- Device & OS
- not provided
- Scenario
- Attempting to view, update, or synchronize calendar events in the Outlook 2010 desktop client linked to a Microsoft webmail account.
- Observed behavior

Access Your Calendar via Outlook Web App
Since desktop calendar sync is permanently disabled for Outlook 2010, using your web browser is the most reliable and immediate way to manage your schedule.
Microsoft has updated its backend services and ended support for the legacy protocols that Outlook 2010 uses to connect to Outlook.com. Because there is no software patch to fix this, accessing your calendar through the cloud is the official workaround.
Launch your preferred modern web browser, such as Google Chrome, Microsoft Edge, or Mozilla Firefox.
Type outlook.com into the address bar and press Enter. Click the 'Sign in' button and enter your Hotmail, Live, MSN, or Outlook credentials.
Once logged in, look at the left-hand navigation sidebar and click on the Calendar icon. From here, you can view, add, and manage all your synced events.
Upgrade to a Modern Version of Microsoft Outlook
To restore full desktop calendar synchronization, you will need to upgrade from Outlook 2010 to a supported version that handles modern authentication.

Frequently Asked Questions
Why did my Outlook 2010 calendar suddenly stop syncing with Hotmail?
Microsoft has discontinued support for the legacy connection protocols that Outlook 2010 relies on to connect to Outlook.com services, which include Hotmail, Live, and MSN accounts. This backend change prevents the desktop app from syncing new data.
Is there a third-party plugin or workaround to fix the Outlook 2010 sync?
No, there is no supported workaround, registry hack, or plugin to fix this issue. The discontinuation was implemented on Microsoft's servers, meaning Outlook 2010 fundamentally lacks the modern security protocols required to connect.
Can I still receive emails in Outlook 2010?
Yes, you may still be able to configure basic email reception using POP or IMAP protocols. However, these older protocols only sync email messages; they cannot synchronize calendars or contacts.
Does this synchronization issue affect newer versions of Outlook?
Outlook 2013, 2016, and newer versions support modern authentication and can successfully connect to Outlook.com, provided they are updated to the latest builds. The hard block primarily impacts Outlook 2010 and older versions.
