Microsoft 365 E3 Annual Subscription (12 Months)

Licence

Service Components, as Microsoft Publishes Them

What Microsoft Does Not Publish for This Plan

We leave these blank rather than fill them: a Singapore-dollar list price; any seat minimum or maximum; an end-of-support date; and a per-plan Viva Engage entitlement, which Microsoft publishes for the frontline plans but not for the E plans. We would rather leave a field blank than print a figure we cannot substantiate.

This is a subscription, and it ends. The 12 month term is the entitlement. Microsoft publishes what happens when a business or enterprise subscription is not renewed, and it is worth reading before you plan a renewal date.

Explicit cancellation skips the staged path and goes to data removal directly. We track your renewal dates for you precisely so that this sequence never starts.

Lifecycle

Microsoft 365 sits under the Modern Lifecycle Policy, with a support start date of 22 September 2015 and a retirement status Microsoft publishes as “In Support”. Microsoft publishes no end-of-support date for it. We say that rather than calling it evergreen, because a Modern Lifecycle product can be retired on notice — the point is that no date exists.

Support

Microsoft includes online support through the admin centre and phone support in most countries and regions — billing support during business hours, Monday to Friday, and technical support around the clock. But read Microsoft's own condition carefully: “You must have at least one subscription bought through Microsoft to access Microsoft support. If you bought all your subscriptions through a partner, contact your partner for support.” If you buy this subscription from us, we are your first line of support, and that is by Microsoft's design rather than ours.

Support and Warranty Position

A subscription licence carries no hardware warranty. SourceIT supplies this subscription with local Singapore support and a GST invoice. No warranty term is quoted or implied.

The applications and the mailbox are the same on all three enterprise plans. What you buy as you move up is security, compliance and AI.

A Note on Intune, Where Microsoft's Own Pages Disagree

Microsoft's Intune pricing page states that Intune Plan 1 is included with “Microsoft 365 E3, E5, F1, and F3, Enterprise Mobility + Security E3 and E5, and Business Premium plans”, and that Plan 2 is “an add-on to Microsoft Intune Plan 1”. The enterprise pricing page agrees. The E3 and E5 product pages describe richer Intune capabilities. We publish the narrower reading — Intune Plan 1 included, Plan 2 and the Intune Suite as add-ons — because two of the four pages say so explicitly and the Intune product page is the authority on its own packaging. If Intune Suite capabilities matter to you, price them separately with us rather than assuming they are in the bundle.

Microsoft Publisher Is No Longer Included

Microsoft Publisher has been retired and is no longer part of any Microsoft 365 plan. Subscriber access ends 1 October 2026 and support for the perpetual version ends 13 October 2026. Older third-party descriptions of these plans list Publisher as an included application. It is not one.

Microsoft Teams and the Two Variants

The current position, and it has changed. Microsoft unbundled Teams from the Microsoft 365 and Office 365 enterprise suites with effect from 1 April 2024, outside the European Economic Area and Switzerland — and Singapore falls in that worldwide set. For a period, customers who wanted Teams had to buy a (no Teams) suite plus a separate Microsoft Teams Enterprise licence.

That requirement was lifted on 1 November 2025. Microsoft's licensing announcement states: “Microsoft 365 and Office 365 Enterprise suites that include Teams are once again available to all customers, new and existing.” At the same time Microsoft reduced prices on the suites without Teams and raised the price of the standalone Teams Enterprise licence. Both routes are open to Singapore customers — nobody is forced down either one.

What differs between the two variants. Only Teams is removed; every other entitlement is identical. One caveat worth stating plainly, because Microsoft's own comparison tables show it: on the E5 and E7 plans, Audio Conferencing and Teams Phone are Teams-dependent and Microsoft marks them “Included in Teams versions”. So the suites are equivalent on paper but not functionally identical in that respect.

Is this a one-time purchase?

No. This is a subscription with a 12 month term, licensed per user on an annual commitment. There is no perpetual version of a Microsoft 365 plan.

What happens if we do not renew?

Microsoft publishes a staged path: the subscription is Expired for about 30 days with normal user access, then Disabled for about 90 days during which only administrators can reach the data and apps show “Unlicensed Product”, then Deleted, which cannot be reversed. Microsoft states that data “will be deleted no later than 180 days after cancellation”. We track your renewal date so it never gets there.

Does it include the desktop Office applications?

Yes. This plan includes full desktop installs of Word, Excel, PowerPoint, Outlook and OneNote, on up to 5 PCs or Macs, 5 tablets and 5 mobile devices per user.

How much mailbox storage does each user get?

A 100 GB primary mailbox with a 1.5 TB auto-expanding archive. Microsoft adds storage to the archive incrementally from an initial 100 GB as it fills.

Does this SKU include Microsoft Teams?

Yes. We also list a (no Teams) variant at a lower price for organisations that license Teams separately.

Do we have to buy the no-Teams version and add Teams separately?

Not any more. That was the position from 1 April 2024, but Microsoft reversed it on 1 November 2025: suites including Teams “are once again available to all customers, new and existing”. Both routes are open.

Is there a minimum number of seats?

Microsoft publishes none. Its plan-options service description lists these plans under “unlimited users”. Anyone quoting you a minimum is quoting their own commercial terms, not Microsoft's.

Is Microsoft Publisher included?

No. Publisher has been retired: subscriber access ends 1 October 2026 and support for the perpetual version ends 13 October 2026. Older third-party descriptions of this plan list it; that is out of date.

When does support for Microsoft 365 end?

There is no published end date. Microsoft 365 is under the Modern Lifecycle Policy with a retirement status of “In Support”.

Who supports us if something breaks?

We do, first. Microsoft's own documentation states: “If you bought all your subscriptions through a partner, contact your partner for support.” That is what our Singapore team is for.

Is there a warranty?

Not a hardware warranty — this is a subscription licence and no such warranty exists. SourceIT provides local Singapore support and a GST invoice.
