Exchange Availability service
I'm looking for clarification about the configuration on cross forest availability services explained in the followin article Configure the Availability service for cross-forest topologies | Microsoft Learn We have two forests with an exchange org on each of them. Forest A --- AD companyA.local ---SMTP companyA.com Forest B --- AD companyB.local ---SMTP companyB.com There's a bidirectional trusts between the two forests they need to be able to share the user's free/busy information between the two forest and the article seems to be what we need. It mentions to complete two steps Get-MailboxServer | Add-ADPermission -Accessrights Extendedright -Extendedrights "ms-Exch-EPI-Token-Serialization" -User "<Remote Forest Domain>\Exchange servers" Add-AvailabilityAddressSpace -Forestname ContosoForest.com -AccessMethod PerUserFB -UseServiceAccount $true given our setup am I correct if I do the following ? IN FOREST A Get-MailboxServer | Add-ADPermission -Accessrights Extendedright -Extendedrights "ms-Exch-EPI-Token-Serialization" -User "companyB\Exchange servers" Add-AvailabilityAddressSpace -Forestname CompanyB.com -AccessMethod PerUserFB -UseServiceAccount $true IN FOREST B Get-MailboxServer | Add-ADPermission -Accessrights Extendedright -Extendedrights "ms-Exch-EPI-Token-Serialization" -User "companyA\Exchange servers" Add-AvailabilityAddressSpace -Forestname CompanyA.com -AccessMethod PerUserFB -UseServiceAccount $true ThanksExpose ResourceDelegates in OWA Settings > Calendar > Resource Scheduling
Expose ResourceDelegates in OWA Settings > Calendar > Resource Scheduling · Community I'm posting this here in hopes of getting votes over at the feedback site. What I'm after as a solution is this: 1.) Room "Owners" be granted FullAccess (ideally with AutoMapping disabled). 2.) Room "Owners" open room mailboxes in OWA and manage both Calendar permissions, and Resource Scheduling options (a.k.a., Booking Options), entirely themselves. 3.) Admins are relieved of the burden of having to do all this work for Room "Owners" because some of the settings are hiding in PowerShell only. We're almost there in EXO's OWA options > Calendar > Resource Scheduling. We're just missing ResourceDelegates: I suppose additional checkboxes could also be added to cover off all the other settings available in Get-/Set-CalendarProcessing, but for me ResourceDelegates is the most vitally important one. In large orgs, the ability to truly hand off responsibility of these settings to a room owner will be a huge administrative overhead relief.Why Only Web-Based Outlook Clients Can Recall Encrypted Email
The new message recall facility has been around since 2022. Even after Microsoft revamped the feature in 2023, it’s still only possible to recall protected messages with OWA and the new Outlook. As it turns out, the reason is that a premium license is needed, and Outlook classic might need some new code to check for that license. In other news, Outlook mobile now supports message recall. https://office365itpros.com/2025/03/13/message-recall-protected/
Username change is not reflecting in Teams channel while adding him to channel
Hello all, Recently we changed name of one of our users and that change reflected everywhere well but for the user's manager when they try to add this user to a Teams channel, they are getting the old name. I had checked the users name in AD, Azure AD, M365 admin center, Exchange admin center Everywhere it seems to be updated but the user is reporting he is still seeing the old name for him only while adding this user to teams channel. Please suggest me what I need to check.
Unable to Add Exchange 2019 Email Account (Ionos) to Outlook (New) on Windows 11
Hello everyone, unfortunately, I am unable to add my Ionos (Exchange 2019) email account to the Outlook Windows app. On Windows 10, it was still possible to manually configure an Outlook account, which worked fine. However, on Windows 11, this option is no longer available, and I can’t revert to the previous version of Outlook either. When I try to add the account by selecting Microsoft 365 - Office 365, Exchange and entering my email address, I always get the error message: We couldn't find a work or school account with that email address. I have already contacted Ionos, but they couldn’t solve the issue either. They mentioned that Microsoft doesn’t allow setting up an Exchange account this way, even though the option is listed in the selection menu. Does anyone know how to fix that? Thank you very much!

Hello everyone! Some healthprobes on our Exchange 2016 Server have been reporting an unhealty state since the middle of February. OAB.Proxy, EWS.Proxy, Outlook.proxy and OutlookMapiHttp.Proxy. We have no mailboxes on the server, so its not critical, but I would still like to figure out what is going on. They all fail with "The remote server returned an error: (401) Unauthorized" and if I try to invoke the probe i see this in the response: It looks like the SSL validation is not happening. Is it normal for the probe to use localhost for this? When I run "Get-WebServicesVirtualDirectory" both internal and external virtual directry is set to our external url. Any insight is greatly appreciated!Outlook Search Folder for External Senders
I'm using the Outlook M365 desktop app on the current channel and Exchnage 2019 in Hybrid mode with Exchange Online. We route all mail inbound and outbound via Exchange Server. I'd like to create a search folder in Outlook to show only mails from external senders. The issue is the only criteria I can seem to create would rely on the From field and this seems to map to the SenderName on the MailItem object in Outlook. This is not the actual sender's mail address that would include the @domain etc but rather seems to be the senders name which is arbitrary from I can see e.g SomeSender. How to create a search folder based on the senders actual address?Exchange Online Restricts the Number of Dynamic Distribution Groups
Exchange Online is imposing a new tenant-wide limit of 3,000 Dynamic Distribution Groups. Few tenants might be affected, but the question might be asked why Microsoft is limiting DDGs at this point. Is it a cunning plan to prompt people to use dynamic Microsoft 365 groups instead? Or are some tenants abusing DDGs in weird and wonderful ways? Who knows, but the limit applies from early April 2025. https://office365itpros.com/2025/03/10/dynamic-distribution-groups-limit/
