Problems after upgrade to CU14
Hi, I'm in the process of migrating from Exchange 2013 CU23 to Exchange 2019. I installed Exchange 2019 CU13 on Win2022 Server, in coexistence with our 2013 and everything was looking good. Before starting with the testing to route emails through 2019, I checked that CU14 was released recently, so I download/install the CU14 in upgrade mode (with the no EP flag) to have the last build, and now I'm having problems with virtual directories, mailboxes, and so ON. Already run the healtchecker powershell scripts and nothing out of the ordinary. Some of the problems I'm having: 1. When I clic on the 'authentication' tab in any Virtual Directory (ECP, OWA, EWS) I got this error: "The task wasn't able to connect to IIS on the server <FQDN>. Make sure that the server exists and can be reached from this computer: The RPC server is unavailable." The other tabs don't throw me any errors, but almost all options are greyed-out. 2. In SERVERS > DATABASES, when entering the properties of any Database that are on the new EX2019, I got this error: 'Exchange can't connect to the Information Store service on server <FQDN>. Make sure that the service is running and that there is network connectivity to the server.' I cannot create a new Database neither and the status of the currents 2019 Mailbox databases says Uknown and BadCopyCount = 1. 3. SERVERS > CERTIFICATES: Cannot see any Cert here for the EX2019. The error I get: "Cannot connect to the remote procedure call service on the server named <servername>. Verify that a valid computer name was used and the Microsoft Exchange Service Host service is started." Already check: - Binding of the Certificate 'Microsoft Exchange 'on the BackEnd and our Public Certificate on the Frontend Server. - All Exchange Services are up and running. - Restart of IIS. It appears that is something with permissions and/or with IIS that breakdown after the installation, but still don't know what it is. Al things related to the 2013 environment appears to be normal and functioning. according. Something I noticed, on the Certificate error it says the name of the server, and in the other errors, it says the FQDN of the server. Please guide me here, what could be the problem and what to check/confirm. Thanks in advance.
Missing Teams Contacts after Migration
Hello, We are currently migrating mailboxes from exchange 2019 to exchange online. The migration works absolute flawless. Now we have some employees complaining about missing teams contacts that were previously created in Teams only. The MS support told me that this is a teams limitation and the local contacts are gone. I know about unified contacts, thats contacts are synced now between outlook and teams and newly created contacts are stored in exchange online mailbox. But whatabout the old contacts ?? cant believe that theres no workaround to keep this contacts. Do you know something about this ? Rene
How to extract domain of the original link from a SafeLink
I'm trying to extract the original domain from the links that are warped by Microsoft SafeLinks I use the Nager.publicsuffix library in C# to parse domains, but with SafeLink's it only returns the SafeLink domain instead of the real one Example: https://ind01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fstspg.io%2Fn504fyn3g38x... https://nam.safelink.emails.azure.net/redirect/?destination=https%3A%2F%2Fentra.microsoft.com%2Fdemodomain.cf%23blade... I've tried writing custom logic for SafeLink pattern, but Microsoft seems to use different formats, so it's not reliable Question: What's the best way in C# to reliably detect and unwrap these SafeLink's (or other tracking URLs) so I can extract the original domain before passing it to Nager.PublicSuffixIssue with Distribution Groups Members
Hello Please i need your help on this issue. Issue with Distribution Groups Members. I created Manually Dynamic Distribution Group and added Users with Exchange Mailbox option but its added all the active licenced users and shared mailboxes and unlicenced users also. I only want Licenced users only in that group where E3 Licenced are assigned and users are active. But all users are added in that group instead of Licenced active users. I need only automatically add active users who has Office 365 Licence. I do not require any shared mailbox users I do not require non-active users NOTE: I do not want to create the users through PowerShell. So please is there a solution for GUI only
Meeting rooms - end of synchronization with AD
Hi all, We have a hybrid environment, and the meeting rooms are "physically" in Exchange Online—I can no longer see them on the on-premises Exchange server. However, they are still synchronizing from AD. What do I need to do to ensure that the meeting rooms are completely in Exchange Online and do not synchronize from AD? So that the "point of truth" is in Exchange Online? Thank you for your tips.
Exchange 2016 to SE and Exchange Online questions
Hi, We're currently in the process of migrating from Exchange 2016 to Exchange Subscription Edition (SE), along with moving a portion of our mailboxes to Exchange Online. We have approximately 3,000 mailboxes, and around 2,000 of those will eventually end up in Exchange Online—for various reasons (don’t ask why…). I have a few questions I'd like to clarify and hope you can assist: Exchange On-Premises Questions: If a user mailbox is moved to Exchange SE, can they still access shared or user mailboxes that remain on Exchange 2016? Do we need to migrate them in the same batch to preserve access/permissions? (should't be an issue in the same Exchange Org right?) If a shared mailbox is migrated to Exchange SE while the user mailbox remains on Exchange 2016, will access still work? Do we need to point the Hardware Load Balancer (HLB) to the new Exchange SE servers before mailbox moves to allow proper client connectivity and proxying back to Exchange 2016? Or is it okay to keep the HLB pointed to the Exchange 2016 servers until all migrations are complete and then switch it over? Proxy upwards from Exchange 2016 to Exchange SE? What’s the best practice here? Pros/cons? Exchange Online Questions: If we want all outbound mail to go through the on-prem Exchange environment—even for Exchange Online mailboxes—is this configured via the Hybrid Configuration Wizard (HCW)? Is the Litigation Hold status preserved when migrating a mailbox to Exchange Online? Can a mailbox hosted in Exchange Online access a shared mailbox still residing on-prem? (Should't be an issue right?) Can an on-prem mailbox access a shared mailbox that has been migrated to Exchange Online? For mailboxes with Full Access or Send As permissions (e.g. user mailboxes tied to shared mailboxes), do they need to be migrated together in the same batch to retain functionality? We’ll be using native Microsoft migration tools (no 3rd-party solutions). If I recall correctly, separate migrations will still allow Full Access?!?, but Send As may not work properly unless migrated together. Is that still accurate?Exchange 2016 and deffer delivery
Hi! Is it possible to configure delay of outgoing sending messages for user mailbox, like outlook's deffered delivery? I couldn't find such an option in mailflow-rules, as deepseek says "New-TransportRule -Name "DelaySendForUser" -SenderAddressEquals "email address removed for privacy reasons" -DeferMessageMinutes 2 -Enabled $true" - it doesn't work:))How to consistently differentiate Microsoft service notification emails from normal user emails?
I receive a large number of notification mails from Microsoft services (SharePoint, Teams, etc.) and they clutter my mailbox. I’ve tried: Inbox rules filtering by sender (e.g., email address removed for privacy reasons) → doesn’t work since Microsoft uses many changing domains. Filtering by Microsoft IP ranges → some internal org mails also get caught. Filtering by domains from Microsoft endpoint list → works, but the list updates monthly, so not reliable. Question: Is there a consistent way (e.g., via Internet message headers or any other property) to reliably identify Microsoft-generated notification emails vs normal user emails?
HCW fails to download
Erst einmal Entschuldige mich mich falls ich diese Frage im falschen Kanal stelle Hallo versuche gerade mit dem "Programm" Microsoft.Online.CSE.Hybrid.Client.application die HYbrid Stellung zu realisieren komme aber nicht weiter . Das Programm startet einwandfrei. Die Datei Microsoft.Online.CSE.Hybrid.Client.exe.manifest wird aber nicht heruntergeladen In der Firewall kann ich keinen Blockierten traffic sehen. Meldung die Anwendung konnte nicht dedownloaded werden. Erforderliche Dateien fehlen in der Anwendung. Wenden Sie sich an den Hersteller der Anwendung OS Server 2012R2 Software Firewall ist aus Kein Antivirenprogramm aktiv Falls jemand ähnliche Probleme hatte und die lösen konnte wäre ich sehr dankbar über Hinweise wie das geschafft wurde. Der Support von Microsoft war nicht sehr hilfreich Ticket ist aber noch offen. Die Aktivierung von C:\HCW\Microsoft.Online.CSE.Hybrid.Client.application führte zu einer Ausnahme. Folgende Fehlermeldungen wurden entdeckt: + 'file:///C:/HCW/Application Files/Microsoft.Online.CSE.Hybrid.Client_17_1_2714_0/Microsoft.Online.CSE.Hybrid.Client.exe.manifest' konnte nicht gedownloadet werden. + Ein Teil des Pfades "C:\HCW\Application Files\Microsoft.Online.CSE.Hybrid.Client_17_1_2714_0\Microsoft.Online.CSE.Hybrid.Client.exe.manifest" konnte nicht gefunden werden.
