Automatic redirection of Exchange ActiveSync On-Pre
I am migrating mailboxes between on-premises Exchange forests using ADMT automated calls in SC Orchestrator 2019. Prepare-MoveRequest Migrate-ADMTUser MoveMailbox Set-Resources Has anyone already done the automatic redirection of Exchange ActiveSync in the following scenario: Moving mailboxes between on-premises Exchange organizations. I know the link below says it is not possible, but I would like to know if anyone has overcome this limitation? https://learn.microsoft.com/pt-br/exchange/activesync-settings
Exchange SMTP Auth Fails with: 451 4.7.0 Temporary server error. Please try again later. PRX5
Office 365 refuses SMTP authentication with error: 451 4.7.0 Temporary server error. Please try again later. PRX5 This is when accessing External Send SMTP AUTH through OAUTH2 authentication. Initial authentication is successful (and is logged as so in Entra ID) but when trying to send send messages through authenticated SMTP, you get the above error. Working with multiple support reps, we looked through login logs and could not find any trace of the error in Entra ID. Support reps all blame the third party application. The issue is connected to a special use case, where a user has both the GLOBAL ADMIN role, as well as certain other admin roles. When you have a certain combination of those roles, for a selected user, OAUTH2 will fail, even though OAUTH2 for (apparently) ALL OTHER SERVICES - work without error! - ONLY SMTP Auth is affected. RESOLUTION: Keeping Global Admin while simply removing excess roles will almost immediately resolve the issue. This bug has been publicly noted as far back as August 2022, perhaps earlier. This needs to be fixed.
SMTP Issue - Exchange 2019
Hi All, I have an hybrid exchange environment (365 + 2019), and the onprem server is used for smtp relay only. An internal app uses this relay and send email as "email address removed for privacy reasons", and all works well except by an specific message-subject. This application can send all the emails with any subject, but if the subject is "Purchace Order to be approved" the relay fails. Checking logs, I could see that when the message has this mentioned subject then the field "sender-address" is always empty (return-path is ok). And, of course, SPF/DKIM fails and message is quarantined. All other message subjects contain the address in "sender-address". This could be an issue with my application or something related to smtp config?

Delegating permission to approve Quarantined Mobile Devices in Exchange Online
Hi all, I would appreciate some guidance. Today, we are configured to quarantine any mobile device that attempts to add their mailbox to their device. We have three administrators that can approve these devices. I'd like to delegate this responsibility to the person on our team who stages and deploys mobile devices without giving them full administrator access. Additionally, I am looking to grant access within the GUI, not the ability to run a PowerShell cmdlet. From this post on Reddit, I first attempted this process, but it did not seem to work. In the GUI, a user in the group I created cannot access the Mobile Devices page in the Exchange Admin Center. I then attempted this link to Microsoft documentation, but it doesn't seem to fit exactly. Granted, I don't have much experience with Exchange permissions. Any help, guidance, or direction you could point me in would be greatly appreciated. Thanks SteveInstall exchange server Error :
