Office 365 – Active Directory Preparation Part 1
This lesson will be short and it is not for test, small or mid organization. As you can see that Office 365 is really big environment but it has some limitation.
Today limitation is object number. Default object limit for Office 365 and Microsoft Azure Active Directory is 50.000 objects (mail-enabled contacts, users, groups)
This is the limitation of first tenancy. However, the good news is that when you verify your first domain, this number increases to 300.000 objects.
If you have more than 300.000 objects in your system then you need to raise a ticket to Azure Active Directory Support team. They can increase the number for you.
If you have less than 50.000 objects in your system, you can sync your objects with SQL Express edition. If it is more than 50.000, you definitely need Full SQL 2008 standard edition.
