The short version

  • Only Microsoft Outlook has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Xlinesoft the purchase includes one year of support and upgrades only; after that, newer versions require a paid upgrade.
  • They diverge on capability: Microsoft Outlook covers Exchange calendar integration, Xlinesoft covers Database to web application.
  • Prices and features above were last checked on 12 November 2026.

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.

Xlinesoft

  • The purchase includes one year of support and upgrades only; after that, newer versions require a paid upgrade.
  • Multiple database connections, REST API connections and single sign-on through Active Directory, Okta or SAML are Enterprise-only, which raises the price from $599 to $999 per developer.
  • Self-hosted only. Hosting, database administration, backups, runtime updates and access-control configuration remain the customer's job, as Xlinesoft's own product facts page states.
  • Applications built on Microsoft Access require a Windows web server.
  • PHPRunner and ASPRunner.NET are separate products with separate licences, so moving a project between PHP and .NET is not covered by one purchase.

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.

Xlinesoft: How much does PHPRunner cost?

PHPRunner Professional is $599, Enterprise Edition is $999 and MultiDev Edition, which includes three Enterprise licences, is $3,599. Professional and Enterprise prices are per developer, and each purchase includes one year of email support and free upgrades.

Source
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.

Xlinesoft: Which databases does PHPRunner support?

MySQL, MariaDB, Microsoft SQL Server, PostgreSQL, Oracle, Microsoft Access, IBM DB2, Informix, SQLite and ODBC-compatible databases. Using multiple database connections in one project is an Enterprise Edition feature.

Source
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.

Xlinesoft: Is there a free trial?

Yes. PHPRunner can be downloaded and evaluated for 21 days, and public live demos show the generated applications, with add, edit and delete disabled.

Source
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.

Xlinesoft: Where do PHPRunner applications run?

On your own web server. The documented options are Apache and Microsoft IIS with a compatible PHP runtime and database extensions, and a built-in web server is available for local testing. The development application itself runs on Windows, macOS and Linux.

Source
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.

Xlinesoft: What does the Enterprise Edition add?

Multiple database and REST API connections, data encryption, and enterprise authentication including Active Directory, Okta, Azure AD, OpenID and SAML, on top of all Professional features.

Source
Xlinesoft: What is ASPRunner.NET?

Xlinesoft's equivalent builder for ASP.NET. It generates database-driven ASP.NET web applications with the same kind of forms, reports, charts, permissions and Page Designer, and is sold separately from $599.
