For several customers we have configured the Directory Synchronization for Offcice365.
In most situations DirSync reports some Active Directory issues during synchronization, which is delivered by e-mail.
Although most error report and notification are sent to the Global Administrators, the DirSync error will only be delivered to the Technical Contact email address. To configure the technical contact for your tenant you can perform the following steps.
1. Open the Office365 Management Portal
2. Click on the name of your Company (in the upper right for O365 new-style, in the upper left for O365 old-style)
3. Update the technical contant e-mail address and press Save
