Mailbox is not syncing and the error below is noted:
Error System.Management.Automation.CmdletInvocationException: Windows PowerShell updated your execution policy successfully, but the setting is overridden by a policy defined at a more specific scope. Due to the override, your shell will retain its current effective execution policy of "Unrestricted".
In the section of the MaGE.log preceding this you may see a line similar to
Execute PowerShell: Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope process
Setting the local (or Group policy) to a remotesigned executionpolicy should resolve the described error and also allow the mailbox to proceed to Synchronize
