Exchange 2007 - We are having a sporadic problem with external mail being (or not being) delivered when sent to a distribution list. Sometimes the delivered/not delivered messages are sent within minutes of each other. Tracking the messages, I see that they are getting to our Exchange server. Sometimes the list is expanded correctly, sometimes Exchange says the list is empty. I can't find anything using web searches. Here are some excerpts from the tracking logs (both expanded/delivered and not expanded/not delivered): Not delivered:[PS] C:\temp>Get-ExchangeServer | where {$_.isHubTransportServer -eq $true -or $_.isMailboxServer -eq $true} | get-messagetrackinglog -MessageId:b5320744-8dfd-4904-bb27-cc5ce427d74b@yyy.xxx.com | select *Timestamp : 30-Mar-10 07:11:32 . . .MessageId : <b5320744-8dfd-4904-bb27-cc5ce427d74b@yyy.xxx.com>Recipients : {PAYROLLADMIN@xxx.COM}RecipientStatus : {}TotalBytes : 1039RecipientCount : 1 . . .MessageSubject : Tires Plus Checks & DD Statements are Ready. . . .

I did not get the delivered excerpts pasted correctly.

Have you checked PAYROLLADMIN@xxx.com for ambiguous resolution? If you do a get-recipient payrolladmin@xxx.com, do you get just one result?

When I go a get-recipient payrolladmin@xxx.com, I only see one entry: [PS] C:\temp>get-recipient payrolladmin@tiresplus.com Name RecipientType---- -------------Payroll Admin MailNonUniversalGroup [PS] C:\temp>get-recipient payrolladmin@xxx.com | select * Alias : PayrollAdminCity :Notes :Company :CountryOrRegion :PostalCode :CustomAttribute1 :CustomAttribute2 :CustomAttribute3 :CustomAttribute4 :CustomAttribute5 :CustomAttribute6 :CustomAttribute7 :CustomAttribute8 :CustomAttribute9 :CustomAttribute10 :CustomAttribute11 :CustomAttribute12 :CustomAttribute13 :CustomAttribute14 :CustomAttribute15 :Database :DatabaseName :Department :ManagedFolderMailboxPolicy :EmailAddresses : {MS:MORGANTIRE/CLEARWATER/PAYROLLADM, X400:C=US;A= ;P=MorganTire;O=Clearwater;S=PayrollAdmin;, SMTP:PayrollAdmin@xxx.com}ExpansionServer :ExternalEmailAddress :DisplayName : Payroll AdminFirstName :HiddenFromAddressListsEnabled : FalseEmailAddressPolicyEnabled : TrueLastName :ResourceType :ManagedBy :Manager :ActiveSyncMailboxPolicy :ActiveSyncMailboxPolicyIsDefaulted : FalseName : Payroll AdminOffice :ObjectCategory : mta.com/Configuration/Schema/GroupOrganizationalUnit : xxx.com/UsersPhone :PoliciesIncluded : {{A5E4686F-F32E-4838-9FC1-4F9E453AEBEF},{3B6813EC-CE89-42BA-9442-D87D4AA30DBC}, {0E6A474B-C799-4A72-B47F-F12B4EFF40C3},{26491CFC-9E50-4857-861B-0CB8DF22B5D7}}PoliciesExcluded : {}PrimarySmtpAddress : PayrollAdmin@xxx.comRecipientType : MailNonUniversalGroupRecipientTypeDetails : MailNonUniversalGroupSamAccountName : Payroll AdminServerLegacyDN :ServerName :StateOrProvince :StorageGroupName :Title :UMEnabled : FalseUMMailboxPolicy :HasActiveSyncDevicePartnership : FalseAddressListMembership : {Exc03-GAL, Default Global Address List, MTA, All Groups}ExchangeVersion : 0.0 (6.5.6500.0)DistinguishedName : CN=Payroll Admin,CN=Users,DC=xxx,DC=comIdentity : xxx.com/Users/Payroll AdminGuid : feb1f0ed-8a85-4809-be89-913d35fd7810ObjectClass : {top, group}WhenChanged : 23-Mar-10 11:22:08WhenCreated : 25-Feb-05 14:19:40OriginatingServer : tpcldc-02.xxx.comIsValid : True Thanks.

The group is not a universal group. There are two domains in the forest, a root domain (empty except for two domain controllers) and a child domain (users, servers, groups, contacts, etc. located in this child domain). Thanks.

I'd make that a Universal group, and see if the problem doesn't clear up.

If the GC that was used to expand the group was in the root domainthen the membership of the group isn't present in that GC if thegroup's scope is Global. This is why it's important to use theUniversal scope for mail-enabled groups.
