I have searched and found a few others with this problem and I could not find any solution that worked for me.
With Microsoft 365 personal can you access the calendar using the Outlook Android app? When I try to login to add my account I receive this error.
An error occurred during authentication. Please try again later.
Tried using the app to contact support, but just get a spinning blue circle saying contacting to support.
Tried clearing cache, deleting Outlook and reinstalling different WiFi and mobile data, changing password and I keep receiving the error.
I can login using other apps and with the browser. Outlook is the only problem.

I am asked to enter my user name and password. Also tried using Microsoft Authenticator.
Username and password work then a quick authentication in progress (or something close to that) then the "An error occurred during authentication. Please try again later." And back to the add account screen.
After many attempts, Got it working after trying the below steps with my custom domain office 365 account in Andriod 13.
(The mail fix seems, after clearing Outlook app data and cache, phone need to be restarted).
Settings -> Apps -> Outlook app -> Cleared data & cache. Force stop. => not working
Uninstalled and installed Outlook app ==> not working
Outlook app Cleared data & cache . And restarted the phone => Working!
Hi Kenny,
I am also having the same problem I am using my custom domain and it's working well on the web, but when I try to sign in to the Outlook mobile app, it gives the same error it gave to you.
you're the only survivor here, please assist how outlook.com started working with your custom domain email. and how the alias is created.
Thanks, Kenny
Hi Kenny! This is Raech. I'm an Outlook.com user like you and I'm happy to help.
To clarify, are you trying to add the account via the native Calendar app or through the Outlook mobile app itself?
Do you have a company portal app or Intune installed?
I will try that again. If not I guess I just cancel and move back to Google.
Thanks for trying to help.
