  @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.

  @asaio87 SaaS isn’t dead , but certain SaaS products that aren’t complex and that don’t have risk associated with them will be , and the rest will be open for disruption, especially on price. Not unlike when I automated the backend network/server/os/app layer of office 365 for Microsoft a decade plus ago , allowing them to reduce the per seat cost like 50% or something crazy.

  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 🙈😭

  @NXT4EU We used to have office computers, running on an office server park. No outside computers had access. Micro$oft mandates Office 365 and OneDrive. The server may be in Europe, but where is the backup server. And more important: Who has admin rights over your files?

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

  @moshymiss @JesterJum I run it on Zorin OS, but I also have a Windows 10 box running Libre Office. Runs flawlessly on both. Try it, you won't be disappointed. You can always uninstall it if you don't like it. Although, honestly, I can't fathom why anyone wouldn't like it. All of my work documents are generated by corporate Office 365. I've never had a problem working with any of those documents in Libre Office.

  @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.

  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 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?

  @davibaah @Mr_GeorgeAddo @NITAGhana They don’t even dedicated servers built and managed by the gov. let alone have infrastructure to protect sensitive and critical data… tweaa… imagine NITA ( the nation’s IT branch using subscription of office365). What happened to on-premise and dedicated exchange 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

  @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

  @Microsoft @Office Recently I purchased a laptop in which office365 was included for 1 year, I created an outlook mail and registered it but forgot the password now I am unable to access that mail and the office. When I try to login using the otp it says try with other method

  @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

  Did you know that personal devices can become gateways for corporate data breaches? A recent case revealed a malware attack that accessed Office 365 through a compromised BYOD. The fix? Continuous monitoring and behavior analysis! How secure is your work device? #CyberSecurity
