Autoreseed, now what?
Have had a disk failure in a four server Exchange SE DAG with autoreseed enabled. New disk inserted, but now what? What I can google and AI myself to is something like this: Bring the new disk online Remove the broken mount point by deleting the mount point folder that does not lead anywhere Create a New Simple Volume and mount it in an empty NTFS folder Format it as per our standard, ReFS 64K and label to our standard (same as the old one) Does the experts agree that this is all there is to it? Many thanks!SolvedMartenTJan 15, 2026Copper Contributor44Views1like6CommentsUpgrading to Exchange SE
Hi, I currently have Exchange 2019 and need to upgrade to SE. When attempting an upgrade the process didn't appear as expected. Articles I've read basically said the process should be the same as a regular CU upgrade. When I run setup from the ExchangeServerSE-x64 iso, I get an Add Server Role window, instead of the expected upgrade method. The window presents 3 Roles, 2 are ticked, and they're all greyed out. The Next button has no function. I have Standard Edition 15.2 2562.17 (CU15). When checking my build number online, it is listed as the SE version, released July 1st, 2025. When I run Get-ExchangeServer, the Edition = Standard. Should it not say Subscription, or maybe SE? How do I verify my installation is actually SE? ThanksSolvedSteveJDJan 08, 2026Copper Contributor129Views1like3Comments
Need 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.SolvedsakhareashwinDec 05, 2025Copper Contributor190Views0likes3Comments
Help please! Exchange report questions
Hello! I’m hoping someone can help clarify a few things about a deletion report I received. The report shows hard and soft deletes, but it seems to be missing information about moves and restores. I’m trying to understand the following: 1. **Hard Deletes:** * When something is hard deleted, does it go to the Purge folder, and is it still recoverable from there? * Is a “hard delete” simply what happens when someone empties their Deleted Items folder? * Can hard deletes happen accidentally? 2. **Limitations of the Report:** * Are there other reports that can show moves, restores, or whether an item is *currently* deleted? * My understanding is that this delete report only indicates that an item was deleted at some point, not its current status. Is that correct? 3. **Missing Message IDs:** * About half the entries in the report don’t include a message ID. Am I correct in assuming those items aren’t emails? If anyone is willing to chat or walk through this with me, I’d really appreciate it — I’m hoping to understand this report better. Any guidance or links to solid documentation would be truly appreciated. Thank you!SolvedDmvhelpneeded2Dec 03, 2025Copper Contributor86Views0likes3CommentsCould any one explain Exchange Server SE Licensing Model?
I have the following M365 licenses in my education tenant: Microsoft 365 A5 without Audio Conferencing (Student Use Benefit) As per my understanding, each user requires an A3/A5 license to access their mailbox on an Exchange Server (Exchange SE). Since A3/A5 licenses already include Exchange Online, do we still need to assign these licenses to each on-premises user, or is this only for compliance purposes? For example, if we have 100 on-premises users, must all 100 users be assigned A3/A5 licenses in Microsoft 365? Reference articles are below. Microsoft Product Terms Please correct me if I am wrong.Solved174Views0likes2CommentsHybrid 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 regardsSolvedwoelkiNov 17, 2025Iron Contributor2.3KViews4likes19Comments
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.SolvedkirkzNov 13, 2025Copper Contributor168Views0likes2Comments
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.

Hi everyone, We are planning to implement Microsoft Exchange Server on premises. Recently, we noticed that Exchange Server 2019 is approaching its end of life, and we don’t see any pricing information for the new Exchange Server Subscription Edition (SE). In this situation, what is the best approach? Do we need to purchase Exchange Server 2019 first and then upgrade to the SE version? If so, how does the pricing for the Subscription Edition work? Will there be an additional cost (for example, a yearly subscription) after upgrading? We would really appreciate any clarification or guidance on this matter. Thank youSolved465Views1like5Comments
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.SolvedGepardSep 27, 2025Copper Contributor126Views0likes2Comments
