Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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.
WebStorm
- JetBrains WebStorm is sold as an annual subscription rather than a one-time purchase: commercial price is $199 per year (USD), and personal price starts at $299 in year one, dropping to $239 in year two and $179 from year three onward with continuous renewal.
- If the subscription lapses, use of new versions stops; JetBrains grants a fallback license only for the last version used while the subscription was active, per its published buy page.

Answered from the vendors’ own pages
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.
WebStorm: Is there a free version of WebStorm?
Yes, WebStorm is free for non-commercial use and includes access to JetBrains AI with a free tier.
SourceMicrosoft 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.
WebStorm: What is the cost of a commercial WebStorm license?
The page references a testimonial mentioning 70 euros as a cost, though specific current pricing requires visiting the dedicated pricing page.
SourceMicrosoft 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.
WebStorm: How does JetBrains AI licensing work?
Users can pay with JetBrains AI credits, bring their own AI subscriptions and API keys to avoid vendor lock-in, or use the free tier included with WebStorm.
SourceMicrosoft 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.
WebStorm: What features does the free tier include?
The free tier includes the smart code editor, navigation tools, integrated developer tools, and customization options.
SourceMicrosoft 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.
