  @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.

  @codewith55 Your first step for a new Windows computer is not what to install, but what to uninstall. 1) OneDrive 2) MS-Account (use local login) 3) Copilot 4) Office365 5) Manufacturer & MS Bloatware. Then start your installs. 1) A real browser (Brave, Firefox) 2) LibreOffice 3) VLC

  Office 365 Fix

  DFIR Radar (@DFIR_Radar) reported 14 minutes ago

  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

  @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)

  @12Knocksinna @Office365 I’m assuming that’s because this was used to create nested dynamic group membership that caused too many support issues?

  @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.

  @aakashgupta In all fairness to Microsoft, if the NASA Admin doesn’t set their Office 365 location to #outerfukingspace they might have an issue logging in.

  My voice agent pages a human when something on a call can't wait. It emails whoever's on duty with an acknowledge link. Click it, the alert is marked handled, the ladder stops climbing. Every single one was getting acknowledged within seconds. Before a person had opened the message. Enterprise mail security fetches every URL in an inbound message at delivery. SafeLinks, Proofpoint, Mimecast, Gmail prefetch. This is not new, the email marketing world has been fighting it since at least 2019 when Office 365 started unsubscribing people who never clicked anything, and the fix is the rule HTTP has had for twenty five years: a GET doesn't get to change things. Which I know. Everybody knows. My route had a comment on it saying "GET, because it is the target of a link in an email," which is true, and is not a reason to make it act. GET now renders a confirm button and changes nothing. POST records. There's a test that fetches the URL and asserts the alarm is still armed.

  @satyanadella Wow, you embraced AI as a way to defend your lucrative Office365 suite. You launched co-pilot and failed. Now that you are loosing the AI race and you Office365 franchise you attack the AI you promoted, and launching more solutions looking for a problem.

  @reset_by_peer I'm sure if you removed revenue from pre-existing products where companies crammed in AI without any demand for it and against the user base's general will, just so said companies could claim that revenue was from AI now (products like MS Office 365), actual revenue from explicitly AI products being used by consumers who explicitly want it, would be a rounding error on a rounding error.

  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.

  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 🙈😭

  @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.

  Holy **** GoDaddy is among the worst companies on the planet. Been trying desperately to get them to fix the issue with a domain name previously owned by another company who in the past, used Office 365. Now that my client owns the domain, we can't seem to get them to remove the domain. Microsoft support has been non-existent as well. They assigned a dude to the case, but then he dropped the ball and won't reply to me.

  @KES537 Office 365 email had these suggested replies. When the lady at my work that always emailed me about problems with the software I work on would send me a new problem, I really wanted to click: Let me know how that works out.

  @Mettshish @onestromelufan @NetflixAnime It’s the stupid Indians that work there that caused this whole mess, they have been doing this for a very long time and have been getting away with it for a long long time. Until now this plague has started to reveal itself into the public eye. Office 365 not working in space was just the tip of the iceberg people

  @omninomsky @jiya_3063 WSL helps on windows, and has been quite amazing really. That said, one big "reason" for developing "preferring" windows really comes down to corporate governance and office tools. Many businesses run off Office 365, sharepoint, etc. Yes, you can run these in a browser, but with limitations. Another big reason is governance of machines. Machines are imaged, sent out and a good 25% of their utilization is just off of software like antivirus, threat scanning, etc. It's pretty inefficient, in my view, but can be an uphill battle to change it.

  @grayzoneintel I used to use ther legacy office 365 custom domain email (old OWA and domain control panel) They even blocked important emails from seagate lyve cloud when I was getting it setup and the poor rep and her team worked hours to try to get me to get the login confimation and they even manually tried to send it and it still was rejected by microslop's servers. so I quickly switched to zoho email for my custom domain and got the important confimation email with no problem.

  @EvaAnanova Bro i remember I got put on a migration from a file server to office 365 and share point and this was a key reason I left IT. My manager refused to listen to anyone and forced us to go ahead with this just before Christmas. It didn't work 90% of the machines had 4gb ram

  @WindowsCentral Because...consumer. No human support option on first contact. Only AI, Forums & Forms. Automated responses. It's the same issue as consumer Office 365 user. If you run in a serious problem as data loss or exchange issues, you're screwed. Only commercial customer get a minimum

  @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 ..
