Microsoft is investigating an ongoing issue preventing some customers from accessing their Exchange Online mailbox through Outlook on the web.
While Microsoft says this outage only impacts the North American region,
user reports show that the issue might also affect users in South America (Brazil, Chile, Dominican Republic, and Colombia).
Some South American users also say they're having issues with the Outlook desktop application, which crashes when launched.
"Impact is specific to some users in North America who are attempting to access their Exchange Online mailbox using Outlook on the web," Microsoft said in a new incident report added to the admin center.
"Affected users may encounter an unexpected 500 error when accessing Outlook on the web. We're analyzing any recent deployments that could be contributing to impact and continue to review service monitoring telemetry to locate the root cause of impact."
