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
Problem with Teams and Exchange Integration
Hi everyone, My goal is to integrate Exchange Server (Exchange 2016 CU23) with Teams so that the Teams calendar can be used. I have set up Hybrid Configuration (Classic Full Hybrid) and completed the setup without any errors. I have also checked Entourage, and it shows that Exchange has been registered, but the Teams calendar is still not working. Check items: 1. Get-AuthServer 2. Get-IntraOrganizationConnector → Confirm the "Enabled" status. 3. Get-PartnerApplication → Confirm it's enabled. 4. External resolution of the Autodiscover and EWS virtual directories 5. Run Teams Exchange Integration → The only thing that works is "Verifying if the user's mailbox is discoverable by the Teams service," and everything else is fine.The user's mailbox is not discoverable by the Teams service. Please ask your administrators to verify the user has a mailbox and to confirm the connectivity between Teams and Exchange. Does anyone have any other ideas or suggestions to help me? Thanks!Policy for limiting external domains and allowing particular external receivers
Hi community, According to the guide https://learn.microsoft.com/en-us/defender-office-365/outbound-spam-policies-external-email-forwarding i have created the following rule for our test domain: Rule description Apply this rule if 'X-MS-Exchange-Inbox-Rules-Loop' header matches the following patterns: '.' Do the following Set audit severity level to 'Medium' and reject the message and include the explanation 'Delivery not authorized, message refused' with the status code: '5.7.1' Except if recipients's address domain portion belongs to any of these domains: 'xyz.com' Rule Idea is to block all external mail forwardings except the ones directed to the domain xyz.com. ______________________________________________ Another rule testing i performed: Apply this rule if Is sent to 'Outside the organization' and sender's address domain portion belongs to any of these domains: 'localdomain.com' Do the following Set audit severity level to 'Medium' and reject the message and include the explanation 'external forwarding is not allowed' with the status code: '5.7.1' Except if recipients's address domain portion belongs to any of these domains: 'xyz.com'. Unfortunately this is not working and if i create mailbox-based rules that forward to mails lets say to gmail and to xyz.com both , the mails get dropped with explanation: Reason: [{LED=250 2.1.5 RESOLVER.MSGTYPE.AF; handled AutoForward addressed to external recipient};{MSG=};{FQDN=};{IP=};{LRT=}] For both cases i made sure the auto forwarding is enabled under "anti spam" rules in the security admin center. I receive in the mail flow logs messaged dropped for a mail located in xyz.com and in gmail.com. The forwarding configured in outlook on a mail from localdomain.com is intended to auto forward messages to a mail address in gmail.com and in xyz.com, where they mails should arrive. I am wondering what would be the correct policy in order to being able to except particular ext domain/ext mailbox. Another approach i found is to disable the auto fwd globally and to enable it for particular users only, but unfortunately can not be limited to whom the mailbox can forward and this is not useful solution for us.

Migration Exchange 2016 to 2019 then SE
Hello, we replaced our old Exchange 2016 Server, to Exchange SE. After the update users notified me, that the search is taking long. We also have a lot of Errors in the Eventlog 3056 Scenario: UpdateMasterTable. The app master table could not be saved due to a conflict. Mailbox: x Error: Property conflict: DisplayName: 'BigFunnelPoiNotNeededReason', Resolvable: 'True', OriginalValue: 'Object is null', ClientValue: '2', ServerValue: '2' Property conflict: DisplayName: 'BigFunnelCorrelationId', Resolvable: 'True', OriginalValue: 'Object is null', ClientValue: 'Property: [{0b63e350-9ccc-11d0-bcdb-00805fccce04}:'BigFunnelCorrelationId'] BigFunnelCorrelationId, PropertyErrorCode: NotFound, PropertyErrorDescription: .', ServerValue: 'Property: [{0b63e350-9ccc-11d0-bcdb-00805fccce04}:'BigFunnelCorrelationId'] BigFunnelCorrelationId, PropertyErrorCode: NotFound, PropertyErrorDescription: .'

Property conflict: DisplayName: 'BigFunnelPOIUncompressed' Does somebody know how we can fix this problem? We find already that article that is similar but the workaround for the search (not the mirgration) doesnt work for us. We need Outlook cached. https://learn.microsoft.com/en-us/answers/questions/5508363/outlook-search-not-working-reliably-after-exchangeResolved: Hybrid Exchange Duplicate (Ghost) Mailbox Created After Assigning Exchange Online License
Summary During a hybrid Exchange migration, a user’s mailbox failed to migrate and mail flow broke due to a duplicate (ghost) mailbox automatically created in Exchange Online. Root Cause An Exchange Online Plan 2 license was mistakenly assigned to the user before migration. Azure AD sync then provisioned a cloud mailbox, even though the user already had an on-prem mailbox. This caused a hybrid mismatch — the user appeared in both environments, and migration failed with mailbox lookup errors. Resolution Steps Removed the Exchange Online Plan 2 license from the user account. Forced a DirSync (AAD Connect) synchronization. Verified that the mailbox existed only on-prem via PowerShell Get-Mailbox -Identity email address removed for privacy reasons | fl Name,RecipientTypeDetails,ExchangeGuid Confirmed the ghost mailbox was removed from Exchange Online. Re-ran migration batch successfully to Exchange Online. Verification Get-MailboxStatistics -Identity email address removed for privacy reasons | fl TotalItemSize,ItemCount,LastLogonTime Ensure only one mailbox object exists and mail flow routes correctly. Prevention Tips Don’t assign Exchange Online licenses to hybrid mailboxes before migration. Always verify mailbox location prior to assigning any license. Use PowerShell or EAC to check where the mailbox resides (on-prem vs. cloud). Environment Hybrid Exchange Deployment Exchange 2016 On-Premises Exchange Online (M365) Azure AD Connect This issue is not caused by connectors or mail flow settings, but by improper licensing before migration. Removing the license and resyncing resolves the ghost mailbox problem.
Arbitration mailbox
Issue: Arbitration Mailbox Issue During Exchange 2016 to 2019 Migration. Environment Overview: Mixed Exchange environment: Exchange 2016: EX1-16, EX2-16, DR1-16, DR2-16 Exchange 2019: EX1-19, EX2-19 Currently migrating mailboxes from Exchange 2016 to Exchange 2019. Issue Description: One system mailbox was found on an orphaned Exchange server and i removed manually. Post-removal, errors were observed related to the Migration and Federation arbitration mailboxes. Both mailboxes appeared under the User container but were not functioning correctly. A user-type mailbox with the display name “Migration” appeared. I thought this may cause issue with arbitration mailboxes. Remediation Steps Taken: Removed the user-type mailbox with the display name “Migration.” Manually removed both FederationMailbox and MigrationMailbox objects. Verified that the Exchange Trusted Subsystem has correct permissions on the Microsoft Exchange Security Objects (MSEO) container. Executed Setup.exe /PrepareAD, Its Re-created the Federation and Migration related users. Executed the following command to enable the arbitration mailbox: Enable-Mailbox -Identity <GUID-of-MigrationMailbox> -Arbitration (command executed successfully). Current Problem: Despite successful execution of the Enable-Mailbox command, the msExchRecipientTypeDetails attribute is not updating to the expected value. Current value: 8388608 and display name also looks wrong because its show “Microsoft Exchange Approval Assistant” seems to be incorrectly tied to the migration mailbox. This issue is preventing proper functionality of the migration mailbox, and as a result, the remaining mailboxes cannot be moved from Exchange 2016 to Exchange 2019.
