AI Studio ships the logos of the AI providers it supports and shows them next to the matching provider entry, so you can see at a glance which service a provider connects to. All product names, logos, and trademarks are the property of their respective owners. Their use here identifies compatible services and implies no endorsement, sponsorship, or business relationship between MindWork AI Studio and these companies.
-Some of these logos come from the [Simple Icons](https://github.com/simple-icons/simple-icons) project, which publishes them under [CC0-1.0](https://github.com/simple-icons/simple-icons/blob/16.21.0/LICENSE.md); the trademarks themselves are not part of that release. The remaining ones were taken from the official brand resources of the respective provider. The source of every single file is documented in [the provider icon notes](app/MindWork%20AI%20Studio/wwwroot/images/provider-icons/README.md). All logos ship with AI Studio and are loaded from your device, so showing one never sends a request to the provider.

# v26.9.1, build 256 (2026-09-xx xx:xx UTC)
+- Added Outlook Mail for company Exchange on Windows. After your organization sets its Exchange address, you can ask a trusted model to search and read messages in your primary mailbox without opening Outlook or entering a password. The tool does not read attachments or shared mailboxes.
- Added tools that AI models can use on their own, starting with Web Search and Read Web Page. When you ask something a model cannot answer from what it knows, it now searches the web, reads the pages it found, and answers with the sources it used. You decide which tools a model may use, right below the message field, and you can watch it work: AI Studio shows which tool is running and, afterward, every call it made with its result. Whether tools are offered at all depends on the model because it has to support them. Read Web Page works right away; for Web Search you pick a search service in the app settings — Tavily or Staan with a free API key, or a SearXNG instance you run yourself. Set up more than one, and they can take turns when one of them finds nothing, or be asked all at once with their results combined. Many thanks to Peer Schütt (`peerschuett`) and Nils Kruthoff (`nilskruthoff`) for building this feature.
- Added answers that appear word by word even while the AI uses its tools. You read along as the model writes, including the short note it puts down before it looks something up, and the answer that follows a tool call arrives the same way instead of all at once at the end.
- Added safeguards around everything these tools bring back. Anything fetched from the web is treated as untrusted: AI Studio removes instructions hidden in a page before a model reads it and tells you when it did, exactly as it already does for the documents and web pages you load yourself. A model can never point a tool at your own network. Each tool states how much you have to trust a provider before it may be used with it, so your questions do not travel further than you allow. You can adjust that requirement per tool in the app settings.

A setting offering a fixed choice takes it from an option source — `RequiredChoice` and `OptionalChoice` name a list the app maintains, see `ToolSettingsOptionSources` — or spells its values out in the field's `enum` list, which is how a definition arriving as data offers a choice of its own. The two are mutually exclusive, and `ToolRegistry` rejects a definition that uses both or names an unknown source. Check a stored value in `ValidateConfigurationAsync` either way: it can predate the current list or arrive from an organization's configuration.

Every successfully retrieved page with readable content is also returned as a structured tool source, using the final URL after redirects and the extracted page title. The provider collects these sources across local tool calls and attaches them to the final response under the separate “Sources used by tools” heading. Failed, blocked, empty, and duplicate retrievals do not add sources — a pattern worth copying for any tool that returns material the user may want to check.
+## Outlook Mail
+
+`outlook_mail` is a Windows-only tool for the signed-in employee's primary Exchange mailbox. It requires an HTTPS EWS endpoint ending in `/EWS/Exchange.asmx` and uses Windows integrated authentication. The optional Outlook Web URL is only used to build links when Exchange supplies a message path. Search enumerates folders below `msgfolderroot` and searches each with `FindItem`; read uses `GetItem` and checks the returned parent folder against that enumeration. Folder and result limits can make a search partial. No mailbox address, password, or attachment content is accepted or fetched.
+
+The tool accepts a High-confidence or organization-trusted provider for a call, independently of the adjustable tool confidence setting. Search terms and message IDs are redacted from traces, and mail results are omitted from the trace while still returned to the model. Every mail field returned to the model goes through `PromptInjectionGuardService`. A successful call marks the chat as requiring High confidence; a configuration-trusted provider below High therefore cannot continue that chat under the current chat confidence rule.
