Here is the setup: two forests, one with Exchange 2007 and Office 2010, the other with Office 365. I don't know if the problem I'm seeing is an Exchange, Outlook or Office 365 problem so I'm trying Exchange first ;-). I've created a moderated distribution group in Office 365. I've created a mail-enabled user in Office 365 that has an email address in the Exchange 2007 domain. When an email is sent to the distribution group from an address that isn't permitted, the "Approval requested" email is correctly sent to the email account on Exchange 2007. However, Outlook does not display the Approve/Reject options, which means that the moderator isn't able to do anything with the email! So, is this being caused by: Office 365 sending the email outside of its environmentExchange 2007 (which doesn't understand moderation)Outlook 2010 (for some strange reason that I can't really fathom) ? Any thoughts or do I need to repost this in a different forum? Thanks. Philip

Hi, To narrow down the causes, please have a test to change the mail-enabled user to another remote domain. If it works, the issue is related to the Exchange 2007 forest. If it still does not work, you may post the issue to Exchange online forum via: http://social.technet.microsoft.com/Forums/da-dk/onlineservicesexchange/threads Thanks, Simon Wu Exchange Forum Support Please remember to mark the replies as answers if they help and unmark them if they provide no help.

For my clarification, when you say "change the mail-enabled user to another remote domain", can that be "outlook.com"? I don't actually know what destination systems would be expected to retain the approve/reject option. Does the system, for example, expect that the message will stay within the Exchange environment and therefore be read in a rich client such as Outlook or OWA? We have some users who prefer a plain text email client (yes, even today) and I think this may cause me a challenge as the email doesn't contain any URLs, etc that could be clicked on to activate their choice.
