Summary

This article helps you troubleshoot "Access Denied," "You need permission to access this item," and other permission errors in SharePoint Online. These errors occur when you do not have the right access level for a site, library, folder, or file. Most steps can be performed without administrator rights — and the article tells you exactly when to escalate to IT.

In this guide

• 1. Verify the Link Is Correct
• 2. Request Access (If Prompted)
• 3. Check If You Are Signed In with the Right Account
• 4. Check Your Permission Level
• 5. Check If the File Has Unique Permissions
• 6. Check If a Sharing Link Has Expired or Been Revoked
• 7. Clear Your Browser Cache
• 8. When to Contact IT

Before You Start

• A Microsoft 365 account.
• The URL or link to the SharePoint site, library, or file that is giving the error.

Instructions

1. Verify the Link Is Correct

Before troubleshooting permissions, make sure you are using the right URL.

1. Check the URL in your browser address bar — a typo or outdated link can point to a site that does not exist or that you were never granted access to.
2. Ask the person who shared the link to re-send it — the original link may have expired or been revoked.
3. Try accessing the parent site (e.g., if https://company.sharepoint.com/sites/Marketing/Shared Documents/Report.xlsx fails, try https://company.sharepoint.com/sites/Marketing) to see if you have access to the site itself. If a re-sent link gives the same error, the URL is not the problem and the permissions are. Continue to Step 2.

2. Request Access (If Prompted)

When SharePoint shows a "Request access" button, use it — it sends a notification directly to the site owner.

1. Click Request access on the error page.
2. Enter a brief reason why you need access (e.g., "I need to review the Q2 budget report for my project.").
3. Click Send request.
4. The site owner receives your request and can grant access. You will receive an email when access is granted.

Tip: If you do not hear back within a business day, contact the site owner directly (via Teams or email) to follow up on your request.

If the error page shows no Request access button, there is nothing to send and the cause sits elsewhere. Continue to Step 3.

3. Check If You Are Signed In with the Right Account

If you have multiple Microsoft accounts (e.g., a work account and a personal account), you may be signed in with the wrong one.

1. Click your profile icon in the top-right corner of the SharePoint page.
2. Verify the account shown is your work account (e.g., [email protected]).
3. If you are signed in with a personal account (e.g., [email protected]), sign out and sign back in with your work credentials.
4. If you are using a shared or public computer, open an InPrivate or Incognito browser window and sign in with your work account. If the profile icon shows your work address and an InPrivate window gives the same error, the account is not the cause. Continue to Step 4.

4. Check Your Permission Level

What you can do in SharePoint depends on the permission level you hold, and the errors differ with it.

SharePoint has different permission levels that control what you can do:

Permission Level	What You Can Do
Full Control	Everything — manage permissions, delete content, change site settings.
Edit	Add, edit, and delete files and list items. Cannot manage permissions.
Contribute	Add and edit items. May not be able to delete.
Read	View files and pages. Cannot edit, add, or delete.
View Only	View files in the browser. Cannot download.
No Access	Cannot see the site, library, or file at all.

If you can view a file but cannot edit it, you likely have Read or View Only permission. Ask the site owner or IT to upgrade your permission to Edit or Contribute.

If the site or file will not open at all, there is no permission level to upgrade and the block sits on the item itself. Continue to Step 5.

5. Check If the File Has Unique Permissions

SharePoint allows individual files or folders to have different permissions than the library they are in. This is called broken inheritance.

• You may have access to the library but not a specific folder or file within it.
• This is a common cause of "I can see other files but not this one" issues.
• Only the site owner or IT can check and fix this — contact them and specify the exact file or folder you cannot access.

If the whole library is denied rather than one file inside it, unique permissions are not the cause. Continue to Step 6.

6. Check If a Sharing Link Has Expired or Been Revoked

A link that worked last week can stop working without anything changing on your side.

If you received a sharing link and it no longer works:

1. The link may have had an expiration date set by the sender.
2. The sender may have revoked the link.
3. The link type may have been "Specific people" and your email was not included.
4. Ask the sender to re-share the file with a new link, making sure to include your email address. If the new link fails the same way, the block is on the file rather than on the link. Continue to Step 7.

7. Clear Your Browser Cache

Stale browser data can cause persistent access errors even after permissions have been updated.

1. Clear your browser cache and cookies for sharepoint.com and office.com. This signs you out of Microsoft sites in this browser and changes nothing else — no files move and no permissions change. A stale cached sign-in is what makes a site you do have access to say that you do not.
2. See How to Clear Browser Cache and Cookies for browser-specific instructions.
3. After clearing, sign in again and retry accessing the SharePoint resource. If the error survives a fresh sign-in, the checks you can run yourself are finished. Raise a ticket with the exact URL, the error text word for word, and the date your access stopped working.

8. When to Contact IT

Ask for something a site owner can act on in one click. Name the site or library you need and the level of access — Read if you only need to open files, Edit if you need to change them. "I need SharePoint access" will come back to you as a question.

Contact IT if:

• The "Request access" button does not appear or does not work.
• You have confirmed you are signed in with the correct account and still receive errors.
• You need access to a site or library managed by another department.
• You suspect your account was removed from a group (e.g., after changing roles or teams).
• You need access to a site that requires a specific security group membership.

When contacting IT, include:

• The exact URL of the site, library, or file you cannot access.
• The exact error message you see.
• The account you are signed in with.
• Whether you previously had access (and when it stopped working).

Troubleshooting

TIP

The most common cause of SharePoint permission errors is that you are either not a member of the correct M365 Group or SharePoint permission group. Ask the site owner to add you to the site's "Members" group for standard edit access.

Symptom / Error	Potential Cause	Solution
"Access Denied" on the entire site	You are not a member of the site	Click Request access or contact the site owner to be added.
"You need permission to access this item"	File or folder has unique permissions (broken inheritance)	Contact the site owner to check and update permissions on that specific item.
Can view but cannot edit	You have Read or View Only permissions	Ask the site owner to upgrade your permission to Edit or Contribute.
Sharing link stopped working	Link expired or was revoked	Ask the sender to re-share with a new link.
Access works in one browser but not another	Cached credentials from wrong account	Clear browser cache or use an InPrivate/Incognito window.
"Sorry, you can't access this right now" after clicking a Teams Files link	You were removed from the team or the channel is private	Contact the team owner to re-add you, or request access to the private channel.
External guest cannot access shared files	External sharing is disabled or guest was not invited correctly	Contact IT to verify external sharing is enabled and the guest's email matches the invitation.
