11/22/2015 20:06: Microsoft is still working on fixing the handful of accounts. We've verified that only 4 are current faculty and staff. The others are alumni and retirees. Monday morning, if the accounts aren't already fixed, we will contact the 4 faculty and staff directly via phone to inform them of next steps.\n\n11/22/2015 08:39: All Active Directory entries appear to be functioning correctly now. \n\nA handful of Office 365 accounts are still not working. They are fully intact, except for the emails that were returned to sender while the accounts were unavailable, but we've determined that Microsoft will need to make the changes required to get them working again. We're in the process of coordinating this effort.\n\nA message describing what happened was sent to all affected users on Friday. See a copy at the Verified Communications page (CUWebLogin required): https://www.it.cornell.edu/security/verified_detail.cfm?doc=187 \n\nThank you very much for your patience during this process. 11/22/2015 20:06: Microsoft is still working on fixing the handful of accounts.

We apologize for the delay. CIT is working with Microsoft to reconnect Office 365 email access for the Active Directory accounts that were accidentally deleted. \n\nAll affected email accounts are intact, but any incoming mail *received during this outage* will bounce until the accounts are reconnected. \n\n*After* this issue is resolved, all affected users are advised to contact anyone regarding email they were expecting which hasn't arrived. It's possible it may have been sent, but not received. \n\nWe will email all affected users with information about exactly what happened and so on, when the accounts are back online.\n\nThank you for your patience.

Users can log into email at this time. However, some or all email may *appear* to be missing. Please be reassured that there is no cause for alarm. All affected email accounts are completely intact. We are in the process of merging newly activated accounts with the accounts that existed prior to the deletion in Active Directory.\n \nCIT is working overnight to ensure everyone is back up and able to work without inconvenience as soon as possible. We will provide an estimate for when all accounts will be restored as soon as we have that information. Thank you for your patience.\n\nThe following services were impacted prior to the 1700 entries being restored in Active Directory: Directory Services, Accounts and Access, Email and Calendar, Collaboration Tools (SharePoint, Lync, Yammer, OneDrive), and possibly other AD related services such as local file sharing and printing.\n\nPlease report any further issues with services, other than email and calendar--which we're still working on, to the IT Service Desk: http://www.it.cornell.edu/support/\n Users can log into email at this time.
