Exchange Administrator of a O365 tenant that is using either DirSync or AADSync are no longer supported and may not work correctly. These tools are no longer supported as of April 2017, and after December 31, 2017 O365 team are not able to guarantee your connections from Windows Azure Active Directory Synchronization (DirSync) or Azure AD Sync work properly. This may affect your ability to synchronize your local directory infrastructure with Office 365, and will result in users being unable to log in to their Office 365 services.
Azure Active Directory (AAD) Connect is the best way to connect your on-premises directory with Azure AD and Office 365. Upgrade your sync functionality to the latest version of Azure AD Connect, which is the currently supported tool for syncing data to O365 cloud features.
People often wonder how they can safely dispose of their old computers without it costing too much. Here's a guide to a totally free method that I came up with.
1. Remove the hard drive, put a drill bit through it until you hear the platters inside shatter. Toss it in the bin. 2. Run a cleaning rag around the case and make it nice and shiny. 3. Place the computers in full view on the back seat of your car. 4. Park car in a quiet public car park with the windows cracked just enough so it's easy to reach in an unlock one of the doors. 5. Go and have some lunch or dinner.
When you return, I can almost guarantee the computers will be gone.
