Does 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.
Exchange database dismounted due to NTFS file extent limit reached – unexpected outage
Hi everyone, We experienced a serious outage on our Exchange 2016 server recently, and I wanted to share what we found during the root cause analysis – in case it helps someone else avoid the same scenario. Summary: After digging deep, we discovered that the issue was caused by the NTFS file system hitting its internal file extent limit on the .edb file. Once this threshold was reached, the database could no longer grow, and the system dismounted the database unexpectedly. No prior warning, just service interruption. Details: The .edb was around 1.2 TB in size. This isn’t a limit on database size itself — it’s about how fragmented the file is on disk. Once NTFS couldn’t track any more extents, the database stopped working. Microsoft doesn’t publish a clear fix for this; only scattered references to similar behavior in past cases. What we did: Created a fresh, clean database. Manually moved user mailboxes into the new DB. The old database couldn't be mounted anymore, so we brought the system live without historical mail – just to maintain continuity. We're now working on extracting data from the unmounted .edb using third-party tools. Looking for thoughts: Has anyone else hit the NTFS extent wall with Exchange? How do you monitor extent growth proactively? Did switching to ReFS solve this for you long-term? Open to any input or similar experiences – appreciate it in advance. Thanks!
OL client in-app link for getting OL for iOS or Android not working
Hello! Redirected to this forum from here: https://learn.microsoft.com/en-us/answers/questions/5617563/ol-desktop-link-broken-file-get-ol-app-for-ios-and See error description and attempt to solve it by following the link. For some reason, Windows clients in our organization can not follow the Outlook desktop client in-app link for getting Outlook for iOS or Android. (hybrid, no mailboxes in MS-cloud, only on prem) The link for getting the Outlook app for iOS and Android under File when logged into Outlook app does not seem to work. Clicking on it seems to send user to the URL: go.microsoft.com/fwlink/?LinkId=2112779 but quickly redirects and ends up with https://w2.outlook.com/l/mobile?WT.mc_id=Backstage**Win32**All**Hyperlink** https://learn-attachment.microsoft.com/api/attachments/cb7d456f-ac6e-4566-a4ef-ffa912500423?platform=QnAhttps://learn-attachment.microsoft.com/api/attachments/cb7d456f-ac6e-4566-a4ef-ffa912500423?platform=QnA We haven't been able to figure out why, but since the same two different accounts mentioned in the thread above works on a private device on a private home network, is seems like something in our environment is the cause.Outlook Client unable to search on Server.

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
Stop ASP.NET SMTP Emails from Appearing in Office 365 Sent Items Without Affecting Manual Sends
We are sending Emails to our clients through an ASP.NET application using the SMTP protocol and using an O365 Account (email address removed for privacy reasons). The problem is that every time a mail (reset password, otp, campaigns, etc) is sent from asp.net application, a copy of that mail is created in the "Sent Items" of the Support mailbox. This is not needed and it is quickly filling our Support mailbox. How to stop this? Is there any setting in the Exchange Server? Please note that the Support mailbox is also used by our company support representative to send resolutions to customers using O365 Outlook Web Access. The mails send by the representative are very much needed in the sent items. It's only the ASP.NET-sent mails that we want to prevent in the "Sent Items".Exchange synch/profile issue
Dear community, I need help to solve a problem. 1.) I'm using Outlook classic 2016 2.) I need two mail accounts in outlook a.) my gmail account - all good with that one b.) my AWS Workmail account 3.) all used to work fine till I had another problem with teams integration into my calendar which I tried to fix without success. After a while I thought, that when I setup outlook from scratch that this could solve the problem - but it got worse. 4.) when I started the newly installed outlook, I can load my gmail account, and when I add my AWS Workmail account, I get the message that the account was successfully added and need to restart Outlook. 5.) After the restart I get the two messages: - The name cannot be matched to a name in the address list. - Cannot start Microsoft Outlook. Cannot open the Outlook window. The set of folders cannot be opened. An unexpected error has occurred. 6.) so the AWS Workmail is not loaded. I also tried to add the account manually in all different ways but without success. The integration of the AWS mail account on my Android Outlook works perfectly fine. I dont know where the problem is and tried to get answers from AI and Microsoft Support without success. Anyone has an idea? Many thanks, Rob
