🎯Microsoft is fixing some problems with Outlook that make it hard for people to send emails or connect their accounts. They just solved a big issue that was stopping some emails from going through, and they are working on other fixes too.
What Happened
Microsoft is currently investigating multiple issues affecting the classic Outlook desktop client. Users have reported problems with email synchronization and connectivity, particularly when trying to create groups or sync Gmail and Yahoo accounts. The primary issue arises when Exchange Web Services (EWS) is enabled, leading to frustrating error messages like "Can't connect to the server." This problem is tied to a failure in the Active Directory Graph call, which is essential for validating group properties.
Recently, Microsoft resolved a significant issue that was preventing some users from sending emails via Outlook.com. Affected users encountered non-delivery reports (NDRs) with error codes 0x80070005-0x0004dc-0x000524, warning that their messages could not be sent. This issue was more frequent when the Outlook.com account used for sending emails was linked to another Exchange account. Microsoft implemented a server-side fix on April 3, 2026, to address these email delivery issues.
In addition to the group creation issue, another bug is causing synchronization errors for Gmail and Yahoo accounts. Users who change their passwords in Outlook are not prompted to sign in again, which can lead to further complications. Microsoft is actively working on solutions for these problems and has communicated its plans to release updated functionality that utilizes REST APIs to resolve the group creation issue.
Who's Affected
The issues primarily affect users of the classic Outlook desktop client, particularly those using it in conjunction with Gmail and Yahoo accounts. Those who have enabled EWS for their tenants are experiencing the most significant disruptions. Additionally, the mouse pointer disappearing in Outlook has been reported, impacting user experience across Microsoft 365 applications, including OneNote. This widespread impact means that many users are currently facing challenges in managing their emails efficiently.
What Data Was Exposed
While no sensitive data has been exposed due to these issues, the disruptions can lead to significant inconveniences for users relying on Outlook for their daily communications. The inability to sync emails or create groups can hinder productivity, especially for businesses that depend on these functions for collaboration. Microsoft has not indicated any data breaches or leaks associated with these problems, focusing instead on resolving the technical glitches.
What You Should Do
For users experiencing these issues, Microsoft recommends several temporary workarounds. If you encounter the group creation error, try using the new Outlook client or Outlook Web Access (OWA) instead. For Gmail and Yahoo sync problems, deleting specific registry entries related to the affected email accounts may help. If the mouse pointer disappears, users can attempt to click on an email or switch to another Microsoft 365 app to restore visibility. Microsoft advises affected users to open support cases and submit diagnostic logs to assist in troubleshooting. Keep an eye on updates from Microsoft for permanent fixes as they work to resolve these issues.
Microsoft's proactive approach to resolving these issues illustrates its commitment to user experience, particularly as it navigates the complexities of integrating various email services and functionalities within Outlook.
