How to Simplify Hybrid Office 365 Management

Unfortunately, the standard tools from Microsoft make it very complex to manage hybrid Office 365.

Daily operations involve multiple tools and scripting, e.g.:

  • AD Users & Computers to manage on-premises identities.
  • On-premises Exchange to manage on-premises email configuration.
  • Exchange Online Admin Center to manage Office 365 mailboxes.
  • Microsoft Admin Center to manage Office 365 users, licenses, and shared mailbox sent-to-items configuration.
  • Azure Portal to view and manage detailed Office 365 user properties.
  • Exchange Online PowerShell to configure calendar permissions, auto-reply scheduling, and Outlook auto-mapping.
  • Azure AD Connect PowerShell to trigger AD to Office 365 synchronizations.

This is very confusing, requires a lot of training of first-line supporters, and often results in senior-level admins getting involved in what should be day-to-day user support.

Additionally, you carry the cost and risk of running Exchange on-premises.

You can make all of these problems go away in two minutes.

With Easy365Manager, all daily management can be done directly from AD Users & Computers.

Easy365Manager adds two new tabs to user properties, giving you complete control of all standard  Office 365 mailbox settings, licenses, email addresses, etc.

You no longer need to log in to multiple consoles, and you don’t need to worry about attribute authority. Instead, all configurations take place in one well-known console.

Since AD Users & Computers has been around for more than two decades, any first-line supporter knows this and will master the new features with basically zero training.

With Easy365Manager, hybrid Office 365 becomes easy. Even when dealing with calendar permissions, which otherwise can only be managed via complex PowerShell scripting:

And it gets even better:

Easy365Manager is available as a 30-day trial which you can install and configure in less than two minutes.

Easy365Manager is a simple extension to the AD Users & Computers tool, and it introduces no changes to your schema or infrastructure.

Easy365Manager installs to any system running AD Users & Computers – even Windows 10.

Easy365Manager has no custom security layer, works with your Azure AD Connect, and runs parallel with (or without) your on-premises Exchange Server.

The (easy) changes you make using Easy365Manager result in the same configuration as when using the standard tools from Microsoft.
