  @12Knocksinna @Office365 It has become too complex for Microsoft to manage as proven by the numerous issues they cause every day

  @CalebInvests_ Ackman bought $MSFT in Feb when it dipped and looked more compelling on valuation. He probably sees Microsoft as more "embedded" in enterprise, Office 365, Azure, Copilot with stickier revenue and better pricing power compared to $META, which is heavily tied to ad cycles and consumer attention. Wall Street isn’t missing anything big, it’s mostly about price and margin of safety. MSFT just offered a better entry at the time. I believe his entry was around $370 for $MSFT that was a great entry and it provided a great margin of safety. $META would need to go down into $450 area for same margin of safety $MSFT was at $370.

  Passwords get stolen. MFA prompts get approved. Rob Allen explains why some organizations are now locking SaaS apps like Office 365, GitHub, and Salesforce to specific trusted IP paths instead of exposing login access to the entire internet. Even if an attacker has credentials, they still can’t connect unless traffic comes from the approved location. Is location-based access control becoming the next layer after MFA? #Cybersecurity #SaaS #IdentitySecurity

  @medsci_yb3r @MicrosoftLearn @Microsoft Tenant😬overcomming 'problems' to sign-out edu-Office 365, a new private Office licence is running, other licence associated with edu-office(.)com says 'Connection failure'. .. but, I can use edu-licence Office 365 again, after a year of non-functional licence. Chaos? Reality.

  @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.

  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

  Looks like you may be using Office 365 which is online. Better to buy a one-time purchase to install on your PC or Mac. Office Home 2024: £119.99 Office Home & Business: £249.99 Fully supported with updates and trouble shooting.

  @KingDamilotun XLOOKUP (This only works on latest version of excel like Office 365 and has inbuilt error msg) INDEX-MATCH (works on older version of Excel, but more complex to write. The downside here is that you'd have to wrap it in an IFERROR function to return an error msg)

  @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.

  @domster @bradgessler Our biggest are by far the ones that support our PowerPoint for Office 365 add-in. Places where you have a JavaScript API where it’s impossible for it to be managed on the server.

  Two very different setups. $CLOV (Clover Health) — not in today's scrub, but running off a REAL catalyst. 🟢 Medicare 4.5-star upgrade via federal COURT ORDER (court forced CMS to re-rate) 🟢 Covers 97%+ of members on Contract H5141 🟢 Higher star rating = higher CMS reimbursement rates in 2027 🟢 Q1 2026: GAAP profitable, revenue +62% YoY 🔴 Already up 18.9% yesterday — needs consolidation first This is a fundamental re-rating, not a pump. Medicare stars = real dollars. Entry: $4.70–$5.00 on pullback | T1: $6.20 | T2: $7.50 | Stop: $4.20 $MSFT (Microsoft) activity score 522 — #3 on the full scrub. 🟢 Enterprise AI Copilot embedded in Office 365, Teams, Azure — the deployment layer 🟢 Down 14% YTD = multiple compression on a franchise business 🟢 #3 scrub = institutional money starting to re-rate 🔴 ORCL's $40B raise rattles AI infra capex narrative — watch for spillover At $398, this is best-in-class enterprise AI at a real discount. Entry: $395–$405 | T1: $435 | T2: $460 | Stop: $380

  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.

  @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

  @therahul4402 What's happening with Linux Mint? Windows 11 happened. I did not have serious issues with Windows 10. Log into your MS account..harder and harder local options. All your personal and IP and Work Product files have to be on Onedrive. Copilot. Sales push for Office 365, when anyone with a brain has been using OS for decades. Edge harassment. Poison Updates . Slinking to subscriptions. Eternal cash flow. GFYS with a road flare.

  @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).

  Noticed Microsoft is still shoving stuff down our throats. I have Office 365 without the AI stuff, and noticed the app now has a diamond in the top right corner on apps which is where they push to you AI upgrades.. Just give me the app without all the extra pushed crap.

  @KeithMalinak Autocorrect may have been taking a few days off. Here's a real-life example from my own workplace. Through the miracle of SharePoint and Office365, I'm sharing a document with a Project Manager and we're adding questions and answers as I am refining his request for a change to our production environment. He edited something in the document abruptly last week resulting in colliding words and other jumbled things that I couldn't parse. I highlighted the text and requested, "Please fix these typos when you get a moment. " He fixed the typos and left me a comment in response: "Compelted"

  @nonlinear_james @atalocke I’m using it to manage my work office 365 email right now without any issue. Not IMAP, either. It has native exchange capabilities. Also, WTF is wrong with IMAP? Evolution’s biggest advantage is it doesn’t tether me to a proprietary OS. No copilot BS on my computer!

  So aparrently, the „Smart“ App Control from #Microsoft in the #Windows „Security“-Settings blocks you from installing #office365 … and you have to PERMANENTLY shut off that „Security Feature“ to fix this issue … fml why did i go into IT-Support 🙈😭
