Microsoft’s Exchange Online is throwing a curveball, blocking access to mailboxes via the classic Outlook desktop app for users in Asia Pacific and North America, with the company scrambling to pinpoint the root cause since acknowledging the issue early this morning. This latest hiccup, tracked as incident EX1189820, is also messing with server connections and logins, on top of a separate search glitch in classic Outlook that Microsoft’s investigating from yesterday. While they’re advising affected folks to switch to Outlook on the Web as a quick fix, it’s a reminder that outages like this can disrupt small businesses—think lost productivity and frustrated teams. If you’re an SMB or MSP, keep an eye on Microsoft’s admin center for updates and consider having backup email tools ready, especially after their string of service stumbles over the past month, including DNS and Azure snafus.
