I have downloaded and installed the final version of Edge.
Upon first run and setup of account Sync is not available. And I'm not able to delete the Profile.
I have added a new profile in the browser using the same corporate Office 365 account. For that second profile sync is working fine.
Even after setting up multiple profiles I'm still not able to delete the initial profile and get rid of it from the profiles management.
I have solved the issue by deleting the Default folder in "%localappdata%\Microsoft\Edge\User Data"
We have seen the same issue for multiple user in the organization.
