Validate Guest/Member users for accounts created before 2014
Old exchange accounts that were created before 2014-2015 don't have userType field. When we query such users their userType returns null: https://graph.microsoft.com/v1.0/users/xxx?$select=createdDateTime,userType How do we differ in such case between Guest and Member accounts?
Issue with Distribution Groups Members
Hello Please i need your help on this issue. Issue with Distribution Groups Members. I created Manually Dynamic Distribution Group and added Users with Exchange Mailbox option but its added all the active licenced users and shared mailboxes and unlicenced users also. I only want Licenced users only in that group where E3 Licenced are assigned and users are active. But all users are added in that group instead of Licenced active users. I need only automatically add active users who has Office 365 Licence. I do not require any shared mailbox users I do not require non-active users NOTE: I do not want to create the users through PowerShell. So please is there a solution for GUI onlyHow to extract domain of the original link from a SafeLink
I'm trying to extract the original domain from the links that are warped by Microsoft SafeLinks I use the Nager.publicsuffix library in C# to parse domains, but with SafeLink's it only returns the SafeLink domain instead of the real one Example: https://ind01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fstspg.io%2Fn504fyn3g38x... https://nam.safelink.emails.azure.net/redirect/?destination=https%3A%2F%2Fentra.microsoft.com%2Fdemodomain.cf%23blade... I've tried writing custom logic for SafeLink pattern, but Microsoft seems to use different formats, so it's not reliable Question: What's the best way in C# to reliably detect and unwrap these SafeLink's (or other tracking URLs) so I can extract the original domain before passing it to Nager.PublicSuffixHow to consistently differentiate Microsoft service notification emails from normal user emails?
I receive a large number of notification mails from Microsoft services (SharePoint, Teams, etc.) and they clutter my mailbox. I’ve tried: Inbox rules filtering by sender (e.g., email address removed for privacy reasons) → doesn’t work since Microsoft uses many changing domains. Filtering by Microsoft IP ranges → some internal org mails also get caught. Filtering by domains from Microsoft endpoint list → works, but the list updates monthly, so not reliable. Question: Is there a consistent way (e.g., via Internet message headers or any other property) to reliably identify Microsoft-generated notification emails vs normal user emails?Missing Teams Contacts after Migration
Hello, We are currently migrating mailboxes from exchange 2019 to exchange online. The migration works absolute flawless. Now we have some employees complaining about missing teams contacts that were previously created in Teams only. The MS support told me that this is a teams limitation and the local contacts are gone. I know about unified contacts, thats contacts are synced now between outlook and teams and newly created contacts are stored in exchange online mailbox. But whatabout the old contacts ?? cant believe that theres no workaround to keep this contacts. Do you know something about this ? Rene
Which 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.
Licensing question: Exchange Server SE for CSP M365 E3/E5 customers without Extended Use Rights
Does anyone have any information on licensing the new Exchange Server SE for customers who have M365/O365 E3/E5 purchased via CSP but do not have Extended Use Rights (i.e., no EA/EAS -> no on-prem Office server licenses included)? Specifically: Is it enough to license Exchange Server SE per node only, or Do customers also need to purchase Exchange Server CALs per user (even if they already have M365 E3/E5)? I’ve spoken with multiple licensing distributors and a Microsoft partner contact, but I still haven’t been able to get a definitive answer. According to a comment from Jeremy Carlson and Microsoft’s licensing documentation, certain licenses appear to include "CAL-equivalency rights". Can anyone here confirm whether these CAL-equivalency rights cover access to Exchange Server SE in the CSP E3/E5 (no Extended Use Rights) scenario? licensing reference: https://www.microsoft.com/licensing/terms/product/CALandMLEquivalencyLicenses/MCA#clause-2165-h3-1

Thank you.Domain not routing mail or logins correctly after tenant transfer
Hello Please i need your help on this issue. Domain not routing mail or logins correctly after tenant transfer. I recently removed the domain sustainable.XXXX from an old Microsoft 365 tenant (based in Chile) and added it as the default domain in my new tenant (based in Spain). The domain is showing as Authoritative and in a healthy state in the Microsoft 365 Admin Center. DNS records (MX, SPF, CNAME autodiscover) are all configured correctly and propagate globally (checked with multiple DNS tools). However, I am still experiencing two critical issues: Authentication / Login Redirect. When I try to log in with rphilippe@ sustainable.XXXX in Office apps (desktop and mobile), the login is automatically redirected to the old Chile tenant (…onmicrosoft.com), which no longer has my domain or licenses. This prevents me from signing into Office apps with my licensed email address in the new Spain tenant. Mail Flow – No Inbound Delivery I can send outbound emails from rphilippe@ sustainable.XXX without problems. But inbound emails from Gmail/Yahoo do not appear in Message Trace in Exchange Online. This indicates that messages are not reaching my new tenant at all, despite correct MX records. Steps already taken: Removed domain completely from old tenant. Verified domain ownership in new tenant. Configured all required DNS records at my registrar (Wix). Waited more than X hours since DNS propagation completed (global MX records confirmed). Tested with Message Trace and Quarantine: no trace of inbound messages. Request: Please verify and force a refresh of Home Realm Discovery (HRD) and Exchange Online domain routing for sustainable.XXX, to ensure: Authentication requests for @ sustainable.XXXX point to the correct (Spain) tenant. Inbound email is routed correctly to the new tenant. This appears to be an internal Microsoft propagation/cache issue, not a DNS or local client issue.I need help with migration
Hello I need to migrate our account to a wider business due to a merger. In general, I need to change the domain name while keeping my email history without losing any data. On top, I need to ensure after that after the change the extensions of our emails from (i.e @ abc.com to @ abd.com) to have access to the emails which are still being sent to @ abc.com, for example being automatically forwarded to the new email addresses.
