I have code that creates a distribution list in Office 365 via EWS. I am using direct XML not the managed API. My XML will create the distribution list and populate it. It looks fine in OWA. Then I try to edit the list. I make changes, delete, add members, etc. then when pressing the 'save' button, I get the error "the group can't be updated right now. Please try again later". However, I can edit the list using Outlook. Also, in OWA, I can edit/save a distribution list that I created manually. Any idea what the problem is? Here is the XML of a sample distribution list:
