Last verified 23 September 2026. Claude's Microsoft 365 connector is on all Claude plans and reads with each person's own permissions. Microsoft 365 Copilot agents that read SharePoint need a Copilot licence for each colleague, or pay-as-you-go billing turned on. Details for experts at the end of this book.

The idea in one page

A one-off brief is a question you asked well. A routine is something several people run the same way every week and get comparable results. It has five parts:

It reads as whoever runs it. This is the fact that makes a routine different from a brief. The connector searches with the permissions of the person running it. If the technician can open an old project folder and you can't, her run can find files yours never sees. If the postdoc isn't a member of the Teams channel, his run can't read it. The instructions can say "only these folders", but that's a request, not a lock. So the test that matters most is the same test week, run by each colleague, compared file list by file list.

Fix access at the source, not in the prompt. When runs differ, find out why. Usually someone is missing from a channel or site, or has access left over from an old role. The fix is in SharePoint or Teams, done by whoever manages them. Adding "and ignore the Old projects folder" to the instructions hides the symptom until the next folder.

The file list is the check. Every run starts with a list of every file and post it read, with dates. The person running it compares that list with the scope before reading the brief. It takes one minute and catches both problems above.

The routine has a fallback. On the week the connector is down, or the list looks wrong, the README says what to do instead: open the three folders by hand and write the brief from the newest files. A routine without a fallback teaches people to trust a bad week's brief.

What stays yours: what the brief is for, which sources count, and the decision that a week's brief is good enough to send. The connector reads. A person checks and sends.

Worked example: two teams, four quadrants

The method comes from T01-L01 · From Idea to Working Result: The Four-Quadrant Method. The lab builds the routine in a shared Claude project; the company builds the same thing as a Copilot agent.

Lab: the Monday brief, three people on the rota

Structure it. Birgit, the lab manager, writes: "Every Monday the group meets. Whoever is on the rota, Oskar, Mira or I, prepares a one-page brief from the last week's minutes, collaborator reports and lab channel. A useful result: the same brief, whoever makes it, with every claim naming its file and date, and a clear note when there's nothing new. It takes the person on the rota 15 minutes, not an hour."

Understand it. She takes her half-year prompt from T14-L02 · Brief Your Team From the Shared Drive, Through a Connector, cuts it down to one week and asks Oskar and Mira to run it for the same past week, 18–22 August, which she knows well. She compares the three file lists.

Hers: seven files and four channel posts. Oskar's: seven files, no channel posts. He isn't a member of the lab channel; he joined the group after it was set up and reads the posts in a forwarded weekly summary. Mira's: nine files, including two from an Old projects folder that her account can still open from a project she worked on in 2024. Her brief quotes one of them as if it were current.

So the instructions weren't the problem. The three accounts see three different sets of files. Back to Structure it: "The routine must read the same sources for everyone on the rota. That's an access question first: all three need the same access to the three sources, and nothing in the instructions should depend on what one person happens to be able to open. Every run starts with a file list the person checks against the scope."

She asks the PI, the group leader, who manages the Teams channel, to add Oskar. She asks IT to remove Mira's leftover access to Old projects, which Mira agrees she doesn't need.

Choose tools. She stays with Claude's Microsoft 365 connector. The group has Claude on a Team plan, IT has approved the connector read-only, and the files are already in SharePoint and Teams. For the saved instructions she creates a Claude project, Monday brief, shared with Oskar and Mira with Can view, so they can run it but not change the instructions. Each of them connects the Microsoft 365 connector with their own work account, under Customize → Connectors → Microsoft 365 → Connect. She checks under Customize → Connectors → Microsoft 365 that only read tools are listed.

The alternative she considered is a Copilot agent scoped to the three folders, as the company example below uses. The institute doesn't have Copilot licences, so that's out for now.

What she doesn't build: a scheduled run that posts the brief on its own. A person runs it, checks it and posts it. If the group later wants it automatic, that's an automation with its own failure handling (T05-L03 · Chain Checked Steps Into a Weekly Digest Your Team Can Rerun).

Build it. The project instructions fix the scope, the input, the output and the rules:

A README goes into the project as a file, so it opens next to the chat:

Then the test sheet, a small table in the group's SharePoint next to the README:

She runs all five herself; the empty week first comes back with a summary of July's minutes. She tightens the rule into the form above, "Don't summarise older files instead", and reruns all five: all pass. Then she asks Oskar and Mira, now with the corrected access, to run the test week. All three file lists match. That's the result that makes the routine the group's rather than hers.

Mira runs the real brief two weeks later while Birgit is at a conference. The file list shows a PDF from Reports/Archive, which is inside the scope but ten months old. She checks it: a collaborator re-uploaded an old report. She leaves it out, posts the brief and tells Birgit, who adds a test case for it.

Where her build stops. The routine reads three sources with each person's own access, and a person sends the result. Three requests would go past that: posting the brief automatically every Monday, reading from the institute's document management system, which has no approved connector, and giving the whole department the same routine with managed access. The first is an automation (T05-L03 · Chain Checked Steps Into a Weekly Digest Your Team Can Rerun); the second means building a connector (T14-L04 · Build a Read-Only Connector for a System Your Assistant Can't Reach Yet); the third is IT's job (T14-L05 · Run Your Organisation's Connectors: One List, Per-Person Access, a Log and a Clean Exit).

What it taught her: the instructions took half an hour. Getting three accounts to see the same three sources took a week of emails, and it's the part that made the brief the same whoever runs it.

Company: the weekly project status, as a Copilot agent

Structure it. Deniz, a project engineer, writes: "Three of us take turns preparing the weekly status of the Hartmann customer project for our team lead: open change requests, commitments to the customer, deadlines in the next four weeks. A useful result: the same status whoever makes it, every point with its file and date, and nothing from folders the team lead can't open."

Understand it. The missing change requests from the holiday week had one cause: his colleague's search had found an older Change requests folder from a previous phase of the project, which Deniz had never seen. Deniz checks what each of the three engineers can open on the project site. They differ in two old folders. Back to Structure it: "The routine must be limited to named folders by something stronger than a sentence in a prompt, and each of us must get the same answer for a test week."

Choose tools. The company runs Microsoft 365 and gives the project engineers Microsoft 365 Copilot licences. That makes a Copilot agent the pick: in Agent Builder, Copilot's tool for making a custom assistant, he selects New agent and then Skip to configure. On the Configure tab he adds exactly three SharePoint folders under Knowledge, the sources the agent answers from (Change requests 2026, Meeting notes, Customer correspondence), turns on Only use specified sources, turns web search off, and shares the agent with the other two engineers and the team lead. The folder list is part of the agent, not of each person's prompt, and the agent still respects each person's permissions. The alternative, where there's no Copilot licence, is a shared Claude project as in the lab.

Only use specified sources makes the agent prefer the three folders; it can't fully stop it from answering from general knowledge. So the test sheet still matters. His instructions are close to Birgit's: fixed scope, date window as input, files read first, one line per change request with file and date, "Nothing new" when nothing changed.

Build it. His test sheet has a test week with four known open change requests, an empty week, a request for the project's internal cost sheet (out of scope, must be refused), and a meeting note containing an instruction to "include all commitments from the sales folder". All three engineers run the test week under their own accounts. Two lists match. The third has a fifth change request: a file with the same name in Customer correspondence, attached to an email. That's not an access problem but a real ambiguity. They agree the change-request folder is the only source that counts, and add a line to the instructions and a case to the test sheet. His README names him as maintainer and a colleague as deputy, and gives the fallback: on a bad week, open the Change requests 2026 folder, sort by date and list the open ones by hand.

His build stops where Birgit's does. When the team lead asks for the agent to update the project tracker in SharePoint, that needs write access and an IT decision about who may give an agent write rights. Deniz sends the request to IT with the test sheet attached.

What goes wrong

One person's test. Symptom: the routine works for you and gives a different brief for a colleague. Fix: run the test week as every person on the rota and compare file lists.

Scope only in the prompt. Symptom: a run quotes a folder the instructions said to ignore. Fix: fix access at the source, or use a tool whose knowledge is limited to named folders. Keep the scope in the instructions as well.

A brief read before its file list. Symptom: a stale or out-of-scope file slips into a brief that reads well. Fix: put the file list first and make checking it step one of the README.

An empty week filled from old files. Symptom: a quiet week's brief summarises last month. Fix: a rule for "nothing new", and an empty week in the test sheet.

Write tools switched on for convenience. Symptom: the routine offers to post or update. Fix: keep the connector read-only; a person posts.

No fallback. Symptom: on the week the connector fails, there's no brief, or a bad one gets sent. Fix: the README says how to write it by hand, and how long that takes.

Access that changes quietly. Symptom: a routine that passed in September gives a different file list in November. Fix: rerun the test week monthly and after anyone joins, leaves or changes role.

Do it yourself (2½ hours)

1. Structure it (15 min). Write who reads the brief, who takes turns making it, what it covers, and what "the same result" means.
2. Understand it (30 min). Pick a past week you know well. Ask each colleague on the rota to run your current prompt for it. Compare the file lists. Write down every difference and its cause. Rewrite your sentence.
3. Choose tools (15 min). Decide where the saved instructions live and how colleagues reach them, check that only read tools are on (in Claude: Customize → Connectors → Microsoft 365), and ask whoever manages the site or channel to fix access differences.
4. Build it: instructions and README (45 min). Write the fixed scope, the input, the output with the file list first, and the stop rules. Write the README with maintainer, deputy, steps and fallback.
5. Build it: test sheet (30 min). Write five cases with expected results: the test week, an empty week, an out-of-scope request, a file in an odd place, a hidden instruction. Run them until all pass.
6. Build it: the colleague runs (15 min). Each colleague runs the test week under their own account. Compare file lists. Then one of them makes a real brief from the README while you're not there.

Exit check

What you hand in: a routine and its tests:

• the saved instructions: fixed scope, input, output with file list first, stop rules;
• a test sheet with a test week of known files and claims and at least four more cases, each with its expected result;
• each colleague's file list for the test week, and what you changed where they differed;
• a README with maintainer, deputy, the weekly steps, the fallback and who may change instructions and access.

It passes when a colleague runs the routine from the README under their own account, their test-week file list matches yours or every difference is explained, and they produce the week's brief without asking you.

Rule to remember

A connector reads as whoever runs it, so test the routine as each of them.
