Office 365 Outages: Business Impact

While there are now more modern collaboration tools than ever, email is certainly not dead. When Exchange Online goes down or suffers performance issues many organizations are DISRUPTED. 

In this case, end-users ability to send/receive mail was impacted ultimately disrupting end-user productivity
. Perhaps, an employee on your sales team was planning on sending out a proposal that was time-sensitive. This issue then multiplies and suddenly your help desk is overwhelmed with users complaining. 

Outage happen. Murphy's law tells us "what can go wrong will go wrong." Given that we know that cloud outages will continue to happen organizations need to take ownership internally and prepare for business continuity. 

  • How will IT be alerted of these issues (proactively or when end-users start to complain)?
  • What will IT inform end-users?
  • Are there alternate (temporary) technologies your team can leverage?
