title: Outlook API Filter by Subject line only returns 275 results
body: <p>We have been having issues with the Outlook Mail API for a while now. There was a known bug where filtering by subject line would not return results and it was fixed.</p>
  
  <p>We tried our implementation again, but are capped at 275 results every time. Below is an example of the code/query that we are running and you can see that the first 2 pages have nextLink for the next page but the third page stops at 75 results with no nextLink. We tested this on multiple accounts (all with 30,000+ emails) and different subject line queries and get 275 results every time.</p>
  
  <pre><code>search emails that contain 'a' in the subject
