Project Scope

They recognise the power and potential of every single child. But this is often suppressed by poverty, violence, exclusion and discrimination. And it’s girls who are most affected. Their ‘Because I am a Girl’ campaign is a global movement that’s taking action to see a world that values girls, promotes their rights and ends injustice.
They encourage and help children take an active role in finding solutions to their problems and realising their rights and their full potential.

The Project.

Plan, a global charity, has utilised Exchange as its primary email platform.  A strategic decision was taken to implement Office 365 and, as the first phase, migrate to Exchange Online.  With a globally distributed workforce, a complex Active Directory and identity management infrastructure, and 12,000 mailboxes, this was one of the most complicated Office 365 implementations and migrations.
