- 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.; PagerDuty aIOps, status pages, and live call routing are expensive add-ons not included in base plans, significantly increasing total cost
- They diverge on capability: Microsoft Outlook covers Exchange calendar integration, PagerDuty covers Incident response.

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.
PagerDuty
- AIOps, status pages, and live call routing are expensive add-ons not included in base plans, significantly increasing total cost
- Complex escalation policies require workarounds for scheduling patterns beyond basic weekly rotations
- 5-user minimum requirement forces costs even for small teams, with forced Business tier upgrades adding $12,000+ annually for larger teams

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.
PagerDuty: What is the minimum cost to use PagerDuty?
PagerDuty requires a minimum of 5 users per account. The Professional plan starts at $21 per user per month ($105/month minimum), with annual billing providing 16% discount.
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.
PagerDuty: What integrations does PagerDuty support?
PagerDuty integrates with 750+ monitoring, ticketing, and collaboration tools including Datadog, Slack, Jira, ServiceNow, New Relic, and Nagios.
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.
PagerDuty: How much does AIOps cost in PagerDuty?
AIOps Intelligence is sold separately as an add-on starting at $699 per month, and is not included in any of the base plans.
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.
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.
