Installation guide
Follow the steps below to connect Microsoft 365 to Scribe.
Install Scribe Add-in
Get the Scribe Add-in from the Microsoft App Source
In the Microsoft App Source, click "Get it now"
Select your Microsoft 365 account
You'll be redirected to your Microsoft 365 admin dashboard. If redirected to Outlook Inbox instead, you're not a global admin and the add-in won't work.
Select "Entire organization"
Choose which users get the add-in. Select "Entire organization" unless you want to test with a small group first then click "Next"
Grant permissions
Accept the permissions in the popup that opens.
Click next
After granting permissions, click "Next"
Click on "Finish deployment"
The add-in will now be deployed in your Microsoft 365 account and across all Outlook instances for your users.
In Scribe, confirm the add-in validation by clicking "Yes I installed it"
Wait for Microsoft validation
Microsoft can take up to 72 hours to install the Scribe Add-in across your organization. You will be notified by email when it's done. If the validation is too long, make sure to check the troubleshooting list in the modal.
Scribe Scribe Add-in installed
Once you get the validation modal, click "Install signature" to go to your Scribe signatures list.

FAQ
Your Microsoft 365 integration questions answered
No. Scribe installs signatures centrally for every Microsoft 365 user you assign, and teammates see their signature when composing emails.
The Microsoft 365 integration installs signatures for Web, Desktop, iOS, and Android. To cover every other client and device, including Apple Mail, use the server-side Microsoft 365 integration on its own or together with this one.
No. The Microsoft 365 integration is cloud-based: the signature lives in each user's Microsoft 365 account and your emails stay within your email provider. Scribe is SOC 2 Type II certified.
Publish the change in Scribe and it is pushed to every assigned Microsoft 365 user automatically; there is nothing to reinstall. Smart fields keep names, job titles and phone numbers up to date.
Connecting takes a few minutes, but Microsoft can take up to 72 hours to roll the Scribe add-in out across your organization.
Yes. Connect the Scribe MCP server to Claude, ChatGPT, Cursor or another AI assistant and it can walk you through this guide, create and assign signatures, and check that the installation went through. Authorizing Microsoft 365 itself (admin consent, OAuth or an API key) has to be done by you, in your browser: an AI agent cannot grant that access on your behalf. See scribe-mail.com/ai-agents.
