Microsoft investigates disruption affecting users across Americas

Microsoft is investigating service disruptions affecting users trying to access their Exchange Online mailboxes across multiple regions in the Americas.

In an update Thursday, the company said users are experiencing connectivity issues through multiple methods of accessing their email.

Microsoft says it has identified elevated infrastructure loads across several regions as a likely cause of the problem.

The company determined the increased load is not the result of a surge in user traffic, but rather a number of servers becoming unexpectedly unavailable.

That has placed additional strain on the remaining infrastructure, contributing to connectivity errors.

Microsoft says it is working to safely restore the affected servers and return the service to normal.

It has not yet provided a timeline for when all affected users can expect full service to be restored.
