Using Outlook for Android in business environments for email and scheduling
Similar problem. Outlook was crashing every time I tried to check my email today Dec 18, 2023 (on my Galaxy s22). I uninstalled it and tried to reinstall, restarted phone several time, changed password, and I can't get it to "authenticate" my account now.
I can still access on desktop, but the phone app seems to be on the fritz.
(I use Microsoft 356.)
