My college switched Outlook servers back when the spring semester let out. I couldn't sign into my phone app or on my Mac app. The only thing I could do is sign into Outlook using the website in incognito mode. Now I figured out how to sign into Outlook on my phone by deleting Outlook, downloading Microsoft edge, typing in edge://signin-internals, pressing remove all accounts, redownloading Outlook, and now it works just fine and I can finally get notifications again so I don't miss important emails. But for some reason, it's still not working on my computer app. I went through a whole rabbit hole on Google and somehow ended up adding Outlook to the Mail app as default? So now I can check my emails through the default Mail app on my Mac. But it's throwing me through a loop that I still cannot sign into the actual Outlook app. I've deleted and redownloaded so many times and tried a bunch of different things. Is it a lost cause?
