ADManage - Build 6659

For O365 Mailboxes, we are able to Add a permission (example, give someone Full access to another mailbox), however, if we try to remove that permission, ADManage reports "Success", but the permission is never removed in Office 365.

Steps in AD Manage:
1. Click on Office 365 Tab
2. Click on Management
3. Click on Mailbox Management
4. Click on Modifiy Mailbox Delegate Permissions
5. Check the "Modify Full Access" Checkbox
6. Select "Add Permissions" Radio Button
7. Select User from List
8. Enter name of mailbox to apply the permission to in Search Box
9. Click Search
10. Check the user mailbox to apply permission to
11. Click Apply
12. Confirm permission has been applied in O365 portal
13. Go back to ADManage
14. Click on Office 365 Tab
15. Click on Management
16. Click on Mailbox Management
17. Click on Modifiy Mailbox Delegate Permissions
18. Check the "Modify Full Access" Checkbox
19. Select "Remove Permissions" Radio Button
20. Select User from List
21. Enter name of mailbox to apply the permission to in Search Box
22. Click Search
23. Check the user mailbox to apply permission to
24. Click Apply
25. We check O365 Portal, and confirm permission was NOT removed.

We have checked the audit logs on our O365 tenant.  We see an entry for the add permission task, but no entry is ever create for the remove permission as if ADManage never connected to issue the command.
