- Recipients experience issues receiving mail after their mailbox is migrated.
- Senders receive a non-delivery report (NDR) that contains error 5.1.1 or error 5.1.4 when they send mail.
|Environment||Attribute||Description of the correct value||How to check the value *|
|Source||Primary Simple Mail Transfer Protocol (SMTP) address||The primary SMTP address should match the primary SMTP address in the managed environment.||The managed primary SMTP address is listed in the address book and in the Active Directory schema of the managed environment. Review the source primary SMTP address in the source Active Directory schema.|
|Source||Target address||The source object should have a target address that has a suffix of mgd.<CustomerDomain>.com and a matching secondary SMTP address in the managed domain. No target address should exist on the managed object.||The managed secondary SMTP address will be listed in the address book and in the Active Directory schema of the managed environment. Review the source target address in the source Active Directoryschema.|
|Source||No value is listed for the HomeMDB attribute or for the HomeMTA attribute.||The source object should not have an Exchange server that is listed in the HomeMDB attribute or the HomeMTA attribute. These values should exist only in the managed environment.||The managed Exchange mailbox information is listed in the Active Directory schema. No value should be listed in the source Active Directory schema.|
|If no mail forwarding is desired, the forwarding address should be cleared. If mail forwarding is desired, the delivertomailboxandforward attribute should be set to $true so that mail is delivered to both the original and forwarding addresses.||These values can be viewed in PowerShell by running the get-mailbox cmdlet.|

Troubleshoot specific NDRsIf a sender receives an NDR when they try to send mail to a mailbox, it is important to collect as much information about the NDR as you can or to request a copy of the NDR message. This section contains information about how to troubleshoot specific NDR messages.
- 5.1.1 NDR "unknown user/recipient address not found"
This NDR occurs if the address that the sender used does not exist in either the source environment or the destination environment.
To resolve this issue, confirm the configuration state of the source and destination primary SMTP addresses and email address list of each object. Specifically, make sure that the target address of the source object is set to point to the managed environment (for example, @mgd.<CustomerDomain>). Additionally, make sure that the target address of the source object exists in the proxy addresses of the managed object.
- 5.1.4 NDR "ambiguous address"
This NDR occurs if there is another object in either the source forest or the destination forest that has the same SMTP address.
To resolve this issue, search the source forest and destination forest for that SMTP address. If multiple objects are found, cross reference the display name, msCustomerDNString, mailnickname, and primarysmtpaddress attributes to determine whether they are the same user. If they are the same user, contact Microsoft Support, because this may indicate a migration issue. If they are not the same user, confirm that there are no duplicate users in the source environment.
