Restrict which accounts can be used as Microsoft Edge primary accounts

Determines which accounts can be set as browser primary accounts in Microsoft Edge (the account that is chosen during the Sync opt-in flow).

If a user tries to configure a browser primary account with a username that doesn't match this pattern, they are blocked and will get the appropriate error message. You can configure this policy to match multiple accounts using a Perl style regular expression for the pattern. Note that pattern matches are case sensitive. For more information about the regular expression rules that are used, refer to https://go.microsoft.com/fwlink/p/?linkid=2133903.

If you don't configure this policy or leave it blank, users can set any account as a browser primary account in Microsoft Edge.
