Scheduled Service Change: FIM updates and synchronizations
During this time, changes made by users in Workday, PeopleSoft, and WhoIAm will not propagate to either the local Active Directory or to Office 365. Mail will continue to be routed as per the user's delivery options as of 5 PM on Friday 1/15.
There is no workaround for this issue
Beginning Friday evening 1/15/2016 and continuing until Sunday 1/17/2016, updates will be applied to Microsoft Forefront Identity Manager (FIM).
