The short version

  • Each has a real cost: Google Chrome manifest V3 replaced blocking webRequest with declarativeNetRequest, which imposes hard caps on the number of filtering rules an extension can apply, so uBlock Origin does not run on Chrome and its Lite version blocks measurably less; if content blocking matters to your users, this is not a setting you can change.; Microsoft Outlook microsoft is replacing the classic Win32 client with the new web-based Outlook, and the new one runs only web add-ins, not COM add-ins, so any line-of-business integration for CRM, dictation, document management or telephony must be rewritten or the desktop stays on classic until its support window closes.
  • They diverge on capability: Google Chrome covers Chrome Browser Cloud Management, Microsoft Outlook covers Exchange calendar integration.

What people use each for

The jobs each tool is most often brought in to do.

  • Executive assistants managing someone else's calendar and mailbox through delegate access, which no IMAP client supports properlynot Google Chrome
  • Regulated environments that need retention policies, legal hold and eDiscovery applied to mail centrally rather than per usernot Google Chrome
  • Teams handling shared inboxes such as support or accounts, where permissions and tracking matter more than the mail client itselfnot Google Chrome

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Google Chrome

  • Manifest V3 replaced blocking webRequest with declarativeNetRequest, which imposes hard caps on the number of filtering rules an extension can apply, so uBlock Origin does not run on Chrome and its Lite version blocks measurably less; if content blocking matters to your users, this is not a setting you can change.
  • The browser is the entry point to Google's account, search and advertising business, and the defaults, prompts and sign-in flows all pull towards a Google account; running it fully detached is possible but requires policy and ongoing attention as new prompts are added.
  • Site isolation runs a process per site, which is correct security design and expensive in memory; on machines with 8 GB and users who keep dozens of tabs open it produces genuine slowdowns and support tickets that no configuration removes.
  • The four-week release cadence means a new major version roughly every month, and even Extended Stable delivers one every eight weeks, so any environment that formally certifies browser versions is permanently behind or permanently re-certifying.
  • Because it ships features first and holds the majority of the market, a team that tests only in Chrome builds against Chrome-specific behaviour and finds out about Safari and Firefox breakage from users rather than from CI.
  • Google has reversed direction on Privacy Sandbox repeatedly, announcing third-party cookie deprecation, delaying it several times and then abandoning it in 2025 before retiring several of the replacement APIs, so any advertising or measurement plan built on Chrome's stated roadmap has had to be rebuilt more than once.

Microsoft Outlook

  • Microsoft is replacing the classic Win32 client with the new web-based Outlook, and the new one runs only web add-ins, not COM add-ins, so any line-of-business integration for CRM, dictation, document management or telephony must be rewritten or the desktop stays on classic until its support window closes.
  • The new client's handling of non-Microsoft accounts synchronises mail through Microsoft's cloud rather than connecting from the machine to the provider, which several organisations' data residency and handling policies do not allow, and it is not an optional behaviour.
  • PST and OST files are a single-file, corruptible and effectively unshareable store, and the new client's reduced PST support means years of personal archives sitting in those files need an explicit migration plan rather than carrying forward.
  • Large mailboxes turn software problems into administration ones: search index rebuilds, OST files of tens of gigabytes and the mailbox quotas of whichever plan was bought, and the usual fix is archiving policy rather than anything a user can do.
  • Against IMAP or Gmail you lose most of what justifies it, including free/busy lookup, room booking, delegate access, and retention and compliance policies, because those are Exchange server features rather than client features.
  • The five or six products sharing the Outlook name have materially different feature sets, so internal documentation, training and support procedures must be written per platform and a user moving between desktop, web and mobile finds the same task done differently in each.

Answered from the vendors’ own pages

Google Chrome: Why does uBlock Origin no longer work?

Chrome's Manifest V3 removed the blocking webRequest API that it depends on and replaced it with declarativeNetRequest, which limits how many rules an extension may register. uBlock Origin Lite works within those limits and blocks less. Firefox retains the original API.

Microsoft Outlook: What is the difference between classic Outlook and the new Outlook for Windows?

Classic is the long-standing Win32 application shipped with Microsoft 365 and Office LTSC. The new Outlook is a web-based client that replaced Windows Mail and Calendar. The most consequential difference is add-ins: the new client supports only web add-ins, not COM add-ins.

Google Chrome: Is Chrome the same as Chromium?

No. Chrome is Chromium plus Google's proprietary additions: certain media codecs, Google account sync, Safe Browsing integration and usage reporting. Chromium builds omit those, which is why some sites' video playback and sign-in behaviour differ.

Microsoft Outlook: How long will classic Outlook be supported?

Microsoft has stated support through at least 2029. That is a planning window rather than a reprieve, and organisations with COM add-in dependencies should be scoping the replacement work now.

Google Chrome: What does enterprise management cost?

Nothing. Chrome Browser Cloud Management, the administrative policy templates and Extended Stable are all free. This is unusual and is a genuine reason organisations standardise on it.

Microsoft Outlook: Can I use Outlook with Gmail or another IMAP provider?

Yes, but with reduced capability. You lose free/busy lookup, room booking, delegate access and server-side compliance policies, because those come from Exchange rather than from the client.

Google Chrome: How often does it update?

A major version every four weeks on the stable channel, with security updates in between, and every eight weeks on the Extended Stable channel intended for managed fleets.

Microsoft Outlook: Is Outlook free?

Outlook on the web and the mobile apps are free with a Microsoft account, and the new Outlook for Windows is included with Windows 11. The classic desktop application requires a Microsoft 365 subscription or an Office perpetual licence.

Google Chrome: Is Chrome on iPhone actually Chrome?

No. Apple's platform rules mean it runs on WebKit, so on iOS you get Chrome's interface, sync and account integration on top of Safari's engine, not Blink.

Microsoft Outlook: Will my COM add-ins work in the new Outlook?

No. The new client supports only the cross-platform web add-in model. Vendors must publish a web add-in, and where they have not, the choice is to stay on classic Outlook or replace the integration.
