Consider an employee who finds an AI assistant that can summarize long email threads and draft replies. The demonstration looks useful. Then the tool asks to connect to the employee’s business mailbox.
That connection deserves a separate decision. A mailbox may contain client records, invoices, personnel discussions, and password reset messages. Before approving an AI email tool, find out what it can read, what it can change, where the information goes, and how access ends. Those answers determine whether a convenient feature fits your business.
Start with the job you need done
“Help with email” is too broad to approve safely. Write down a specific task, such as preparing a draft response to routine appointment requests. Identify the people who need it and the information involved.
A useful first test is whether the task needs a live mailbox connection at all. For an occasional writing task, an approved tool may work with a short passage that has been cleared for sharing. That still requires a data handling decision, but it avoids granting continuing mailbox access just to test a feature.
For a recurring workflow, define success before connecting anything. Will the tool save meaningful time? Who checks its output? What mistake would be unacceptable? A tax practice might allow help with scheduling while keeping tax records outside the pilot. A law firm might begin with administrative messages rather than matter correspondence.
These boundaries give the technology review a business purpose. They also make it easier to decline permissions that do not match the task.
Read the permission request as a list of capabilities
Connecting an application commonly involves OAuth, a system that lets software receive permission without being given the employee’s password. That does not make every permission appropriate. Microsoft’s overview of application permissions explains why applications should receive only the access they need.
For Microsoft 365, the Microsoft Graph permissions reference distinguishes access to read messages, create or change messages, and send mail. Mail.ReadWrite does not itself include permission to send. Mail.Send is a separate capability. Access to shared mailboxes also needs attention.
There is another important distinction. Delegated permissions operate on behalf of a signed-in user. Application permissions can operate without a signed-in user and may reach multiple mailboxes unless properly restricted. Ask your IT provider to verify the actual permission type and effective scope rather than judging by the consent screen’s headline.
For a tool that only summarizes messages, permission to send email should prompt a specific explanation. For a pilot involving one department, broad access across the organization should trigger a discussion about narrower options. If the vendor cannot explain why the requested access is necessary, pause the connection.
Review what happens beyond Microsoft 365
Mailbox permission and vendor data handling are different questions. An application might be permitted to read a message and then process or retain information in another service. Your existing Microsoft 365 settings do not answer every question about that separate copy.
Ask the vendor for written answers about retention, deletion, model training, and administrator controls. Find out which other companies it uses to process your data. Establish which contract and product tier govern the service. Do not assume that a consumer account and a business subscription have the same terms, or that every product labeled “Copilot” follows identical arrangements.
For sensitive work, include the person responsible for confidentiality or compliance before approval. Patient information, legal correspondence, and financial records can introduce obligations that a general productivity review will miss.
One practical test is to ask where an example message would travel. Who receives its contents? Is the original stored, or only a generated summary? Can the firm request deletion? An answer that consists only of “we use encryption” leaves those business questions unresolved.
Treat incoming messages as untrusted material
An AI assistant reads words and generates a response. Some connected tools can also take actions. That creates a reason to examine how they handle instructions embedded in messages.
Microsoft’s guidance on indirect prompt injection describes attacks in which malicious instructions appear inside external content such as email or documents. The AI may mistake that content for a command. This is a risk to evaluate, not a claim that every assistant will follow every malicious message.
Consider a hypothetical invoice email containing text that tells an assistant to forward earlier correspondence to another address. A well controlled workflow should treat that text as message content, prevent unauthorized actions, and give the business a way to investigate unusual behavior.
For an initial rollout, prefer drafts that a person reviews. Require separate verification for changes to payment details. Reviewers should check recipients, attachments, factual claims, and commitments before sending. Human review needs to be an actual step in the workflow, with a named owner and enough time to do it.
Run a pilot with clear approval conditions
Begin with a small group and the least sensitive suitable workflow. Keep a short record containing the application name, business owner, approved purpose, permission scope, data restrictions, and review date. Add the person responsible for removing access.
Ask IT to review consent controls before employees begin connecting tools independently. Microsoft documents app consent policies, but the right policy depends on your environment and business needs. Changes should be planned so legitimate applications keep working.
During the pilot, compare real time savings with the effort needed to check results. Record incorrect summaries and attempted actions outside the approved task. A tool that saves five minutes drafting but requires extensive checking may need a narrower assignment.
Set a date to decide whether to expand, adjust, or stop. Avoid leaving a temporary trial connected simply because nobody owns the next decision.
Test how you will disconnect it
Before wider adoption, ask IT to demonstrate the exit procedure. Microsoft provides guidance for reviewing and revoking application permissions. Removing an app from a browser or ending its subscription should not be your only evidence that mailbox access has ended.
Treat access removal and vendor deletion as separate tasks. Revoking permission does not retrieve information already copied into another system. Ask for the vendor’s deletion process, any retention exceptions, and the evidence available after the request.
Include connected applications in employee departures and vendor reviews. A mailbox integration should have an owner even after the person who first discovered it leaves.
Make the connection an informed business decision
Before approving an AI email tool, ask your IT provider to explain its access in plain language and show how the approved boundaries will be maintained. A useful answer connects the permissions to a specific task, identifies the data involved, and includes a tested way to stop using the service.
