A project accounting lead doing month-end billing reconciliation pulls up a consultant’s timesheet and finds a single day logged at 26 hours. It is almost certainly a typo, someone meant to type 2.6 or fat-fingered an extra digit, but it has already been submitted, approved by a project manager who didn’t look closely, and is sitting in the queue for client invoicing. A few rows down, another resource has logged entries in odd fragments: 7 minutes here, 23 minutes there, none of which line up with the 15-minute billing increments the engagement’s rate card assumes. Neither error is malicious. Both are expensive to catch after the fact, and until this summer, Dynamics 365 Project Operations gave administrators no native way to stop either one at the point of entry.
That gap has started to close. Project Operations now ships two native time entry duration controls that reached general availability within about five weeks of each other in 2026: the ability to configure a maximum daily time entry duration (GA July 24, 2026, tracked in Microsoft 365 message center as MC1425968) and the ability to configure a minimum interval for time entry duration (GA August 31, 2026, MC1443022). Together they give Project Operations something it had previously left entirely to custom validation, whether that meant a Power Automate flow triggered on time entry creation, a plugin registered against the create and update messages, or, more commonly, nothing at all beyond a project manager’s attention during approval.
What the two controls actually do
The maximum daily duration setting lets an administrator define the ceiling on how many minutes a single resource can log across time entries for one calendar day. Per Microsoft’s own release messaging, the configuration is applied from the Parameters page, and it is evaluated every time a time entry is created or modified, not just at submission or approval. That timing detail matters more than it might first appear. It means a resource typing an obviously wrong duration gets an error immediately, in the same session, rather than discovering it later when a project manager rejects the entry or, worse, when it has already cleared approval and shown up on an invoice.
The minimum interval control addresses a different failure mode: durations that are technically valid but operationally useless. Once configured, Project Operations only allows time entries whose duration is a multiple of the value an administrator sets, for example 15 minutes or a full hour. A resource cannot log 22 minutes against a task if the organization has standardized on quarter-hour billing increments; the entry is rejected until it rounds to 15, 30, 45, or 60. Microsoft’s own framing for this feature is squarely about time-tracking policy compliance rather than data hygiene for its own sake, and the distinction is worth sitting with: this is not a cosmetic rounding feature, it is a control meant to make sure recorded time actually maps to how the organization bills or costs labor.
Neither setting appears to expose a granular default in Microsoft’s public documentation beyond the mechanism itself, but field configuration guidance published around the July rollout describes the daily maximum defaulting to a full 24-hour day, meaning 1,440 minutes, until an administrator tightens it. If that reporting holds in your tenant, the practical implication is that this feature does nothing on its own. It has to be explicitly configured to be useful, which is a detail worth confirming in a sandbox before assuming it is protecting anyone.
Rolling out the time entry duration controls without a mess
The temptation with either control is to set the value you actually want on day one: an 8 or 9-hour daily cap matching a standard workday, and a 15-minute increment matching your billing rate card. Resist that instinct for the first rollout cycle. Because validation runs on every create and modify, and because Project Operations time entry has several paths into the system beyond the standard weekly grid, including the Copy Week function, bulk import, and any canvas or model-driven app built against the time entry entity, a tight setting configured without a testing pass tends to surface every non-standard workflow your organization has quietly built up around timesheets.
A safer sequence starts with a maximum daily duration set deliberately loose, something like 16 or 18 hours, purely to catch the genuinely broken entries (the accidental 26-hour day, the decimal-point typo that becomes 240 hours) without touching resources who occasionally work a long day and log it honestly. Watch validation errors for a full billing cycle before tightening toward the actual policy limit. The minimum interval control deserves the same caution, but for a different reason: it will interact directly with any existing Power Automate flows, integrations, or import templates that write time entries with durations your organization never audited closely. An integration pulling hours from a separate scheduling or field service system, for instance, might write entries in whatever granularity that source system uses, and a newly enforced 15-minute increment will start rejecting them the moment it goes live. Map every system of record that writes into project time entries before you set this value, not after.
It is also worth coordinating both settings with how your organization has configured time zone behavior for the time entry grid. Project Operations lets teams choose between time zone aware date handling, where the same entry can display on different calendar dates depending on the viewer’s time zone, and time zone independent handling, which pins the date regardless of viewer location using a dedicated time zone independent date field. For a distributed delivery team spanning multiple time zones, a daily maximum duration check that is evaluated against a date that shifts depending on who is looking at it can produce validation behavior that looks inconsistent to end users, even though the underlying rule hasn’t changed. Confirm which time zone mode is active before assuming daily duration validation will behave the same way for every resource.
What these controls do not solve
Both features validate entries going forward. Neither one appears to retroactively flag or correct time entries that already exist in the system, so a backlog of historical bad data, the kind most organizations discover they have the first time they actually go looking, will not be swept up by turning either setting on. If a data cleanup is part of the motivation for adopting these controls, that remains a separate exercise, likely a Power Platform dataflow or a one-time script against existing records, not something the new parameters retroactively apply.
Equally, neither control replaces approval-stage review. A time entry that respects both the daily maximum and the minimum increment can still be entirely wrong: charged to the wrong project task, misclassified by type, or simply inaccurate about what work actually happened. Duration validation catches a narrow, specific class of error, the kind that shows up as an obviously implausible number or a fractional oddity, and it catches it earlier and more reliably than a human reviewer scanning a timesheet approval queue ever will. It is not a substitute for that review; it removes one category of noise so the review that remains can focus on judgment calls rather than arithmetic.
For organizations running Project Operations at scale, particularly those billing time-and-materials engagements where a single mis-keyed entry can mean a client invoice dispute, these two settings are a genuinely useful, low-effort addition to a governance model that most teams have historically had to build themselves. Getting the rollout sequencing right, testing against every system that writes time entries, and being honest about what the controls do not cover matters more than getting the exact numbers right on day one. Routeget Technologies has walked several Project Operations customers through exactly this kind of parameter rollout, and the pattern holds: the configuration itself takes minutes, and the discovery of what has been quietly writing non-compliant time entries into the system for years takes considerably longer.
