How to Reassign an EmailMerge365 License to a New User

Overview

An EmailMerge365 license can be moved from an existing user to another user. The old user must first be removed from both Microsoft 365 and the EmailMerge365 Management Console. Because Microsoft controls add-in deployment and removal, each change may take up to 72 hours to fully propagate in Outlook.

Steps

Remove the existing user in Microsoft 365

Sign in to the Microsoft 365 Admin Center.
Go to Integrated apps and select EmailMerge365.
Remove the user whose license you want to reassign.

Remove the existing user from EmailMerge365

Sign in to the EmailMerge365 Management Console.
Locate the same user and remove them from the subscription.

Allow time for removal

Wait for the EmailMerge365 add-in to be fully removed from the existing user's Outlook.
This can take up to 72 hours, depending on Microsoft's deployment process.

Assign EmailMerge365 to the new user

Once the add-in has been removed from the previous user's Outlook, return to the Microsoft 365 Admin Center.
Under Integrated apps, select EmailMerge365 and add the new user's email address.

Allow time for the new deployment

Microsoft may take up to 72 hours to propagate the EmailMerge365 add-in to the new user's Outlook.

Important Note

The removal and deployment timing is controlled by Microsoft 365. Although changes may appear sooner, allow up to 72 hours for each stage to complete before running the deployment.
