  I am really disappointed in @Apple Business. They finally launch a cloud platform for business mail, but you can’t set up a user mailbox if it was previously used in iCloud+ custom email domains?? I’m being told that it’s not just a 30 day wait, I will never be able to set those mailboxes up. And there’s no user aliases, no multi-domain email support. No multi-tenant offerings (not that I expect that yet). I get that it’s still in its infancy, but come on. These are basic features and they worked with the personal side. I found a way to create user groups with emails that seemed like a workaround to still get mail that’s addressed to these inboxes, but then I found out that they can only be emailed to internally from the same domain. Apple policies are blocking external senders. I spoke to four different support reps over 3+ hours yesterday and they don’t even understand this issue or how to fix it. They keep asking about where the domain is registered when it is clearly an issue deep within Apple systems at a very high level that needs to be changed. I didn’t like the Office 365 integration with the Apple ecosystem, which is why I was so excited for this. But not having access to my mailboxes and not even being able to implement a workaround IS A MAJOR ISSUE. What’s going on @tim_cook? How could this have shipped like this?

  @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.

  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.

  @Marketintel_x @BrodyFord_ @business It’s crap. co-pilot’s worse performance is when you seek its assistance with other Microsoft software. You have better luck using Google to help with Microsoft Office 365 issues.

  ITS is aware there is an issue with users accessing Microsoft Office365 web services. Microsoft is aware that users are impacted & is working to resolve the issue. If you cannot access the web services, please use the desktop applications (Microsoft Outlook, Teams, Word, etc.).

  Looks like there is an @Office365 issue in Europe where everyone's apps are missing.

  The bear case on Office 365 boils down to one thing: does Microsoft participate in the agent-facing side of data work? Right now most people talk to agents through a terminal or some stitched-together texting setup. If Microsoft makes Teams the place you talk to your agents and share work with them, they own the interface. That interface is the moat.
