How To Set Up A Hybrid Exchange Office 365 Environment –

Microsoft Exchange is a powerful email server and calendar widely used by small businesses, medium and large organizations in all folds. Most organizations run a local Exchange Server version that requires server configuration and management in their office location. Locals and organizations are constantly moving toward cloud-based Office 365.

Office 365 is a secure and extensible Exchange Online solution that frees organizations from configuring or managing their server hardware on the site.

Organizations may also opt for the Exchange hybrid deployment, which combines local Exchange with Office 365 – which provides a feature-rich user experience by offering the best of both worlds. In hybrid deployments, organizations can store data on their internal server hardware while reaping the benefits of Office 365.

The hybrid deployment also serves as an intermediate stage for transferring a local Exchange organization to Microsoft 365 or Office 365.

In this article, we’ll explain how you can set up an Exchange Office 365 hybrid environment and move mailboxes from your on-premises Exchange server to Office 365 or Exchange Online.

Next, you need to set up the coexistence between Local Exchange and Exchange Online using the Hybrid Configuration Wizard and then move the mailboxes.

The steps are as follows,

However, this is a time consuming process and may take several hours to several days based on the number of mailboxes you need to transfer from Local Exchange to Office 365. Other than that, you have no control over which data to transfer or filter.

Using an EDB converter tool, such as Converter Star for EDBYou can overcome these limitations and move all mailboxes at once from the on-premises Exchange database to an Office 365 tenant directly while saving significant effort and time.

The software provides a much faster, reliable and secure way to move mailboxes from the Exchange database to Office 365. It automatically maps the mailboxes of the source and destination – making your job easier. It also exports up to four mailboxes simultaneously to the target tenant of Office 365 – and speeds up the transfer process fourfold. You can download the free demo version to get started.

Setting up a Hybrid Exchange Office 365 server Is a recommended approach whether you want to move the entire Exchange to Office 365 or experience the best of both worlds. With more flexibility and scalability, Office 365 adds peace of mind while Exchange on-premises adds to data security as you can choose to keep your data at home.

After a hybrid deployment, if you want to eventually transfer completely locally to Office 365, you will need to stop publishing your local Exchange to the Internet after the transfer is complete. This is an important step in running a household that managers often overlook.
