Hi, is it possible to create a power automate flow to find submissions from users and as soon as MS has added a verdict to a submission as real phish send a notification back to the user who has reported it? Trying to figure out what is needed for such integration and build a flow but I am stuck. Anyone who has built that and like to share learning?
Keep user account but provision new empty mailbox
i did ask in another forum but thought i would ask here as it seems impossible... we are hybrid exchange. We have litigation hold and purview retention policies in place. We have a scenario where an existing user is moving to a new role and her existing mailbox needs to be dissociated from her AD account and a new clean mailbox provisioned. The original mailbox needs to stay as inactive and searchable via ediscovery. Is it possible? I have asked AI and its said: Make sure all the holds and retention policies are in place Move the AD account to a non-syncing OU and run a delta sync The mailbox should show as inactive in exchange online Then it tells me to run Set-User <UserUPN> -PermanentlyClearPreviousMailboxInfo but ONLY if the recipient type shows as MailUser or User This is where i am stuck as it is still UserMailbox. It told me to restore the cloud only object which i did. But it still shows as RecipientType = UserMailbox when i check. Its now just a cloud only account, it has no license. The mailbox is inactive but its still a UserMailbox Is what i am trying to do possible? Would now just changing the cloud only account to have a new email address be the only way to retain it and then sync back the on-prem account?Teams delegation permission issue with Onpremise Exchange Server

Thanks
Linking cloud only shared mailbox with onpremise object
Hi all, We currently have a cloud only shared mailbox in exchange online that we need to exist in onprem exchange for a smtp relay that is setup in a hybrid config. Is it possible to create onprem and match these objects onprem/cloud - or will the mailbox need to be recreated onprem and then it will sync to cloudHybrid Configuration Wizard fails to run – manifest download error on all machines
Hello, I am unable to run the Exchange Hybrid Configuration Wizard (HCW) for our Exchange 2016 environment. The issue occurs on multiple machines and networks, so it does not appear to be a local configuration problem. Environment: Exchange Server: 2016 CU23 Windows versions tested: Windows Server 2016, Windows 10 (all fully updated) .NET Framework: 4.8 (Release 528040 / 4.8.03761) TLS: TLS 1.2 enabled, SSL 3.0/TLS 1.0/1.1 disabled Network: No proxy, firewall, or other network restrictions; internet access available Problem: When attempting to run HCW via https://aka.ms/HybridWizard, the wizard fails to start. I have also tried to run HCW offline by downloading Microsoft.Online.CSE.Hybrid.Client.application, but it immediately fails. The error log shows the following repeated messages: Downloading file:///C:/Users/.../Application Files/Microsoft.Online.CSE.Hybrid.Client_17_1_3902_0/Microsoft.Online.CSE.Hybrid.Client.exe.manifest did not succeed. Could not find a part of the path 'C:\Users\...\Application Files\Microsoft.Online.CSE.Hybrid.Client_17_1_3902_0\Microsoft.Online.CSE.Hybrid.Client.exe.manifest' This occurs on all tested machines (three PCs across three different networks). ClickOnce cache has been cleared, root certificates are up-to-date, .NET is 4.8, and TLS 1.2 is active. Attempts to resolve: Ensured TLS 1.2 is enabled and default in .NET and OS Verified .NET 4.8 installation Cleared ClickOnce cache (rundll32 dfshim CleanOnlineAppCache) Updated root certificates Tried multiple machines and networks Tried to run offline using .application file and local copy of Application Files Result: HCW fails immediately with DeploymentDownloadException / DirectoryNotFoundException for the manifest. The issue is reproducible on all tested machines. Request: Please advise if there is an official offline installation method for HCW or a way to obtain a working manifest. If this is a temporary issue with the hosted distribution, please confirm expected resolution or workaround. Thank you for your assistance.
Exchange Online Mailbox cannot see Unsynchronized On-Premises mailbox Free/Busy info and vice versa
Hello Everyone! I originally posted an issue on Microsoft Learn https://learn.microsoft.com/en-us/answers/questions/5651848/free-busy-not-viewable-from-on-premises-mailbox-to?comment=answer-12418292&page=1#comment-2404594 regarding Free/Busy issues with our On Premises Exchange Server which is running the latest version of Exchange SE and Exchange Online which is on our Microsoft 365 Tenant. At first, it would fail the Test-OAuthConnectivity, but that now seems to be fixed with renewing the OAuth Certificate and in addition, enabling the Dedicated Exchange Hybrid App as per https://learn.microsoft.com/en-us/exchange/hybrid-deployment/deploy-dedicated-hybrid-app . On initial deployment, we could not see Free/Busy between EXO and On-Prem Exchange but after 2 hours, it started working but only between On-Premises Synchronized to Microsoft 365 Mailboxes and EXO Mailboxes Our final problem is the viewing of Free/Busy information of On-Premises 'NON-Synchronized to Microsoft 365' mailboxes and EXO Mailboxes. Running the Free/Busy Troubleshooter on ExRCA just gives me a warning during the Determining where the target mailbox is hosted. Also using 'Test-OAuthConnectivity -Service EWS -TargetUri https://outlook.office365.com/EWS/Exchange.asmx -Mailbox<onpremnonsynchedmailbox>@domain.com -verbose | fl ' on our On-Prem EMS leads to the following error System.Net.WebException: The remote server returned an error: (500) Internal Server Error. at System.Net.HttpWebRequest.GetResponse() at Microsoft.Exchange.Monitoring.TestOAuthConnectivityHelper.SendExchangeOAuthRequest(ADUser user, String orgDomain, Uri targetUri, String& diagnosticMessage, Boolean appOnly, Boolean useCachedToken, Boolean reloadConfig) ResultType : Error Identity : Microsoft.Exchange.Security.OAuth.ValidationResultNodeId IsValid : True ObjectState : New Please advise on how we can fix this error.
