moved a user mailbox from exchange 2003 to exchange 2010 sp1. &nbsp;The status completed.

Microsoft 365 Enterprise E5 is the most feature-rich version of Microsoft 365 and consists of Office 365, Windows 10, and Enterprise Mobility + Security (EMS). It provides the collaboration, productivity, automation, and security features an enterprise customer may need to support its digital business transformation initiatives in a single stock keeping unit (SKU),
which streamlines its deployment and utilization. For companies that do not need the full feature set, Microsoft offers different versions, such as the E3 SKU at a lower price point and F1 for firstline workers.
