A SharePoint permissions audit produces a spreadsheet, not a fix. That gap is where most governance programmes stall: the export lands in an admin's inbox, gets skimmed once, and sits unused until the next compliance review asks for it again. This guide covers what to do with the findings once you have them, in an order that reduces risk rather than creating new exposure.
Step 1: Rank findings by exposure, not by count
Every audit surfaces more unique permissions than any team can realistically clear in one sitting. Trying to fix all of them at once is how remediation projects die in week two. Sort the list by exposure instead:
- Items shared with "Everyone" or "Everyone except external users" groups.
- Items with active external or guest accounts attached.
- Libraries where a broad group (all employees, all site visitors) was granted edit access instead of read.
- Anything on a site holding financial, HR, or client-confidential content.
A finding with three unique permissions on a low-sensitivity team calendar is not the same problem as one unique permission granting an external contractor edit access to a finance library. Rank by consequence, not by how many rows the finding takes up in the export.
Step 2: Reset broken inheritance on low-risk libraries first
Broken inheritance happens when a library, folder, or item stops following the permissions of its parent and gets its own, separately managed set. Over years, this produces a site where three people can see a folder that the rest of the site membership cannot, and nobody remembers why.
- Open the site's permissions page and identify items showing "This item has unique permissions" instead of inheriting.
- For each one, check whether the unique grant still matches a real business need. Most do not.
- Where the grant is stale, reset to inherit from the parent to fold the item back into normal site permissions.
- Where the grant is legitimate but scoped wrong, adjust the specific permission level rather than removing it outright.
Doing this one site at a time in the native SharePoint permissions UI is workable for a handful of sites. Across dozens of sites with hundreds of flagged items, ShareMaster's Shared Links & Permissions tool audits unique permissions across sites and applies a bulk reset to broken inheritance, so the reset step does not require opening each site's permission page by hand.
Step 3: Remove stale guest and external access
External sharing is the finding category most likely to represent a real security gap rather than internal untidiness. A former vendor, a contractor whose engagement ended two years ago, or a client who was added to a project site and never removed: these accounts often still hold active access with nobody actively checking.
What to check before removing a guest
- Last sign-in date for the guest account (available through Entra ID / Azure AD sign-in logs for the tenant).
- Whether the guest's organisation still has an active relationship with yours.
- Whether the guest has access to more than one site, which can indicate broader exposure than a single finding suggests.
Guests with no sign-in activity in the last 90 to 180 days are the safest candidates for removal. For anything more recent, confirm with the site owner before revoking, since a quiet external partner is not always a departed one.
Common findings and what they usually mean
Most audits surface the same handful of finding types repeatedly. Knowing what each one typically indicates before you dig into the specifics saves time on triage:
- Unique permission on a single document, not a library: often a leftover from a one-off "share this file with a client" action that was never revoked once the reason passed.
- An entire site with a much larger member list than its stated purpose implies: usually points to a site that started as a small team project and was gradually treated as a general-purpose dumping ground for content.
- A distribution list or security group with edit access on a site nobody remembers granting it to: frequently traces back to a request made years earlier for a project that has since wound down, with nobody assigned to clean it up afterward.
- Multiple external domains with access to the same site: worth checking whether all of them are still active vendors or clients, since this pattern often accumulates one relationship at a time without anyone reviewing the cumulative list.
Step 4: Fix the pattern, not just the instance
If the audit turned up the same mistake on twelve different sites, correcting all twelve is only half the job. Find the root cause. Common patterns worth chasing down:
| Pattern seen repeatedly | Likely root cause |
|---|---|
| Sharing links set to "Anyone" instead of "Specific people" | Tenant-level sharing default is broader than the org's policy intends |
| Guest accounts with no expiry | No guest access review process in place, or one that is not enforced |
| Site members with Edit access when Read would do | Default group used when the site was provisioned was too permissive for the content it now holds |
These are policy-level fixes, some of which sit at the Microsoft 365 tenant level and belong with whoever administers Entra ID and sharing settings, not the SharePoint site owner alone.
Step 5: Re-run the audit and document the after-state
Once remediation is complete, export the permissions data again and compare it against the original findings. This is not optional paperwork; it is the evidence a compliance reviewer, an auditor, or your own future self will ask for the next time someone asks "when was this last checked." ShareMaster's Report Master exports a permission matrix to Excel, which makes it straightforward to keep a before-and-after pair of files for the record.
Handling findings you can't remediate today
Not every finding gets fixed in the first pass. A unique permission granted to a director who genuinely needs cross-departmental access is not a mistake to correct; it is a legitimate exception that belongs on a tracked list, not in the "fixed" column of your remediation spreadsheet. Separate findings into three buckets rather than trying to force everything into "fixed" or "ignored":
- Fixed: the access was stale, wrongly scoped, or broader than needed, and has been corrected.
- Accepted exception: the access is intentional, has a documented business reason, and has an owner who signed off on it.
- Needs a decision: nobody currently knows why the access exists, and the site owner or department needs to weigh in before anyone touches it.
That third bucket is usually the largest one after a first pass, and it is fine for it to stay open while you chase down owners. What matters is that it is visible and tracked, not silently dropped once the obvious wins are cleared.
Building a remediation cadence, not a one-off project
A single remediation pass fixes what has already accumulated. It does nothing to stop the same drift from rebuilding over the following twelve months, because the underlying causes (ad hoc sharing requests, one-off external invites, project sites that outlive their original purpose) keep generating new unique permissions every week. Treat the first remediation as the baseline, then schedule a lighter recurring pass:
- Quarterly: re-run the audit, compare against the last baseline, and remediate anything new that meets the same exposure criteria used in the first pass.
- At offboarding: check whether the departing employee's sites and libraries have unique permissions tied specifically to them, since these are easy to miss in a generic account-deprovisioning checklist.
- At project close: fold permission cleanup into whatever process already handles closing out a finished project site, rather than treating it as a separate task nobody owns.
Organisations that treat remediation as a quarterly habit typically spend a fraction of the time on each subsequent pass, because the backlog never has years to compound the way it did the first time around.
Frequently Asked Questions
How long does SharePoint permissions remediation usually take?
For a tenant of 50 to 100 sites, a first remediation pass typically takes a few hours of admin time once the audit data is exported. Tenants with several hundred sites and years of accumulated unique permissions can take multiple sessions, usually spread across a week or two so each pass can be checked before moving to the next.
Should I reset all broken permission inheritance at once?
No. Work through libraries in risk order, starting with the ones where reverting to the parent permission set carries the least chance of disrupting active work, and confirm each batch before moving to the next.
What is the difference between an audit and remediation?
An audit produces a list of findings. Remediation is the follow-up work of acting on that list and applying fixes without breaking legitimate access. Most governance programmes run the audit and skip the remediation step, which leaves the same exposure sitting in the tenant.
