What is the maximum number of recipients per message with Outlook 2010 and Exchange 2010 SP1? I have a user that needs to send an email with more than 5000 recipients.
Get-TransportConfig | select maxrecipientenvelopelimit -- returns 5000
Get-TransportServer -Identity TPServerName | select name,pickupdirectorymaxrecipientspermessage -- Returns 100
The "Maximum recipients" checkbox is "NOT" checked for the user.
