Migrate Office 365 Group mailbox

Migrating an Office 365 group mailbox is essential for businesses facing mergers or tenant consolidations. Office 365 groups enhance collaboration by integrating shared inboxes, calendars, and document libraries. Their automatic permission setup ensures seamless access for new members, making them a modern alternative to traditional shared mailboxes and distribution lists. However, migrating these groups' mailboxes involves more than just moving emails—it's about transferring an entire collaborative workspace.

This is where the EdbMails Office 365 migration tool comes into play. It’s designed to make migrating Office 365 group mailboxes easy and efficient with zero downtime for your team. With EdbMails, you can migrate multiple Office 365 group mailboxes simultaneously, thanks to its concurrent migration feature, which saves time and speeds up the entire process. Additionally, EdbMails automatically handles throttling Microsoft’s way of limiting data flow to avoid overloading its servers so you don’t have to worry about interruptions or delays during the migration. You’ll also get detailed migration reports that give you a clear view of what’s been transferred, along with the status of the process, which makes it easy to track progress and spot any potential issues. With these key features, EdbMails ensures that migrating your Office 365 group mailboxes is a smooth, secure, and hassle-free experience.

2. Office 365 Groups to another tenant migration using EdbMails

   • Step 1: Download and install EdbMails software

     • Download and install EdbMails software on your computer.

        See a detailed list of EdbMails system requirements for Office 365 migration.

       

     • After you have installed it, click ‘Start Your Free Trial’ to start using the application.

       

     • Select ‘Office 365 Migration’ from the main screen.

       

       Note: If the Standard folders (such as Inbox, Calendar, Contacts) on your source server mailboxes are initialized with a different language, follow the details to migrate these folders to the respective system folders on the target (destination) server.

       For Instance: If your source Inbox folder is named 'Boîte de réception', which is in French language and you migrate this folder directly to the destination server, then by default it will not be mapped to the 'Inbox' folder on the target server. In order to map the folder with the french name to the respective folder, change the regional settings on the target server to match that of your source mailbox folder language (in this case, it is French).

        Steps to change the language and regional settings on Office 365

   • Step 2: Log in to the source Office 365 account as Administrator

     • To migrate Office 365 Groups, you need to log in to your Office 365 tenant account. 
     • Enter your credentials and click the ‘Login’ button.
     • EdbMails is a highly secure application and supports OAuth 2.0 authentication along with TLS encryption. 
     • Select the connection method as ‘Connect to Mailboxes(es)’

      Connect to Office 365 server using secure modern authentication

     

   • Step 3: Select the source Office 365 Group for migration

     • EdbMails displays all the groups and associated mailboxes from your Office 365 tenant. 
     • Select the group or groups that you want to migrate to the target and click ‘Migrate to Office 365’. You can select the required group by browsing through the list of groups.

      Tip: In addition to the group migration, you can also export mailbox to PST from Office 365

     

   • Step 4: Log in to the target Office 365 tenant as Administrator

     • Select the preferred method for secure OAuth-based modern authentication. The default option, ‘Auto Registration’, requires Global Admin permissions for configuration, ensuring a streamlined setup process. Alternatively, the ‘Manual Registration’ option provides greater flexibility, as it can be completed using either a Global Admin account or any user account with the necessary full access privileges.

       

     • Next, select the most suitable migration option and proceed by logging into the Microsoft sign-in page to authenticate your account.

       

     • EdbMails automatically loads mailboxes from your source server. Additionally, it supports the use of CSV files to efficiently load mailboxes into Office 365.

       

   • Step 5: Maps the source and target servers

     • Select the mailbox mapping option that best aligns with your requirements.

       

     • EdbMails simplifies the migration process with automated mailbox creation for Office 365, ensuring precise mapping of mailboxes and folders from the source IMAP server automatically. This feature is crucial for large-scale migrations, optimizing the workflow and ensuring a seamless transfer to Office 365 without manual intervention.

       

     • Click the ‘Folder and Item Filter’ button to set a filter for your migration. For instance, you can choose to migrate data only within a specific date range by applying a date filter. Additionally, you can exclude both standard and custom folders from the migration.
