Hybrid Update Agent download fails
Hi there, last Friday I was successfully able to execute the HCW with the full classic deployment. As we had some sharing issues we tried the full modern as well. But we were able to execute the HCW and finish it all the time. This morning there was an update for the HCW and suddenly we had issues with the part Hybrid Update Agent download which always mentions "Content Not Found" We tried this several times throughout the day, but unfortunately the error is still the same. Is there a general issue with the location of the HybridAgent file since the HCW has been updated? Kind regards
Exchange 2016 with Hybrid Configuration
We have Exchange Server 2016 configured in a hybrid environment. We encountered an error when one of our administrators attempted to install a cumulative update that was the same version as the one already installed. After that, we were unable to access OWA, ECP, or the Exchange Management Shell. Exchange Server 2016 CU23 (2022H1) 15.1.2507.6
new Exchange Installation Autodiscover
Hi I have had a lab environment and suspended this to get experience with a new setup. Old setup had a ADFS server in place. New lab setup is based on Windows Server 2025, 1 DC, 1 Exchange server SE. Installation is ok. Client is a Windows 11 machine with Outlook 2019. DC is synching to EntraID. All based on German language. GPO for autodiscover is set. As well the DNS records. Post installation is the part where I am have an issue at. At least in the part of the autodiscover. Adding the primary mail address is always leading in pointing to the company authentification page adfs.xy.com which was in the old lab in place. I cant see any DNS entry neither on my external DNS provider nor internal (brand new setup) and have no clou where to search further. Wensearch did also not lead me to any solution. And a workaround to disable autodiscover is not my goal. Therefore I am happy to get any idea where to look at to get read of the adfs link. Appreciate your support. THY mameFinding Unused Proxy Addresses for Exchange Online Mail-Enabled Objects
A request came in about how to find unused proxy addresses for Exchange Online mail-enabled objects. There's no out-of-the-box report available for proxy address usage, but we can solve the problem by using a PowerShell script to download historical message trace data to check every proxy address for all mailboxes against. The question then is what to do with the unused proxy addresses? https://practical365.com/find-unused-proxy-addresses/
AuthServer in Exchange Online
The result of Get-AuthServer is different between on-prem and EXO. The list of objects from EXO get-authserver includes some "IssuerIdentifiers" that include a "{tenantid}" pattern. Was this supposed to be expanded by a script, or by HCW? (HCW has never run to completion without exceptions.) There seems to be no documentation about this: no list of default entries, no documentation on the expected form, few mentions of the use of Set-AuthServer/New-AuthServer, and the options don't match the properties.
Exchange 2019 AvailableNewMailboxSpace
Hello! Colleagues, have you encountered a situation where Exchange 2019 does not provide accurate information about the amount of free space in databases (AvailableNewMailboxSpace) via EMS? Using this command: Get-MailboxDatabase -Status | Sort-Object Name | Select-Object Name,@{Name=‘DB Size (GB)’; Expression={[math]::Round($_.DatabaseSize.ToGb(),2)}},@{Name=‘Free Space (GB)’;Expression={[math]::Round($_.AvailableNewMailboxSpace.ToGb(),2)}} | Format-Table -AutoSize Exchange 2016 displays the information correctly, but 2019 does not display it correctly in gigabytes or the numbers are unclear. Do you know of another way? Thank you!M365 Exchange - delete Calendar entries
Maybe a simple question, but struggle to find a way to do it I have a 365 admin account for our m365 tenent and running exchange online. A user has left and people struggle to cancel some meetings the person who has left has invited for. I hoped that I just could run some powershell script that silently would cancel all meetings that person has made. But struggle to find a way Anyone has some input on how to do this ? - and as mention I have exchange admin rights.
Dynamics 365 App for Outlook is not supported Cross Tenant
Hello, I am referring to the disclaimer here which clearly says that Dynamics 365 App for outlook is not supported when the excahange online is on a tenant separate from the Dynmics 365 Sales tenant. This seems to be true even after properly registering the Dynamics 365 as an application in the Azure Tenant of the Exchange Online instance and then configuring the profile etc. all correctly. It is mentioned that the incoming-outgoing emails and appt/contact/task sync will all work through server-side synchronization. But when will this be available for Dynamics 365 App for Outlook in cross-tenant scenario for customers ? As most customers prefer to have their exchange on a dedicated usually the corp hq tenant for better management and then all business apps in different separate tenants based on region/department/child companies ? Please also suggest if there are any workarounds. And kindly give me any pointers to other forums that will be more appropriate for this question, just in case…. Many Thanks https://learn.microsoft.com/en-us/power-platform/admin/connect-exchange-online-server-profile-oauthWhich ExchangeServerApp is the right one? How to tell?
From running HCW multiple times w/ various exceptions, we have a number of separate ExchangeServerApp instances in Entra. How can I definitively tell which one (or more) is the correct instance? I can't find any of the UUIDs in the Entra entries anywhere in the Exchange Server configuration. I can't run the ConfigureHybridExchangeApplication script because (from the error it gives) it doesn't handle the multiple app identifiers. I submitted feedback but haven't heard back from the CSS-Exchange people. Any guidance appreciated.
Room´s Notifications goes to deleted itens
Good morning I have the following problem when creating meetings via Outlook Rooms. When we create a meeting invite via a Room's calendar, after the other person has accepted/rejected the meeting, the notification goes directly to the deleted items in the Room's mailbox. If I do the same process with my account, the acceptance/rejection notification stays in my inbox. Is this a room-specific setting? Is it possible to change this behavior? Thank you
