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?106Views0likes2CommentsTeams calendar for exchange on prem users not working

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.416Views0likes2CommentsExchange 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.104Views0likes1CommentNeed to Purge DiscoveryHolds Data from Archive Mailbox in Exchange Online
Hello Team, I am working on an Exchange Online mailbox where the archive mailbox has accumulated a large amount of data (over 335 GB) under the Recoverable Items → DiscoveryHolds folder. The mailbox is not on Litigation Hold or Retention Hold, and the InPlaceHolds property shows exclusions (-mbx...), so there are no active holds preventing deletion. Environment Details Service: Exchange Online Mailbox: email address removed for privacy reasons Archive mailbox size: ~335 GB DiscoveryHolds subfolders contain the bulk of the data. Background : Initially, the user’s primary mailbox was full because more than 100 GB of data resided in the Recoverable Items folder of the primary mailbox. Since I was unable to delete the data, so as a workaround, I enabled the archive mailbox and moved the data there. I have raised multiple tickets with Microsoft, but after more than 45 days, I still do not have a proper resolution. Mailbox Hold Status PS H:\> Get-Mailbox -Identity email address removed for privacy reasons -Archive | fl *hold* LitigationHoldEnabled : False RetentionHoldEnabled : False EndDateForRetentionHold : StartDateForRetentionHold : LitigationHoldDate : LitigationHoldOwner : ComplianceTagHoldApplied : True DelayHoldApplied : False DelayReleaseHoldApplied : False LitigationHoldDuration : Unlimited SCLDeleteThreshold : SCLRejectThreshold : SCLQuarantineThreshold : SCLJunkThreshold : InPlaceHolds : {-mbx23233XXXXXX, -mbx212433XXXXXX} RecipientThrottlingThreshold : Standard PS H:\> Get-MailboxFolderStatistics -Identity email address removed for privacy reasons -Archive -FolderScope RecoverableItems | ft Name,ItemsInFolder,FolderAndSubfolderSize Recoverable Items : 0 335.2 GB DiscoveryHolds : 80495 335.2 GB DiscoveryHolds_2022 : 177 20.7 MB DiscoveryHolds_2023 : 350 88.12 MB DiscoveryHolds_2024 : 4117 1.34 GB DiscoveryHolds_2025 (multiple subfolders): 47 GB – 55 GB each Issue : I need to purge only the DiscoveryHolds data from the archive mailbox without affecting other folders. I tried using Search-Mailbox , but received: The term 'Search-Mailbox' is not recognized as the name of a cmdlet... I understand that Search-Mailbox is deprecated in Exchange Online. Also, the Content search is not very helpful.Solved405Views0likes3CommentsDoes Exchange Online have an internal search Index for people ?
Hello everyone, I'm managing users with Office 365 E3 licences. We have an hybrid Exchange Online / Exchange On-Premise architecture. My problem is the following: After I create an user with E3 licence, and after AAD Synchronisation between Azure / AD, the user is created on Azure but also the email mailbox (Exchange Online). But within the "To" input, through the Autocomplete suggestions, this user cannot be found, neither with Outlook Desktop Client nor with OWA Outlook (Web version of Otlook), even several hours later of the creation. I can use the mailbox (can login to OWA Outlook), can send / receive. So the mailbox is created correctly. I can connect to Exchange-Online via PowerShell and get all informations for the target mailbox (like others) with: Get-Recipient -Identity "email address removed for privacy reasons" And also via Get-Recipient -Anr "elon" (this gives me "Elon, Musk" as a suggestion through PowerShell). But why the autocomplete cannot suggest me this user ? Through the GAL (Global Address List) the user is visible (when I click on "To" button within Outlook Desktop Client -> Popup showing the Global Address List). But it's not suggested automatically, like others (old users). I made several hours of searches but I do not found any concluant result. My only question is: does Exchange Online infrastructure have an internal Search Index for People ? And if so, how often it's updated to include newly added users to the tenant? On what is based the autosuggestions within the inputs "To" / "CC" / "CCI". In my case (at least), the search for autosuggestions cannot be based on Global Address List / Offline Address Book from our On-Premise Exchange server, because EVEN the Web based OWA Outlook cannot find the newly created user! Thank you in advance for your precious help! Best Regards, Adam J.59Views0likes0Comments
