How many mailboxes can i move

Does completing a batch perform a delta sync before actually cutover the mailbox? Yes, it will perform a delta sync every day and then when you complete the migration it will lock the mailbox briefly and perform a final delta sync. Can mailboxes which have failed to synchronize successfully be completed without re-mediating the corruptfolderACL item. Re the other guff..

ITs all so connected.. Thanks for sharing! Hi Steve A great article, thanks. I am wondering what the issue is with using autocomplete? Is it just the convenience of narrowing down the time to complete the migration? I am guessing it is only the VIP list that want to be hand held to reattach Email to their phones? Would you use autocomplete for standard users, calendars, and shared mailboxes? If we set a migration limit of say 20, it will keep migrating up to 20 at one time until the whole batch is finished, will it not?

For a user on a PC, as their mailbox completes Outlook just pops up a message asking them close and reopen Outlook. I would always recommend keeping user disruption to a minimum, so if we can choose when migrations complete, rather than they simply complete when they are ready we will have a better experience. There are factors like ensuring that people who share calendars with each other move at the same time and so on which are important for the way people use Exchange and in general we want to move people who share together at the same time.

I would personally suggest switching out of hours for big batches of users so that they simply launch Outlook and with Modern Auth, modern clients etc everything continues to work; and their colleagues are moved at the same time.

That should give the best of both worlds. First… I am unable to segregate more than one and if lucky two email addresses to a new batch for isolated completion. More than one or two email addresses ends up throwing an error. Steve, I appreciate all you do for the community, but this article has not been vetted and is a hard pass for me. I appreciate you messaged me because you wanted to use a variation of the technique for an in-progress migration you were struggling with.

But not that it should matter, right? It is dependent on the time of the daily sync and the amount of changes across every mailbox in the org.

We can choose when the migrations are scheduled to begin the completion process however, we cannot choose when they complete. That is all dependent on several factors … location of mailbox, size of mailbox, changes to mailbox, connectivity, etc. Column A is the email address of the Office mailbox. Column B is the sign-in name for the user's Gmail mailbox —for example, alberta contoso. Column C is the app password for the user's Gmail mailbox.

Creating the app password is described in Migration from G Suite mailboxes using the Office admin center. Save the file as a CSV file type, and then close Excel. Click Next. The migration service uses the settings to test the connection to Gmail system. If the connection works, the Enter general information page opens.

On the Enter general information page, type a Migration endpoint name , for example, Test5-endpoint. Leave the other two boxes blank to use the default values.

Click New to create the migration endpoint. Click Close on the Migration Endpoint page. Step 5 - Create a migration batch in EAC and start migrating Gmail mailboxes Use a migration batch to migrate groups of Gmail mailboxes to Office at the same time. After you select your migration file, Office checks it to m ake sure: It isn't empty.

It uses comma-separated formatting. It doesn't contain more than 50, rows. It includes the required attributes in the header row. It contains rows with the same number of columns as the header row. If any one of these checks fails, you'll get an error that describes the reason for the failure.

If you get an error, you must fix the migration file and resubmit it to create a migration batch. After Office validates the migration file, it displays the number of users listed in the file as the number of Gmail mailboxes to migrate. On the Set the migration endpoint page, select the migration endpoint that you created for Gmail in the previous step, and click Next.

On the Move configuration page, type the name no spaces or special characters of the migration batch in the box—for example, Test5-migration. The default migration batch name that's displayed is the name of the migration file that you specified. The migration batch name is displayed in the list on the migration dashboard after you create the migration batch. You can also enter the names of the folders you want to exclude from migration.

For example, Shared, Junk Email, and Deleted. You can also click Edit to change a folder name and Delete to delete the folder name. You can also define the Bad item limit and Large item limit.

Click Next On the Start the batch page, do the following: Choose Browse to send a copy of the migration reports to other users. By default, migration reports are emailed to you. You can also access the migration reports from the properties page of the migration batch.

The migration starts immediately with the status Syncing. If you have large user mailboxes and the status shows Syncing for a long time, you may be experiencing bandwidth limits set by Google. For more information, see Bandwidth limits and Sync limits. You can try to unlock the Gmail user or use alternative method to migrate the users. For more information, see Use network upload to import your organization PST files to Office and Third-party tools for Office migrations.

Verify that the batch is displayed in the migration dashboard. You can also create a Smart Mailbox by copying and editing an existing one. If you change an email while viewing it in a Smart Mailbox—such as marking the email as read or unread, or moving or deleting it—the change is reflected in the mailbox where the email is stored.

See Use iCloud Drive to store documents. Enter a name for the Smart Mailbox. Specify the criteria. Click OK.
