  @RihardJarc Half of its market value is office 365. So you can cut that segment in half, thus reducing its market cap by 25%. I think that segment's going to go down even more

  I cannot believe that a Company as big as @MSFT365Status @Microsoft @Office365 has had an Exchange outage since 9:11AM PST (at least) - resulting in a continued, now 5 hour, outage. So many tenants are unable to send or receive emails, and how there isn't world-class redundant infrastructure in-place for their Exchange server is beyond me.

  @pascal_bornet With that in mind, he will still face the quarterly full screen ads where microsoft after a major updates, tries to push people to onedrive, office 365, and copilot, any any other bloatware they have going at the time (not much of a way to fix that without causing update issues).

  like for example: if you defend an org you will likely have: A firewall/VPN server A router/switch A cloud hosted web server Microsoft office 365 Maybe an Remote Desktop Services (or VDI) Service Your daily world will not be full of zero days exploding inside ur VPN server (unless you have a fortinet :P /s) these are rare events. You will have: Phishing/AITM attacks Scams/BEC Identity Dictionary/Brute Force you will also have malware etc. on box IPS/IDS/EDR alerts for behavioural type stuff (most of these are false positives) so software vulnerabilities on the edge in terms of volume will likely not be ur daily grind! identity will.

  @DeepValue47 On Azure. 👎🏻 If they force their Office dominance they’ll likely force @PalantirTech into the office document space. Office 365 web word support is terrible and everyone knows it. If Palantir integrates Team equivalent capability, the war will be on.

  Silk Typhoon (HAFNIUM), a Chinese 🇨🇳 state APT, has evolved from on-prem Exchange exploitation to cloud-native supply chain attacks, most recently abusing CVE-2025-3928 in Commvault's Azure-hosted M365 backup SaaS to pivot into downstream customer tenants. - Initial access spans three vectors: CVE-2025-3928 (zero-day in Commvault Web Server, T1190), stolen API keys from privileged cloud vendors (T1195), and leaked corporate credentials found on public repos like GitHub (T1078.004). The Commvault campaign gave them client secrets for Metallic M365 backups, opening direct paths into customer M365 environments via hijacked service principals. - Lateral movement pivots from on-prem to cloud by targeting Entra Connect servers (T1210, T1078.002), enabling privilege sync between Active Directory and Entra ID. Credential dumping and key vault theft support pass-the-hash moves (T1550.002) into Azure. - Persistence relies on adding passwords to existing consented service principals or creating new Entra ID applications named to mimic legitimate Office 365 services (T1098.001, T1036). Web shells handle C2 on compromised Azure VMs (T1505.003). - Collection targets email via EWS and MSGraph APIs, plus SharePoint (T1213.002) and OneDrive (T1213.003), all through OAuth apps with admin consent, a low-noise, API-native exfiltration path that bypasses many endpoint controls. #DFIR_Radar

  I wonder how much productivity the entire world economy has lost just from Microsoft products not working as intended. Freelancing for a new company, and they gave me my first Office 365 email that I've ever had to deal with on a professional basis. Within the first 2 hours, it's not even working and won't let me send emails. I'll take "things that would never happen with Gmail" for $500.

  @umarsaif They won't get a chance to become "real". The issue is AI Agents are removing the need for abstraction, UI and unwanted code layers. Entire office suite is now useless. Forget about office 365. Mails, comm channels will survive for sometime. Where Indian IT will contribute?

  @tomhounsell @Chris123NT I'm kinda surprised that office365 still lets me host my domain and forward to my exchange server. But it's still a PITA some services just plain refuse to send to MSFT for no reason (Amazon 3fa) but I get all their ****** Amazon ads ..

  A bizarre glitch in @Microsoft Defender for Office 365 is flagging legitimate @Google search links as malicious, via @BleepinComputer. 🚨 SecOps teams face false-positive chaos as enterprise filtering breaks down. Has your SOC seen this false alarm? #CyberSecurity #Cloud x .com/BleepinComputer/status/2095096870963945811

  @Office365 I am very much frustrated and really very much disappointed with my account of Microsoft 365 account. I am got stuck in loop of authentication MFA For asking help also login required. And how could any one login if authentication is not working.

  Yep this is what I’ve always known. Problem is that Microsoft keeps treating XBox as if it were Windows, Azure, Office 365 and all its other business & productivity products & services, where there’s no respect for games as entertainment, experience and as an art form. #HearYou

  @pitdesi Yeah I was there was there for 2 years at the Mountain View campus one of them being the year he took over as CEO (2014) before moving to Apple in Cupertino. At the time many folks in the company didn’t like how he was deprioritizing a lot of Windows stuff like Windows phone and prioritizing Azure/Cloud and Office 365 running well on mobile (iOS, Android) and web. He was the head of Azure before becoming CEO so not too surprising imo. Also the switch to use Linux for networking layer OS software stack in Azure data centers over Windows Server and wearing the infamous “Microsoft Heart Linux” T-Shirt. All of which were clearly the right moves now but at the time in various lunch room discussions there was a lot of dissent and people thinking he would fail. But now all those dissenters seem to pretend he played no role in Microsoft’s comeback which is amusing. But since I saw it happening first hand and in real time I knew otherwise. I was a skeptic too because I had been raised culturally with the same biases and prejudice that Asians (using Asian in the broad U.S. Census definition) can’t make successful innovative decisions and thus can’t be good CEOs, sadly my own parents use to think that which shows the colonial mindset (even Malaysia was a former British colony) but clearly now we know that’s not 100% true with various success stories. It depends on the individual as it always has. I’m sure there are plenty of bad Indian ethnicity CEOs as there are from any ethnic group in the world, But Nadella is probably one of the overall best CEOs in the world of any race or ethnicity.

  @Diss0lution For many years now, the Office 365 installer is broken in French, instead of showing something like "90% complété" in the system notification icon, it says "90lformat error! complété" - incorrectly parsing the percent sign as a parameter. Trillon dollars company at work.

  It's been a stereotypical Monday. Was awake most of the night. Good news is I didn't have to get up at a certain time for anything. Woke enough to coherent at 1100 am. Text messages from a IT customer about hacked email. Determined that last week he got an email saying to check out this file. It was a PDF stored somewhere else. It grabbed his email password. 😒🫤 Logged in & changed his password. Waited for him to get into office so I could clean his PC remotely. Then reset email password again and give him new one. Meanwhile my van which I bought for $4000 "as is" in February 2001 has decided it's time for the ABS module to fail! 😐 It's a 2009 VW Routan (aka rebadged Chrysler Minivan). I've accepted the fact that I got 5 years and I probably need to just replace it. 😕 Cost of repairs probably around $2500-$3000. And then Finally just saw MS is having issues with Exchange email and parts of the Office 365 product suite. Hopefully everyone else is having a good day.
