    Outlook Security Alert Bug Fixed! Discover How Microsoft Addresses December Update Issue

    Microsoft Outlook Security‍ Alert Issue Resolved by Microsoft

    A recent security ​issue ⁢with Microsoft Outlook has been fixed by‍ the‍ tech giant. The issue was⁢ causing⁣ numerous security alerts to pop up when users would open .ICS calendar files. The issue was first noticed ⁢by users after installing the December 2023 Outlook Desktop‍ security updates.

    The ​root cause of the problem was the CVE-2023-35636 Microsoft Outlook information disclosure vulnerability. This vulnerability could have potentially been exploited by‍ attackers ​to ‍gain access to sensitive information and spread throughout a network.

    The vulnerability⁤ was fixed ⁢in the ⁢Microsoft Patch Tuesday security updates for December,​ but the fix also triggered⁣ inaccurate security ⁢alerts. These alerts would warn users that “Microsoft Office has identified ⁢a potential security concern” and “This location⁢ may be unsafe” when attempting to open ICS files saved locally.

    After receiving numerous reports about the issue, Microsoft confirmed in February that it was a known issue and ⁢promised to find⁢ a fix.⁢ After months of working on a solution, Microsoft has finally delivered a fix⁢ with the release of Outlook for Microsoft 365 Version 2404 Build 17531.20000 in the Beta Channel.

    If you are a Microsoft 365 user and​ have been affected by this issue, you can test‌ the fix by joining the ‌Office Insider‍ Channels.‌ Users on the Current⁢ Channel can expect to receive the fix on April 30th⁤ while those on the Semi-Annual ⁤Enterprise Channel (Preview) ⁢can expect it to be backported during the June‌ 2024 Patch Tuesday.

    In the meantime, affected users can use ⁢a registry key as a temporary workaround to disable the incorrect security ​notifications. However, it’s important to note that this workaround will also ‌stop all other potentially dangerous file types from prompting security alerts.

    To apply the workaround, users ⁤can add ‌a new DWORD key with‌ a⁢ value of ‘1’ to the following paths:

    • HKEY_CURRENT_USER/softwarepolicies/microsoftoffice/16.0/common/security (Group Policy registry path)
    • Computer/HKEY_CURRENT_USER/Software/MicrosoftOffice/16.0/Common/Security (OCT registry path)

    Users can also disable the warning dialogs by following the instructions in the ‘Enable or disable hyperlink warning​ messages in​ Office programs’⁤ support document.

    This ⁤is not the first time Microsoft ‌has ‍encountered issues with Outlook. Last month, they had to address ‍a bug that was causing some⁣ Outlook desktop clients to stop syncing to email servers via Exchange ActiveSync.‍ In February, they also fixed a bug that was⁣ causing connection issues for​ Outlook.com on both desktop‍ and mobile email clients.
