What happened?Microsoft experienced a widespread global service disruption affecting access to Exchange Online mailboxes and related Microsoft 365 services. Microsoft has now confirmed full restoration of the affected services (incidents EX1550543 / MO1550821). Microsoft identified the cause as a technical issue introduced during an earlier network capacity upgrade — it was not a cyberattack. What is being done?No further action is required. Our local IT team has closed monitoring of this incident. If you are still experiencing issues accessing email or files, please contact the IT Help Desk — at this point it would likely be a local issue rather than part of the outage. Thank you for your patience.
