Tenant to tenant mail migration from large to small organization
According to Microsoft sales team the answer in https://answers.microsoft.com/en-us/msoffice/forum/all/migrating-email-from-one-office365-account-to/da67871d-10b3-40d3-9108-cbd0a020c917 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 https://learn.microsoft.com/en-us/microsoft-365/enterprise/cross-tenant-mailbox-migration?view=o365-worldwide, 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.

365 Tenant To Tenant Migration
I have a tenant who is not set up to be GCC compliant. We have created another tenant that is now GCC compliant and need to move the tenants from the original tenant to the newly created GCC compliant tenancy. I am not sure how we can go about doing this with the destination and origination having the same domain name. I have created the users with the onmicrosoft accounts, instead of the .org users, but we still have the issue of migration. How do we move these users? What is the expected down time for their domain if we use a dummy domain? I am very concerned this is going to result in a massive loss of data.Teams Delivers a Slack Migration Tool
Microsoft announced the availability of a Slack to Teams migration tool in the Microsoft 365 admin center. The new tool exists to assist the 79 million monthly active users of Slack who might want to move to Teams and don’t know how to get there. ISVs have been helping people move off Slack to Teams for years, so other migration options exist. https://office365itpros.com/2026/01/07/slack-to-teams-migration/
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, Oli
Issue when ingesting Defender XDR table in Sentinel
Hello, We are migrating our on-premises SIEM solution to Microsoft Sentinel since we have E5 licences for all our users. The integration between Defender XDR and Sentinel convinced us to make the move. We have a limited budget for Sentinel, and we found out that the Auxiliary/Data Lake feature is sufficient for verbose log sources such as network logs. We would like to retain Defender XDR data for more than 30 days (the default retention period). We implemented the solution described in this blog post: https://jeffreyappel.nl/how-to-store-defender-xdr-data-for-years-in-sentinel-data-lake-without-expensive-ingestion-cost/ However, we are facing an issue with 2 tables: DeviceImageLoadEvents and DeviceFileCertificateInfo. The table forwarded by Defender to Sentinel are empty like this row: We created a support ticket but so far, we haven't received any solution. If anyone has experienced this issue, we would appreciate your feedback. Lucas
