📧 Microsoft is investigating a known issue that prevents some Classic Outlook users from sending messages via Outlook.com, causing non-delivery reports that indicate permission errors (0x80070005-0x0004dc-0x000524). The problem is more likely when the Outlook.com account is an Outlook profile linked to another Exchange account or when an Exchange Online mail contact shares the same SMTP address. Microsoft published temporary workarounds — remove the M365 account Address Book, hide the Outlook.com contact in the Global Address List, create a fresh Classic profile with only the affected account, or use the New Outlook client or webmail until a permanent fix is deployed.

⚠️ EvilTokens is a commercially sold phishing kit that abuses the device code authorization flow to hijack Microsoft accounts and enable advanced BEC operations. Distributed via Telegram, campaigns deliver document lures with QR codes or links to phishing templates impersonating trusted services and workflows. Victims are prompted to authenticate on the real Microsoft device login, producing short-lived access tokens and refresh tokens that give attackers immediate and persistent access. Sekoia reported global campaigns and published IoCs and YARA rules; the author says support for Gmail and Okta is planned.

🛠️ Microsoft released an out-of-band update, KB5086672, to replace the broken March preview KB5079391 and address installation failures that produced Error 0x80073712 on Windows 11 24H2 and 25H2 systems.

If that setting is off, install via Settings > Windows Update > Download & install.

🛡️ Microsoft Defender Experts (DEX) observed a late-February 2026 campaign leveraging WhatsApp messages to deliver malicious Visual Basic Script (VBS) files. Executing the VBS creates hidden folders under C:\ProgramData, drops renamed legitimate Windows utilities, and uses them to download additional payloads from cloud services such as AWS, Tencent Cloud, and Backblaze B2. Attackers escalate privileges, tamper with UAC and registry settings, and install unsigned MSI packages to establish persistent remote access. Microsoft recommends hardening script hosts, monitoring cloud traffic and registry changes, and enabling Defender protections.

🛠️ Microsoft has resolved a bug that caused the classic Outlook client to crash when the Microsoft Teams Meeting Add-in was enabled. First reported on March 12 and tracked under incident EX1254044, the issue occurred when older Outlook builds used the Teams Meeting Add‑in build 1.26.02603, for example Current Channel Outlook <= Version 2402 (Build 17328.20142). A fix is rolling out with Teams version 26058.712.4527.9297; Microsoft recommends updating Outlook to the latest build or performing an Online Repair for click‑to‑run installs. As a temporary workaround, users who must remain on an older Office build can disable the Teams Meeting Add‑in via Outlook Safe Mode (Ctrl on launch) and the COM Add‑ins dialog.

🔁 Tycoon2FA, a phishing-as-a-service platform disrupted by Europol and Microsoft on March 4, has returned to pre-takedown activity levels within days. CrowdStrike observed a brief decline to about 25% of normal volumes on March 4–5, 2026, before activity rebounded and cloud compromise remediations returned to early-2026 levels. The service continues to use similar TTPs targeting Microsoft 365 and Gmail, exploiting redirection, URL shorteners, and compromised domains. CrowdStrike warns that without arrests or physical seizures, operators can quickly recover and replace impacted infrastructure.

⚠️ Microsoft is addressing an intermittent Exchange Online outage that has blocked some users from accessing mailboxes via Outlook mobile and the new Outlook for Mac client since Thursday. The company traced the issue (incident EX1256020) to a newly introduced virtual account and is reverting that change across affected environments. Restarts failed to resolve the problem, and Microsoft is working on a permanent remediation and will provide a timeline when available.

⚠️Microsoft reported large-scale IRS-themed phishing campaigns in February 2026 that targeted more than 29,000 users across 10,000 organizations, using tax refund, payroll and W‑2 lures to harvest credentials and deliver remote access tools. Attackers leveraged Phishing-as-a-Service kits (notably Energy365 and SneakyLog/Kratos) and abused legitimate RMM products such as ScreenConnect, Datto, and SimpleHelp to maintain persistent access. Microsoft advises enforcing 2FA, applying conditional access, and blocking malicious domains and payloads to reduce exposure.
