Shared Mailbox Migration in Office 365
Cloudiway’s mailbox migration tool has a separate migration list to manage the migration of shared mailboxes between Office 365 Tenants. This migration tool can be used to identify shared mailboxes in the source tenant and populate the migration list, as well as provision shared mailboxes in the target.
The setup and usage of this tool are the same as migrating standard mailboxes. If you have not already set up your project and tenants for a mailbox migration be sure to follow the mail migration admin guide prior to migrating shared mailboxes – https://cloudiway.com/resources/documentation/office-365-mail-migration/.
To use the shared mailbox migration list, open your migration project and navigate to the Mail Migration area. There you will see a Shared Mailboxes section. In this list, you can click on the Manage drop-down menu to populate the migration table with either a CSV import or by manually creating entries one at a time.
You can also select the Migration drop-down menu and use the Get List option to automatically detect shared mailboxes and populate the migration table. When using this option, you must specify the source and target connector, as well as the type of target mailbox you want to migrate to (standard, archive, or shared) and target mailbox email address format. Select the Matching Rule drop-down menu to choose from different email prefix rules, and then choose the target domain to set in the list. In Office 365 migrations you will use a matching rule other than “Mail Exact Match” and you will need to specify the target email domain name. This is because two Office 365 tenants cannot actively use the same domain name at the same time.
Once your list is populated, if you want the Cloudiway tools to create the target shared mailboxes you can select the items you want to provision and click on the Migration drop down menu and choose Pre-Processing. If you have already provisioned the target shared mailboxes a different way, you can select the items you want to migrate and choose Migration à Start and your migration will begin.
Google Workspace Shared Mailboxes
In Google Workspace tenants, the concept of a shared mailbox is handled a bit differently. You could be using Google Groups Collaborative Inbox, for which Cloudiway offers a separate migration tool, or you could create a user mailbox and delegate access to it. Technically the Shared Mailboxes section of the Cloudiway Mail Migration tool can be used to migrate these delegated access user mailboxes, but you will need to manually import or populate the migration list and be sure you do not duplicate source mailboxes in the standard user migration list.
