktop and mobile clients.
