A Microsoft 365 worker shares a OneDrive, SharePoint, Teams, or Outlook cloud attachment link and assumes the recipient can open it. Instead, the recipient lands on Access Denied or Request Access.
If you're unfamiliar with this industry, start here.
Microsoft 365 file links are permission-bearing objects. The same file can be shared through OneDrive, SharePoint, Teams, or Outlook, and the chosen link type determines who can open it.

The Reality
Microsoft 365 coordinator, project lead, team administrator, or knowledge worker

I send the file before the morning meeting because I want everyone to review the same document. I use the Share button, copy the link, paste it into Outlook or Teams, and move on because it looks like the normal Microsoft 365 way to share.
Ten minutes later someone replies, "I need access." Then another person does the same. One colleague can open it from SharePoint, but not from the Outlook link. Another is signed into a different Microsoft account. I check the link settings, but the wording does not make it obvious whether I created a link for specific people, people in the organisation, existing access, or just the recipients of the message.
I manage to get one person in by sending a new link, so the day is not a total loss. But now I do not trust the original link, I do not know who has access, and I have to stop the work to become the permission helpdesk.
By the end of the day, the file has been resent, someone has asked whether I saw their access request, and the discussion has moved on without everyone reading the document. I want a simple pre-send check that tells me who can open the link, which account they need, and whether I should use a different sharing option before I hit send.

We traced backward through five layers of "why" until we hit the source. Here's what's really driving this.
Why does the recipient hit Request Access?
The link does not grant access to that recipient in that context.
Why did the sender expect access to work?
The sender assumes sharing a link means file permissions, link permissions, and recipient identity all line up.
Why is that assumption fragile?
Microsoft 365 has multiple link scopes and storage surfaces, including OneDrive, SharePoint, Teams, and Outlook cloud attachments.
Why can the worker not resolve it quickly?
The UI exposes sharing through several surfaces, and the sender may not know whether they copied a direct URL, scoped link, or existing-access link.
Why does it persist?
Teams and OneDrive make sharing easy enough to do quickly but not always clear enough to predict recipient access.
Root Cause
Microsoft 365 sharing links look like ordinary URLs, but they behave like permission objects. Non-admin users often do not see the difference between link type, direct access, site/library membership, guest authentication, and the account the recipient is signed into.

Microsoft explains the permission model, but normal users need a small pre-send workflow that prevents Request Access loops.
