Planned Microsoft 365 system outage
The IT Infrastructure team is planning a system outage from August 14 – 16 to migrate our Microsoft 365 (M365) tenant. While all systems will not be unavailable at the same time, different services and applications will experience varying periods of downtime throughout the weekend.
What to expect August 14 – 16
Different services will be affected at different times. Not every Centerstone system will be unavailable all weekend.
By Friday, August 14
5 p.m. CT / 6 p.m. ETPrepare before migration
Make sure you are signed in to your Centerstone-issued computer. Close Outlook and OneDrive, then lock the computer and leave it powered on when possible. Do not restart or shut it down unless instructed by IT.
If you have shared files or folders from OneDrive, make sure you have run the sharing report before migration begins. Keep the report as a reference for sharing them again afterward.
