Re: Office 365 Migration from E3 to M - Dirsync implications?

Hi MustQ,

When disabling Dirsync, Office 365 system will take up to 24 hours to complete deactivation of the server. The duration depends on the number of objects that are in your Windows Azure AD tenant. That’s why I said disabling Dirsync could take up to 24 hours.

Thanks,
