How to know if Exchange oAuth Metadata is refresh
Hi, I have an environment with Exchange 2013 hybrid coexistence with Exchange 2019 now. oAuth is enabled. I am suspecting the current environment, servers won't refresh the oAuth Metadata themselves. Is there any logs I can trace that? What event ID indicate the metadata is updated?
Supported / recommended .Net versions Exchange SE on Windows Server 2019
I’m reading up on the Exchange SE upgrade, but there’s something I don’t understand. We are currently running Exchange 2019 CU15 on a Windows Server 2019 server (desktop experience). My initial plan is to perform an in-place upgrade from Exchange 2019 CU15 to Exchange SE, while remaining on Windows Server 2019 for the time being. From what I’ve read, this should be possible: https://techcommunity.microsoft.com/blog/exchange/why-%E2%80%9Cin-place-upgrade%E2%80%9D-from-exchange-2019-to-exchange-se-is-low-risk/4410173 https://learn.microsoft.com/en-us/answers/questions/2182463/upgrade-exchange-2019-to-exchange-se According to the supportability matrix, this should also be supported: https://learn.microsoft.com/en-us/exchange/plan-and-deploy/supportability-matrix Exchange Server SE is supported on Windows Server 2019. What I don’t understand is the table for .NET Framework support. It seems like Windows Server 2019 is missing for Exchange Server SE in that table, just like Exchange Server 2019 CU15 on Windows Server 2019 with its corresponding .NET version. https://learn.microsoft.com/en-us/exchange/plan-and-deploy/supportability-matrix?view=exchserver-2019#additional-requirements-and-information Does anyone have an explanation for this? I’d love to hear it!
How to Delete a Composing Email Attachment via Outlook Add-in?
Context: Server: Exchange Server 2019 on premise Client: OWA Category: Outlook Add-in Office JS API Set: Supported up to 1.5 only Problem Details: Delete an attachment added manually or through EWS API to an email item. Limitations: 1. Limitation of makeEWSRequestAsync() Office JS method: The makeEWSRequestAsync method in Office.js does not support the DeleteAttachment SOAP operation, which is required from outlook add in. -> Attempted Workaround - Using fetch with EWS SOAP Request: I tried invoking the DeleteAttachment operation via a fetch call to the EWS endpoint. However, EWS response states "requested web method is not allowed for this application". 2. OWA Limitation: As OWA in this environment only supports Office.js up to version 1.5, the modern attachment Office JS APIs and Graph APIs are not an option. Question: In an Exchange On-Premises scenario, how can I programmatically delete attachments via my add-in? Specifically, is there a recommended approach to obtain a valid token for EWS requests, or any supported alternative to perform DeleteAttachment? Any way to convert EWS attachment ID to Office JS attachment UUID? Additional Notes: I am aware that Exchange Online supports more modern APIs (Graph/REST), but my current deployment is strictly Exchange On-Premises. The add-in works well for reading attachments and other operations, except for deletion. Any guidance or recommendations would be highly appreciated! Thank you in advance.

Arbitration Mailboxes not available
I have an environment with an Exchange 2013 (15.00.1497.048) and an Exchange 2019 CU14 server installed. The new 2019 server appears to be fully operational with the exception of the system mailboxes, which means I cannot migrate the mailboxes off the 2013 server. What I have tried to resolve this issue: Re-run /PrepareAD - This did create the AD accounts; however, the system mailboxes were not created and when attempting to enable them getting the following error: "The user's Active Directory account must be logon-disabled for linked, shared, or resource mailbox." Checked for disabled or soft-deleted mailboxes - none that match the GUIDs for the system mailboxes Deleted the system accounts from Active Directory and re-ran /PrepareAD. It ran successfully and created the AD accounts; however, still getting the same error when attempting to enable the mailboxes. Looking for any insight into how to resolve this issue.554 5.3.4 Content conversion limit(s) exceeded
Could not send mail from PowerBI to local mailbox using SMTP receive connector. There is EventID DELIVERFAIL: "STOREDRV.Deliver.Exception:ConversionFailedException; Failed to process message due to a permanent exception with message The content conversion limit has been exceeded. ConversionFailedException: The content conversion limit has been exceeded. [Stage: PromoteCreateReplay]'" in Transport log. How/where could I check/set the content conversion limit? Is there some other log, where I can find detailed information about this? Message size is 1.3MB, maximum message size in connector is 20MB Exchange 2019 CU 14 Thanks.Defender: Exploit of HAFNIUM on newest MS Exchange Version?
Hi all, I'm running an exchange on Windows Server 2022, on Exchange Build 15.2.1544.14 (Nov 2024 CU) I've just received an MS Defender EDR High Incident of possible infection of the exchange server. I've checked the Version and Patchmanagement, everything looks fine, even Defender says in the device page "missing kbs" that there is nothing to update. Can I ignore that? I'd say yes, but why would defender create a high incident for that? BR Schnittlauch
How to repair a corrupted Public Folder (on-prem)
Hello guys, Hope all is well. In our Exchange 2019 environment we use Public Folders extensively. Everything seems ok except one of folders that looks corrupted. I can execute commands Get-PublicFolder / Set-PublicFolder against it, I can get its items statistics (Get-PublicFolderItemStatistics) and have access to items through Outlook. But commands Get-PublicFolderStatistics, Get-PublicFolderClientPermission return the same error: The security principal specified is already on the permission set. + CategoryInfo : NotSpecified: (:) [Get-PublicFolderStatistics], CorruptDataException + FullyQualifiedErrorId : [Server=E7,RequestId=b2f89187-878f-4cab-b05f-fcdaa7d82c0d,TimeStamp=2/17/2025 3:19:42 PM] [FailureCategory=Cmdlet-CorruptDataException] B960021F,Microsoft.Exchange.Manag ement.MapiTasks.GetPublicFolderStatistics I tried to repair the corresponding public folder mailbox (New-MailboxRepairRequest) but none of my requests found errors. I moved the public folder content to a different public folder mailbox, no success. Any ideas how to fix the issue? My guess is that ACL list of the public folder is corrupted. Regards, Dmitry Horushin
Two Exchange servers in one domain
Hello everybody, I want ask you, because I can’t find how “Exchange magic” works. I have two seperate Exchange DAG clusters in one domain, with different DNS records and different Virtual Directories URLs. Servers are on two physically diferent locations, but we create a direct connection between two locations for migration mailboxes in near future. We notice sometimes clients from old enviroment can connect through new enviroment and access to mailboxes on old servers. How is it possible? What communication ongoing between old and new Exchange enviroments? Can somebody explain me specifically? Thank you very much for answer to this mystery.
