What You Need to Know

Simplifying On-Premises to Office 365 Migrations

Migrating from an On-Premises Exchange environment to Office 365 is a major step for any organization looking to embrace the flexibility and scalability of cloud-based email. However, the technical details and user experience during and after migration can raise a number of questions. Here’s what you need to know about how Promodag Reports streamlines this journey and make post-migration management easier than ever.

Seamless Directory Import and Recipient Linking

Once a mailbox migration from your on-premises Exchange Server to Office 365 is complete, the directory import process kicks in to detect and handle the new state of your mailboxes.

Here’s what happens:

  1. Remote Mailbox Creation: Your old on-premises mailbox is automatically converted into a Remote Mailbox.
  2. Office 365 Mailbox Setup: A brand-new Office 365 mailbox is created.
  3. Recipient Linking: Promodag Reports links the new Office 365 mailbox with the original on-premises user account.

This linking is crucia for it ensures that any recipient selection such as those in address books or distribution groups that were created before the migration continue to work seamlessly. When you reference an old on-premises mailbox, it’s automatically replaced by its new Office 365 counterpart, even in bulk selections like distribution lists. This minimizes disruption, keeps communication flowing, and reduces confusion for both users and admins.

Effortless Data Migration

One of the challenges with mailbox migrations is ensuring that historical data—emails, and storage—is not left behind. To address this, a tool is included in the product that allows you to move previously imported traffic and storage data from the old (on-premises) mailbox to the new (Office 365) mailbox. This means users retain access to their complete email history without complicated manual transfers or data loss. Please contact the Promodag support to help you perform this operation.

Enhanced Recipient Management

Managing users across hybrid environments can be tricky. The context menu provides a direct way to navigate between Office 365 recipients and their on-premises counterparts. Whether you’re tracking a migration or troubleshooting, this feature makes it easy to view and manage linked accounts.

Drilling down into Recipient Properties

Once the Exchange recipient has been located in the Organization tree, you can easily examine its properties. This includes viewing key attributes such as storage limits and all associated addresses, whether SMTP, X500, or others. Having this information at your fingertips is invaluable for day-to-day administration and troubleshooting.

Powerful Recipient Search

Finding the right recipient quickly is a must in any large organization. The Organization tree includes a powerful search box, letting you find recipients by name—no matter where they reside in your Exchange environment. You can enter a string for partial matches, and the built-in counter shows you how many matches were found. Convenient arrow buttons let you jump between results, making management faster and more efficient.

Advanced Message Listing for eDiscovery and Message Migration Check

Finally, we’ll highlight a particularly useful—if sometimes overlooked—feature, especially valuable for eDiscovery or forensic searches: listing all messages related to a specific recipient.

Why is this important?

If you ever need to quickly determine whether a message was sent or received by a mailbox—perhaps for compliance, internal investigation, or legal reasons, this feature is a game-changer. It also helps verify that messages linked to a recently migrated mailbox have been moved to the new Office 365 mailbox.

How it works:

  1. Select the Recipient: Point to the recipient in the Organization tree, then right-click and select “Linked messages.”
  2. Choose the Period: Specify your desired search dates, then click List messages. The resulting grid displays all relevant messages, which you can sort, and filter as needed.
  3. Refine Your Search: For more advanced queries, use the Filter Editor in the bottom right-hand corner of the grid. For example, filter messages whose subject contains “iPad” to quickly zero in on relevant communications.

With automatic recipient linking, seamless data transfer, context-aware navigation, detailed recipient property views, and robust eDiscovery features, managing a hybrid or fully cloud-based Exchange environment becomes straightforward and user-friendly.
