Microsoft confirms Outlook 0x80049dd3 sign-in error, access denied on Windows bug
Users of the Outlook desktop application for Windows 10 and Windows 11 are currently facing a frustrating hurdle, as many report encountering the error code 0x80049dd3. This issue has rendered the app nearly unusable, preventing users from signing in and accessing their emails. Microsoft has acknowledged the situation, stating that it is investigating these isolated reports of malfunctioning Outlook clients.
Interestingly, the 0x80049dd3 error does not appear to be linked to any recent Windows updates, so users can rest assured that uninstalling the latest updates for either operating system will not resolve the issue. One enterprise customer shared their experience with Windows Latest, revealing that they encountered the error upon attempting to access their work email through the Outlook desktop app.
Upon opening Outlook, users are met with an “Access Denied” message under the Inbox section, which effectively locks them out of their drafts, sent items, spam, and other folders. The application prompts users to sign in again, offering options to either “Continue” or “Manage account.” However, selecting “Continue” often leads to another pop-up indicating that the sign-in has failed, accompanied by the same error code, urging users to try again later—a request that proves futile even after multiple attempts.
In our observations, the error also includes a unique identifier and timestamp intended for troubleshooting, but it seems that even Microsoft support is struggling to provide a solution for the 0x80049dd3 error.
How do you fix Outlook sign-in issues in Windows 11?
Despite the challenges, there is a workaround that some users have discovered: closing the sign-in prompt can temporarily restore access to emails. However, this fix is not without its drawbacks, as the error reappears when users attempt to access Outlook again.
The Feedback Hub reveals that this issue is widespread, with numerous users sharing similar experiences. One user reported that when using the New Outlook email program, they encountered the same sign-in prompt, which, when canceled, allowed them to access their emails normally. Another user echoed this sentiment, stating that they received an “Access Denied” message but could view their inbox after dismissing the prompt.
Additionally, a user utilizing Microsoft 365 Family noted that they could see their inbox momentarily before being prompted to log in, only to face the error again shortly thereafter. This pattern of intermittent access seems to be a common thread among those affected.
Microsoft has confirmed that it is aware of the ongoing issues and is working on providing further updates. As users navigate this frustrating situation, many are left wondering if they, too, will find themselves caught in the cycle of prompts and error messages. If you are experiencing similar difficulties with Outlook, sharing your experience in the comments may provide some solace in knowing you are not alone.
