Cross-Tenant Mailbox Migration - HTTP 401 Unauthenticated during Test-MigrationServerAvailability
We are performing a Cross-Tenant Exchange Online mailbox migration between two Microsoft 365 tenants. The migration endpoint is configured with ApplicationId authentication and validates successfully. When running: Test-MigrationServerAvailability -Endpoint "MexicoToPortugal" -TestMailbox "<user>" the test consistently fails with: StatusCode="Unauthenticated" HTTP Status Code: 401 We reproduced the issue with two different users. We have already validated: - MailUser configuration - ExchangeGuid - LegacyExchangeDN (X500) - ExternalEmailAddress - Accepted Domains - Organization Relationships - Migration Endpoint - Enterprise Application - Mailbox.Migration permission - Admin Consent - Cross-Tenant Migration licensing The same HTTP 401 error occurs for multiple mailboxes after all configuration issues are corrected. Has anyone experienced a similar Cross-Tenant Mailbox Migration scenario where Test-MigrationServerAvailability returns HTTP 401 Unauthenticated even though the Enterprise Application, Mailbox.Migration permission and Admin Consent are correctly configured?Retirement of Azure Communication Services

Exchange 2010 to Microsoft 365 Migration – Recommended Approach and Tools
I’m looking for guidance on migrating Exchange 2010 (on-premises) to Microsoft 365 / Office 365. Is a direct migration from Exchange 2010 supported, or is an intermediate hop (such as upgrading Exchange or setting up a hybrid configuration) required? Additionally, could you please recommend any reliable tools that can help with this migration? I also have a few PST files that need to be migrated as part of the process. I’d appreciate insights on best practices, common challenges, and lessons learned from real-world migrations. Thanks in advance for your help.

Permission activesync on smartphone
Hi everyone, when you grant the permissions in question to manage company email from a smartphone, do these permissions, in addition to Remote Wipe, Password Enforcement and Device Encryption (I remember these as the main ones), somehow give the Exchange administrator access to my personal data? For example, photos, any documents saved on the SD card or on the smartphone itself? Thanks in advanced!Outlook Desktop users continually prompted for credentials On-Prem Exchange SE
Battling ongoing issues with users being continually prompted for password using Outlook 2024 LTSC with on-prem Exchange 2019 SE. Removed Windows credentials, turned off cache mode, removed shared calendar(s), outlook connection status seems fine. Only (temp) workaround seems to be removing mail profile and recreating it. All other network resources on domain are fine. Any input appreciated. Thanks
