One of the errors that you may face during installation of exchange 2016 that may hanged on the step 7 of 14: Mailbox role: Transport service with the following error:
”
The following error was generated when “$error.Clear();
if ( ($server -eq $null) -and ($RoleIsDatacenter -ne $true) )
{
Update-RmsSharedIdentity -ServerName $RoleNetBIOSName
}
” was run: “Microsoft.Exchange.Data.DataValidationException: Database is mandatory on UserMailbox.
at Microsoft.Exchange.Data.Directory.ADDataSession.Save(ADObject instanceToSave, IEnumerable`1 properties, Boolean bypassValidation)
at Microsoft.Exchange.Data.Directory.Recipient.ADRecipientObjectSession.Save(ADRecipient instanceToSave, String callerFilePath, Int32 callerFileLine, String memberName)

Based on this error message, issue occurs because some of the arbitration mailboxes don’t have mailbox database associated with them.
We could run the following command to confirm it:
”
Get-Mailbox -Arbitration | ft Name, Database –Auto
”
From the output, we could find the mailboxes that don’t have mailbox database assigned. In ADUC, delete the AD accounts, then re-run AD prepare to recreate the accounts. Then re-run Exchange setup program and check issue persists.
