It also assumes that you have an on-premises Exchange server in Hybrid mode with Office 365 / Exchange Online. What this script does is asks for the company being acquired Office 365 Global Admin Creds and dumps all the users, groups, group memberships, contacts, shared mailboxes, room mailboxes, equipment mailboxes, and user mailbox object. Imagine a scenario in which you created a migration batch and set to. In PowerShell, once you've connected to Exchange Online, you can run.

This describes how to fix the problem when a migration batch contains a mailbox that has an alias that isn’t in the Office 365 tenant and needs to be removed from the mailbox on-prem. If you only have a small number of mailboxes with errors then you can easily do this manually be removing the alias. If you have a large number of mailboxes simply removing the domains from the email address policy doesn’t remove the alias address from the mailboxes. You still need to run the command from the Exchange Management Shell:

In order to scriptthis out from Exchange On-Prem I first run an export of all mailboxes capturingall the email addresses of the mailboxes:

Login to the On-PremExchange server and run the Exchange Management Shell

Create a new foldercalled “Export” on the C: drive.

Run the followingcommands:

Now we need to openthe Excel file and make some modifications:

Firstly we need tocopy the Column C and paste it into Column E, then rename the headerAliasAddress

Next we need toperform a split on Column C, select the entire column, click the Data ribbon ofExcel and Text to Columns button. Choose the file type Delimited and clickNext. Deselect all options except Other and enter the symbol for colon “:”and click Finish. Label the Column D “Alias”.

Add one more Columnafter the C column and label it Primary. Enter the following formula in thecell for D2 “=IF(ISNUMBER(FIND(“SMTP”,C2)),”Primary”,“Alternate”)” and copy the formula down through all the Rows.

Now highlight Row 1,click the Home ribbon, click Sort & Filter and select Filter.

We should now have something that looks like this:

Each Row representsan address for the mailbox and we can now remove any addresses that will remainon the mailbox. The idea is to have a file with only addresses that should beremoved from mailboxes.

Filter on Column Dand only show those with a value of Primary, select all rows and delete therows, clear the filter on Column D.

Filter on Column Cand select X500 and X400 and delete all rows with those values, clear thefilter on Column C. We should be left with only values that have lowercasesmtp.

Now we are doingto create a Column to that will allow usto filter by domain name. Highlight Column F “AliasAddress” and clickthe Data ribbon and select Text to Columns. Select Delimited, click Next and thistime select Other with the symbol “@” and click Finish. We now have aColumn G that can be labeled “Domain” and it will have values for thedomain name. Filter the Column G “Domain” to only show domains thatare verified in the Office 365 tenant. You want to delete these rows from thespreadsheet.

The result is now anExcel spreadsheet that contains only smtp alias addresses for mailboxes thatwill be removed from Exchange On-Prem. Save the Mailboxes-Emailaddresses.csvfile.

Run the following script on the On-Prem Exchange Server to remove the smtp aliases on the mailboxes:

You can use the Migration dashboard in the Office 365 Exchange admin center (EAC) to manage mailbox migration to Office 365 using a cutover or staged Exchange migration. You can also use the Migration dashboard to migrate the contents of users' mailboxes from an on-premises IMAP server, or the contents of G Suite users' mailboxes, calendars, and contacts to existing Office 365 mailboxes. The Migration dashboard displays statistics about the overall migration in addition to statistics about a specific migration batch. You can create, start, stop, pause, and edit migration batches.

The Migration dashboard

To access the Migration dashboard in the EAC, select Recipients > Migration. The following screenshot identifies the different areas of the Migration dashboard that you can use to get migration information and manage migration batches.

Overall migration statistics

Click Status for all batches to display the overall statistics about all migration batches that have been created. The following fields display cumulative information about all migration batches.

Field	Description
Total mailboxes	The total number of mailboxes from all current migration batches.
Synced mailboxes	The number of mailboxes from all migration batches that were successfully migrated.
Finalized mailboxes	The number of mailboxes from all migration batches that have been finalized. Finalization occurs only when you use remote move migrations to migrate mailboxes between your on-premises Exchange organization and Office 365 in an Exchange hybrid deployment. Mailboxes can be finalized after the initial synchronization is successfully completed. For more information about finalizations in remote move migrations, see Complete-MigrationBatch.
Failed mailboxes	The number of mailboxes from all migration batches for which migration failed.

Migration batches

Migration batches that are created are listed in the migration queue. The following columns display information about each migration batch.

Column	Description
Name	The name of the migration batch that was defined when it was created.
Status	The status of the migration batch. The following is a list of the different status states for migration batches, along with what you can do with migration batches in each of these states: Stopped: Either the migration batch has been created but hasn't been started, or it has been stopped after running for some period of time. In this state, you can start, edit, or delete it. Syncing: The migration batch has been started, and mailboxes in the migration batch are being actively migrated. When a migration batch is in this state, you can stop it. Stopping: Immediately after you run Stop-MigrationBatch cmdlet. Stopped: The migration batch is stopped, and no more mailboxes from the batch are being migrated. When a migration batch is in this state, you can restart it. Starting: Immediately after you run Start-MigrationBatch cmdlet. Completing: Immediately after you run Complete-MigrationBatch cmdlet. Removing: Immediately after you run Remove-MigrationBatch cmdlet. Synced: The migration batch has completed an initial sync of the data. A migration batch in this state may contain errors if mailboxes weren't migrated. For most types of migrations, the remote/on-premises mailboxes and the corresponding Office 365 mailboxes are synchronized every 24 hours during incremental synchronization. Completed: The migration batch is complete. Synced with errors: The migration batch has completed an initial sync of the data, but some mailboxes failed migration. Mailboxes that were successfully migrated in migration batches with errors are still synchronized every 24 hours during incremental synchronization.
Total	Indicates the number of mailboxes in the migration batch.
Synced	Indicates the number of mailboxes that were successfully migrated.
Finalized	The number of mailboxes in the migration batch that have been finalized. Finalization is performed only for migration batches for remote move migrations in an Exchange hybrid deployment. For more information about the finalization process, see Complete-MigrationBatch.
Failed	The number of mailboxes in the migration batch for which the migration failed. You can display information about specific mailboxes that have migration errors. For more information, see Migration users status report.

Important

Migration batches with a status of Synced that have no administrator-initiated activity (for example, no administrator has stopped and restarted a migration batch or edited a migration batch) for the last 60 days will be stopped. All batches with Stopped or Failed status will be removed after 90 days. All batches with Completed status will be removed after 60 days.

The Migration dashboard contains a set of commands that you can use to manage migration batches. After you create a migration batch, you can select it, and then click one of the following commands. If a migration batch is in a status state that isn't supported by a command, the command is either dimmed or not displayed because it's unavailable. Telugu music directors mp3 collection 2017.

Command	Description
New	Create a new migration batch. Use this command to migrate on-premises mailboxes to Office 365 (also called onboarding) or to migrate Office 365 mailboxes back to your on-premises Exchange organization in a hybrid deployment.
Edit	Edit an existing migration batch. You can change the finalization semantics of batches that support finalization. You can also change the migration endpoint used for the migration batch.
Start	Start a migration batch that's been created. After the batch is started, the status is changed to Syncing.
Resume	Resume the running of a migration batch that was paused and has a status of Stopped. If there are errors for a migration batch, you can restart it with this command, and Office 365 will attempt to migrate the mailboxes that failed.
Pause	Stop a migration batch that's currently running or that's been started but has a status of Queued. You can also stop a migration batch that's completed the initiation synchronization phase and has a status of Synced. This will stop incremental synchronizations. You can resume incremental synchronizations by selecting the migration batch and clicking Resume.
Delete	Delete a migration batch after you verify that all mailboxes in the migration batch have been successfully migrated. Verify also that mail is being routed directly to cloud-based mailboxes after you've configured your MX record to point to Office 365. When you delete a migration batch, Office 365 cleans up any records related to the migration batch and removes it from the list.
More	Click this command, and then click Migration endpoints to create new migration endpoints or view and edit existing migration endpoints.
Refresh	Refresh the Migration dashboard to update the information displayed for the overall migration statistics, the list of migration batches, and the statistics for the selected migration batch.

Migration batch statistics

The details pane in the Migration dashboard displays the following information about the selected migration batch.
