list-supported-languages
Retrieves the list of locales and languages supported on a user's mailbox server. Validate a locale value before updating the user's preferred language.
Instructions
Get the list of locales and languages that are supported for the user, as configured on the user's mailbox server. When setting up an Outlook client, the user selects the preferred language from this supported list. You can subsequently get the preferred language by getting the user's mailbox settings.
đź’ˇ TIP: Lists locales and languages the user's mailbox server supports for the Outlook UI and message rendering. Returns localeInfo objects with locale (e.g. 'en-US') and displayName ('English (United States)'). Use this to validate the locale value before calling update-mailbox-settings to change the user's preferred language.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| top | No | Page size (Graph $top). Start small (e.g. 5–15) so responses fit the model context; raise only if needed. Use $select to return fewer fields per item. For more rows, use @odata.nextLink from the response instead of a very large $top. | |
| skip | No | Items to skip for pagination. Not supported with $search. | |
| search | No | KQL search query — wrap value in double quotes. Cannot combine with $filter. | |
| filter | No | OData filter expression. Add $count=true for advanced filters (flag/flagStatus, contains()). Cannot combine with $search. | |
| count | No | Set true to enable advanced query mode (ConsistencyLevel: eventual). Required for complex $filter on flag/flagStatus or contains(). | |
| fetchAllPages | No | Follow @odata.nextLink and merge up to 100 pages into one response. Can return enormous payloads—only when the user explicitly needs a full export. Prefer a small $top first, then paginate or narrow with $filter/$search. | |
| includeHeaders | No | Include response headers (including ETag) in the response metadata | |
| excludeResponse | No | Exclude the full response body and only return success or failure indication |
