May be the Mailbox is deleted for that particular User, or ACCOUNT is disabled.

If you send the mail to a distribution list, check the members of the list in AD (do this recurently for all the DLs members of this DL) and, if present, remove it from there.

Furthermore, you can export the "altRecipient" field for your AD users and check if one of them has this unknown user set as alternate recipient.

In this case I would use adsiedit.msc to view the properties of the accountas the ADUC console might not show it.

Mentioned address for user "CN=Sudh S\0ADEL:0434641a-f5e2-4588-a8d8-c3bc1610e492,CN=Deleted Objects,DC=Development,DC=Group,DC=co,DC=uk" is deleted.

User Name: Sudh S

Also it seems to be moved to "Deleted Objects" OU of AD (could be part of User Accounts deletion process). But somehow it is not deleted completly from AD.

Use adsiedit.msc and try checking in mentioned OU. Or check in "LostAndFound" OU available in AD users and computers (viewable with Advanced Features Mode).

Yes that is also a possibility, I mean, in Outlook Client Frequenet Contacts , there might be an entry which is no longer exists.
Check it and clear it from there.

I have checked with multiple machine when sent to a group where all the groups where users are members for the whole company. This 1 mail bounces back to the sender.

There is not "Deleted Objects" of AD
And checked in Users and computers there is nothing inside "LostAndFound" OU

Have you been able to check the Alternate Recipient values of the DL members?

You could check to see how many users in your domain have alternate recipient by performing a custom search from the Active Directory Users and Computers console.

To do so, you could follow the next steps:
- from ADUC, right click on "Saved Queries" and choose New / Query
- fill the Name and Description fields of the Query
- click on "Define Query"
- in the Find drop down list choose "Custom Search"
- select the "Advanced" tab and paste the following LDAP query:
(&(&(&(& (mailnickname=*) (| (&(objectCategory=person)(objectClass=user)(|(homeMDB=*)(msExchHomeServerName=*))) )))(altRecipient=*)))
- click Ok on both the open windows

Your new query should return only the users in your domain that have something set as Alternate Recipient.
If it's just a few of them, you can check in parallel with ADSIEdit the value of the "altRecipient" field. Use ADSIEdit as with ADUC you might not see the corrupted value.
If you have many entries, I will show you how to perform an export with these users and check it afterwards.

(&(&(&(& (mailnickname=*) (| (&(objectCategory=person)(objectClass=user)(|(homeMDB=*)(msExchHomeServerName=*))) )))(altRecipient=*)))

Results an error

The query filter "(&(&(&(&(& (mailnickname=*) (| (&(objectCategory=person)(objectClass=user)(|(homeMDB=*)(msExchHomeServerName=*))) )))(altRecipient=*)))

I tested this in my environment and worked. Anyway, I checked manually the query and got a different version for this which is shorter:
 (& (mailnickname=*) (altRecipient=*) (| (objectCategory=person) (objectClass=user) (homeMDB=*) (msExchHomeServerName=*)))

Try this one please.

The shortest query would be:
 (& (mailnickname=*) (altRecipient=*))
