Why Teams Replace Attachments With Share Links

Email is where governed file exchange quietly leaks. Contracts, reports, and client files go out as attachments: uncontrolled, unrecallable, capped by the mail server, and invisible to the audit trail. The add-in fixes that at the point of send, in the tool people already live in.

Revoke A File After You Hit Send

An attachment is gone the moment the email leaves. A Share Link stays under your control. Sent the wrong version, or sent it to the wrong person? Revoke the link and the file is unreachable. No attachment has ever been able to do that.

No More "File Too Large" Bounces

Mail servers cap attachments around 25 MB. The add-in uploads the file to Files.com and sends a link instead, so a 5 GB video or a full project archive goes out in the same email as a contract. The recipient downloads it in their browser, no account needed.

Your Sharing Policies Apply Automatically

Every link the add-in creates follows your site's Share Link policies: password protection, expiration, recipient restrictions. The sender doesn't configure anything, and can't skip anything. Governance rides along on every email.

Every Send Lands In The Audit Trail

Attachments vanish into sent-mail folders. Share Links are recorded in the Files.com audit log: who sent what, who downloaded it, and when. When someone asks “did the client ever get that file,” the answer is a lookup, not a guess.

How It Works In The Compose Window

Attach With Files.com

Pick local files from the compose window. The add-in uploads them to Files.com, creates a Share Link, and inserts it into your message body. Nothing about how you write the email changes.

Convert Existing Attachments

Already dropped files onto the message? One click converts the attachments into a Share Link: same email, same recipients, none of the attachment risk.

Installs With The Desktop App

The add-in ships inside the Files.com Desktop App for Windows. There's no separate download and no per-seat add-in deployment. Install the Desktop App, sign in, and the buttons appear in the Outlook compose toolbar.

Built For The Files People Actually Email

Contracts to clients. Board reports to stakeholders. Deliverables too large for the mail server. Sensitive documents to outside counsel. These are exactly the files that have no business riding along as attachments, and exactly the ones that always do, because sharing any other way means leaving the email.

The add-in creates snapshot Share Links, so the file you send is the file they get: a fixed copy, held by Files.com, downloadable until the link expires or you revoke it. Set an expiration or a download limit and the sent copy cleans itself up when its job is done. No stale file sits in someone's inbox forever. Every link can carry your branding and your domain, so what the client clicks looks like you, not a third-party tool.

Files.com's strengths are simplicity, ease of use, and the cloud connectors. We don't have to invent custom infrastructure for every partner.
