Read Only Cloud Evidence Access for Legal Teams

A OneDrive folder can contain the record that matters most in a dispute: revised contracts, a settlement spreadsheet, email exports, scans of signed documents, voice notes, and the working files that explain how a decision was made. But broad cloud access creates an avoidable question from the beginning: who could change the source material, and how?

Read only cloud evidence access addresses that operational concern by limiting a connected review platform to viewing and importing materials from the designated folder. For legal teams, the value is not merely convenience. It is a clearer separation between the original cloud repository and the case used to organize facts, review content, and trace a finding back to its source.

What read only cloud evidence access means

Read only access means the connected service can retrieve material from an authorized OneDrive folder without permission to edit, move, rename, or delete files in that folder. The underlying OneDrive remains under the control of its owner and the organization’s own access policies.

That distinction matters in an evidence workflow. A litigation team may need to review a folder maintained by a client, custodian, investigator, or internal business unit. The review environment should not become another party capable of altering the live source. A read only connection keeps the system’s role focused on intake and analysis.

It is also necessary to be precise about what read only access does not do. It does not determine whether a file is authentic, establish legal custody, or resolve questions about a custodian’s collection process. It does not prevent a person with separate OneDrive permissions from modifying material directly in OneDrive. Those questions require the legal team’s own preservation, collection, and evidentiary procedures.

Why the permission model matters during fact development

Cloud folders are rarely neat production sets. A single matter may include a mix of native Word documents, scanned PDF exhibits, Excel workbooks, PowerPoint presentations, text files, recordings, and photographs. A folder may also reflect a business process in motion, with drafts, duplicates, versions, and documents that have not yet been reviewed for relevance.

Giving a review tool write access to that repository introduces risk without helping the factual task. The team needs to locate, read, compare, and cite material. It does not need the analysis system to reorganize the client’s OneDrive folder or overwrite a source file.

Read only cloud evidence access also helps establish disciplined roles. The information owner manages the cloud repository. The legal team controls the scope of its review. The analysis platform processes the material available through the authorized connection. Keeping those roles distinct makes it easier to explain the workflow internally and to investigate a question about where a document came from.

Consider a commercial dispute involving a disputed change order. The relevant OneDrive folder includes a signed contract PDF, a later Word draft, an Excel cost schedule, and a series of meeting recordings. The central question may be factual: when did the scope change, who received the revised terms, and what did the recordings say about approval? A read only connection allows the team to examine those materials while leaving the cloud source untouched by the review process.

Preserve the source, then make it searchable

A folder connection alone does not make a large record usable. Legal teams need a way to move from a broad question to the supporting passage, page, message, or recording moment.

TranscriptMe imports WhatsApp exports, mailboxes, OneDrive folders and loose files, with OneDrive access limited to read only permission, and organizes the imported material within a case. On arrival, each file receives a SHA-256 hash. The case is isolated in the database, and data is encrypted in transit. In general practice, a careful intake process keeps the task focused on source based fact review.

The platform reads PDFs, including scanned PDFs through OCR, along with Word, Excel, PowerPoint, and text files. On paid plans, it transcribes Portuguese audio and video, and English when the English runs two seconds or longer, while shorter English passages come out translated into Portuguese, and it creates AI descriptions of photos and videos. A photograph of a deed, for example, may be described as showing a signed document on a desk. That description is not OCR of the photograph and should not be treated as extracted document text.

Once sources are organized in a searchable case, a reviewer can ask a natural language question such as: “Where is the deadline for written notice?” or “What did the project manager say about approval in the May recordings?” The answer should return with the relevant source and location, such as a PDF page, a Word or spreadsheet section, a message, or the second of an audio or video recording.

That citation is the working unit of review. It lets the lawyer return to the original context, compare language, assess ambiguity, and decide whether the fact matters to the case theory. The platform organizes facts. The lawyer makes the legal judgment.

Scope is as important as permission

Read only status is useful only when access is deliberately scoped. Before connecting a cloud folder, identify which repository is appropriate for the matter and whether it contains material outside the intended review set. A department wide folder, for example, may include unrelated personnel, financial, or privileged material. Read only permission does not make an overly broad collection narrow.

A practical approach starts with the case question. If the issue concerns a particular transaction, project, policy period, or custodian group, use a folder structure that reflects that boundary where possible. Confirm who controls the OneDrive location, who is authorized to grant access, and whether the folder contains links or copies that need separate treatment.

The team should also understand the timing of the connection. A file in a cloud folder may be revised outside the review platform after it has been made available. The SHA-256 hash recorded at arrival identifies the file received at that point. If a later version becomes relevant, the legal team should evaluate it as a separate factual development rather than assuming that all similarly named files are identical.

This is particularly relevant with working documents. A contract folder may contain “Final,” “Final 2,” and “Final signed” versions. A search can surface language across those files, but the legal significance of each version depends on context, authority, delivery, and the surrounding record. Technology can identify the language and its source. It cannot determine which draft created an obligation.

A workflow for cloud folder review

The strongest use of a read only connection is deliberate, not automatic. Start by documenting the folder selected for review and the person or team that authorized access. Confirm that the access level is read only and that the connection is limited to the intended OneDrive location.

Next, review the incoming record as a collection rather than as isolated files. Search for names, dates, project terms, account references, or recurring phrases. Use the results to build a chronology that connects a message thread, an attachment, a revised document, and a recording. When a fact appears important, open the cited source location and read the surrounding context.

For example, an employment matter may include a manager’s email mailbox, a OneDrive folder with policy documents and investigation notes, and WhatsApp exports containing contemporaneous messages. The factual record may show that a policy was circulated on one date, discussed in messages later, and referenced during an audio meeting. Each item should be reviewed on its own terms, with the cited source available for verification.

Finally, distinguish the factual output from legal conclusions. “The email states that the notice was sent on June 4” is a traceable factual proposition. Whether that notice met a contractual, statutory, or procedural requirement is a legal analysis for counsel. Maintaining that distinction keeps the review record accurate and the legal work where it belongs.

Questions to ask before connecting OneDrive

Before granting read only cloud evidence access, legal teams should ask whether the folder is the right source, whether its owner has authority to authorize access, and whether the scope is proportionate to the matter. They should also identify whether files may change during review and decide how the team will account for later versions.

Security questions should be concrete. Who can access the case? Is the case separated from other matters? What happens to the file on intake? Can a reviewer return from a generated answer to the supporting passage or recording time? Specific answers are more useful than general claims about AI.

The goal is not to treat a cloud connection as a substitute for evidence management. It is to create a controlled path from an authorized repository to organized, source cited facts. When the folder is scoped carefully and the source remains distinct from the case used for review, the team can spend its attention where it belongs: reading the record, testing the chronology, and applying professional judgment to what the facts mean.
