I'm one of 2 global administrators on our Office 365 system and both of us have taken the 'early upgrade' option - everybody else gets upgraded on 17th August. Since upgrading neither of us have been able to access the mail flow rules although all of the existing rules are working. From what I understand the rules should be accessible from the Exchange Admin page under 'mail flow' but we only have 'delivery reports' and 'accepted domains' with no other options.
In order to work around this I created a new account which I made a global administrator and use to manage the rules using the older interface which still works. However, after 17th August this account will also be upgraded leaving us without access to our rules which is not a situation I want to be in.
Any advice would be welcome!
