Litigation Hold Mailbox Migration
My company is currently moving from Exchange 2016 to 365. We are currently setup in a hybrid environment. The question arose of how do we migrate mailboxes that are on litigation hold. I have found that you can do a migration of the lit hold mailboxes from on-prem to 365 without any issues per this document - https://learn.microsoft.com/en-us/exchange/policy-and-compliance/holds/holds?view=exchserver-2016#migrating-mailboxes-on-hold-from-exchange-server-to-microsoft-365-or-office-365. However, what I can't seem to find is the best way to test a migration for a lit hold mailbox. I also have found that some of our lit hold mailboxes have been on hold so long that their mailboxes are on Exchange version 0.10. So, I really have 2 questions. 1) How can I test migrating a lit hold mailbox from on prem to 365 without using an active person's mailbox? 2) Does the Exchange Version for the mailbox matter when I migrate them? Any help would be much appreciated.
GoDaddy to Microsoft 365 Migration Issues
Hi there, I wonder if I could get some help with an issue I've got. Currently I am attempting to migrate one user mailbox from the current GoDaddy tenant to our new Microsoft tenant, to initially test out the migration. I've followed the Migration tool in the Exchange admin center but am receiving the following error: Error: MigrationRecipientNotFoundException: A recipient wasn't found for "***@***.onmicrosoft.com". Create a recipient of the appropriate type for this migration and try again. I've got the user created in the Microsoft 365 admin center and a mailbox is set up for them. Both on GoDaddy and Microsoft it is UserMailbox recipient type. I'm using the IMAP Migration settings as outlined from the GoDaddy IMAP settings, and have since checked with GoDaddy and they give these settings: IMAP Server: imap.secureserver.net Authentication: Basic Encryption: SSL Accept untrusted certificates: Yes Port: 993 GoDaddy have also said that Basic authentication is supported by them and I have checked the Entra configuration to ensure that Basic is not blocked. I have even had the user I'm attempting to migrate log in to the temporary onmicrosoft account to make sure there are no log in issues there. I have posted this on the Answers forum as well and was pointed in this direction for further help. Any thoughts or help on this would be amazing. Thanks in advance, OliMigrating from Google Workspace to Microsoft 365 with to have two separate Mailboxes per User + SSO
Context and Requirements: My company (abc.com) is being acquired by another org (xyz.com). We’re currently on Google Workspace (G Suite) for abc.com email and want to migrate everything (email, calendar, contacts) into Microsoft 365 — specifically into the xyz.com tenant. After migration, each user must have two fully separate mailboxes: Mailbox A: email address removed for privacy reasons (data migrated from G Suite) Mailbox B: email address removed for privacy reasons (new mailbox in the xyz.com tenant) We need true single sign-on (SSO) so users can log in once and access both mailboxes (not just alias addresses) within the same tenant. We want to minimize complexity. FYI we will set up abc.com as an Accepted Domain in xyz.com Microsoft Exchange tenant. What I’ve Investigated So Far: Migration Tools: The Exchange Admin Center has a built-in G Suite migration wizard, but it mainly migrates mail to one mailbox. Third-party tools like BitTitan MigrationWiz can also handle G Suite → M365 migrations. Two-Mailbox Setup Approaches: One licensed mailbox + one shared mailbox: For example, the user’s main mailbox would be email address removed for privacy reasons (fully licensed with migrated data), while email address removed for privacy reasons is a shared mailbox to keep it separate. The email address removed for privacy reasons account gets Full Access and Send As permissions on the xyz.com mailbox. Pros: Single sign-on, one set of creds, minimal extra licensing. The data stays separate (two distinct mail stores). Cons: Shared mailboxes are limited to 50GB if unlicensed, and some compliance features may require a license. Two fully licensed user mailboxes (two Azure AD user accounts, e.g. email address removed for privacy reasons and email address removed for privacy reasons): Each mailbox is completely independent, but typically requires two sign-ins unless there’s advanced identity federation to unify credentials. Also doubles the licensing. Pros: Full feature set in both mailboxes, no shared mailbox constraints. Cons: Additional license costs, and not a straightforward “one-click” SSO for both. Questions Which approach is best for maintaining two discrete mailboxes per user without forcing them to manage multiple logins? Are there any best practices for migrating from Google Workspace into Exchange 365(specific tenaant) maintaining the same email address? Have you run into compliance or eDiscovery issues with a shared mailbox approach? Any caveats or special steps needed to ensure calendars and contacts migrate correctly from Google Workspace into the new environment?
Help with 365 migration please
Can anyone help me with this Migration please. The tenancy has existed for some time and all users have had a business standard license to enable them to use Teams and Office 365 for some time. This means that mailboxes were created automatically but these have never been used. AD Sync was in place. I am trying to migrate from Exchange 2016 to 365. I have: Checked each user has an e-mail alias in Exchange @leonardgray.onmicrosoft.com. Configured Outlook Anywhere on my on-premises Exchange Server. Enabled MRS Proxy on your on-premises Exchange Server. Use the Microsoft Exchange Remote Connectivity Analyzer to test your connection settings. Used the Outlook Anywhere (RPC over HTTP) or Outlook Autodiscover tests - it is showing no issues. Checked the permissions on the account I'm using to migrate (domain admin and has FullAccess and assigned WriteProperty permissions). We're not on Exchange server 2007 so no need to worry about unified messaging. The domains are verified. The users are created licensed. I have the CSV with the list of users. I've created a variety of migration endpoints and it verified as it saved and saved successfully. I initially tried to use a cutover migration as it is what I have used successfully in the past. This failed, when I researched the error the articles suggested that it was because AD sync was in place. So I turned off AD sync. The cutover migration continued to fail. The articles suggested that a Staged migration was a better option for this scenario. This failed with this error: Error: MigrationTransientException: Failed to update the on-premises mailbox with the target address (SMTP:email address removed for privacy reasons). The mail sent to the user will not reach user's hosted mailbox. The error might be due to account credentials used for migration not having enough permission to write data back into the on-premise AD. Please ensure that the account credential has Domain Admin privilege. --] We weren't able to connect to the remote server. Please verify that the migration endpoint settings are correct and your certificate is valid, and then try again. Consider using the Exchange Remote Connectivity Analyzer (https://testexchangeconnectivity.com) to diagnose the connectivity issues. I did some more reading and found an article that suggested that Staged migrations can only be used from Server 2003 and 2007. So I decided to try a Remote Migration. This one failed with the error: Error: TargetUserAlreadyHasPrimaryMailboxException: Target user '902b455c-5986-47c7-9988-bb7282df52b5' already has a primary mailbox. The articles about this suggest I need to delete the data in homeMDB and homeMTA. The data in homeMDB looks like a pretty important link between Exchange on prem and Active Directory. I'm not particularly comfortable with just deleting this. Can anyone tell me what I'm missing?

Tenant to tenant mail migration from large to small organization
According to Microsoft sales team the answer in this thread is most likely wrong! Can you confirm that? (commenting is not possible anymore) We are a small group in a very large organization now established as an independent company. A very common situation. New licenses for Office365 including everything and all premium have been acquired for our small independent group. The very reason to continue using Office365 is to ensure a smooth migration of Outlook mail including calendar, and only spending a minimum of time on related tasks. MS sales team advice that you can do a migration as in these guides, but you require "Cross Tenant User Data Migration", which only is available to "Enterprise Agreement" customers - and of course not for our small group. How can we quickly and smoothly do the migration? In case of a work-around like exporting data to a PST-file, then please observe that this task must be completed in the web app, and we cannot achieve admin privileges in the large organization. The question has been migrated from here.
