  @marcelhaasIO @MaxBrodeurUrbas @satyanadella All my accounts use the same email and sometimes different passwords. The average user does not know he needs to save the credentials as “azure login”, “office 365 login”, “exchange admin login”. Dude it’s a mess.

  @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

  "GitHub's scale is unprecedented." No, it really isn't. GitHub: 150M total users. Office 365: 345M total users. Xbox: 500M monthly active users. Bing: 100M+ daily active users. The company that runs Office, Xbox and Bing can run GitHub. If reliability is slipping, that's a priorities problem, not a scale problem.

  @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).

  @jimcramer $MSFT has now gone red. AI must be chowing down on Windows and Office 365.

  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

  @EvanOwen @tmnxeq @RhoRider I get where you are coming from. It does help *if implemented well*, just like any other software or process. It is way to early to judge effectiveness since most of the businesses are just having people use ChatGPT for random stuff and using copilot in office 365. When I did software consulting many clients would tell me they were “in the cloud” when all they meant is they have office 365 subs and a terrible sharepoint inplementation. AI is the same way. It will be several *years* before AI is used effectively in enterprise scenarios.

  Steve Ballmer explains the accountability trap inside founder-led companies. He had been Microsoft's 30th employee. When he became CEO in 2000, he says the first year was miserable: "Bill didn't know how to work for anybody." "I didn't know how to manage Bill." Then Gates gave him the line that changed the job: "I'm happy to help you any way, but I don't want you to need me." Ballmer says that was when it hit him: "We're not partners anymore. I have to take accountability." After Gates left, Microsoft pushed into Bing, Office 365, Azure, Surface, and hardware. Then Ballmer gives the scoreboard: "I started a company that had about $2.5 million of revenue and 30 people." "I left a company that had $22 billion in profit." I have seen this handoff problem inside scaling companies. The hard part is not respecting the founder. The hard part is knowing when the company needs one accountable owner of the decision. The diagnostic I would use: if the old partner still has veto power but no longer owns the result, the org is already confused. - Steve Ballmer on Bloomberg Television

  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.

  @S4m4_VT @Pirat_Nation Not a Linux problem, 99% of games do works on Linux tho but via workaround (That got simplified by steam in a remarkable way) As for softwares, welp you're not going to use Office 365. You have to adapt and find the right tools that works with your machine.

  @unusual_whales Will AI need Office365? If not, Microsoft will be in trouble

  @FinanceDirCFO But rather "subprime AI", right? SaaS stocks go down because people don't get business, and think that Dropbox, LinkedIn, Spotify, Office 365, Slack, Netflix, Instagram etc. will go out of business simply because "anyone can vibe code their own version".

  @AiwithLucas_ Your analogies fail. These AI agents are still using M$ tools. If Netflix used Blockbuster as the source for their videos, Blockbuster would still be around. The Goodyear analogy works because just as self driving cars still rely on tires, AI will still rely on M$ services. Switching to "background infrastructure" does not hurt M$. M$ makes MORE money off of server apps and cloud services, such as Active Directory, Exchange Server, SQL Server, Azure, etc, than it does from the Office 365 services you're talking about AI reducing. Where do you think AI agents live?
