I have followed this article: http://www.yourithelp.co.uk/office-365-create-catchall-wildcard-address-office-365/
For some strange reason, it seems to send emails to the catchall mailbox even though the email address is being sent exists within the catchall mail group.
So for instance we have an email called email@example.com. This address contains all users.
We have another group called firstname.lastname@example.org - This contains all groups, such as all@ which contains all the users and distribution groups too.
So I have a rule that states:
Is sent to a member of group 'email@example.com'
or Is received from 'Inside the organization'
So that there is no way it can go into the catchall mailbox if sent within the organisation. Again for some strange reason this is still occurring, however users are receiving the email too but additionally the catchall mailbox is getting too.
Any ideas on this? No point raising a ticket with Microsoft as they clearly mentioned to me that they do not support this functionality.
Thanks in advance.
