Need Help in Migrating Office 365 Mailbox to Another User

Hello everyone,

My organization has just finished migrating another company into our Office 365 tenant. We have also created the same user accounts under our existing tenant – in simple words, we now have the same users twice – one with the old-username/mail@domain and one with the new-username/mail@domain – so what are the reliable approach to migrate data to mailboxes so all the emails from the old-username/mail@domain get transferred/migrated/ into the new-username/email domain without losing a bit of data?

I don’t want the classic PowerShell approach, as I don’t have the technical knowledge. I am looking to automate this task as much as possible. Suggest us any software that can help to get this done. Thanks in advance.

Scenario:

There are two ways to perform the above operation first is the manual method using the PowerShell scripts and the second is using the automated software. However, the manual approach has many challenges and it can make this task tedious and cumbersome.

Here are a few of the challenges or complications that may arise while performing the same through the conventional approach:

1. The first challenge that you may see is that a custom Office 365 domain cannot become in use in two different Office 365 tenants. It should detach from the source tenant before adding to the destination tenant.
2. Whenever a temporary or permeate username gets changed then the Office 365 account’s mailbox identities could possibly get changed. Moreover, MS Outlook also needs to be reconfigured in these cases. That can create multiple errors and confusion while performing the same operation.
3. The biggest challenge is that the respective passwords cannot be migrated to the destination Office 365 account if the user is using the DirSync, local AD accounts.

These are the few complications that are being shown in the above section. There are way more limitations and drawbacks of using the conventional approach for this operation. Here is the best solution to get rid of all these complications.
