If you use Win10 to download the new version of Edge browser, landing account found that can not login, may be the computer did not set Microsoft account.
My operation is:
Open the old version of Edge browser – Settings – Account and click on it. It will jump to the system’s Add Account interface and enter your Microsoft account to log in.
Then I looked at the old version of Edge and found that it had already logged in and synced automatically.
At this point, open the new version of Edge browser and click Login. Select Microsoft Account. A pop-up interface will automatically fill in the account you just logged in.
Point next step, enter password again, discover won’t report wrong, can land normally.
Conclusion: This error may be caused by the failure to check the local Microsoft account and the failure to automatically complete the account.
