 ## Contact search does not show expected results

-It seems that \[MS-DLX\] `SearchOn` feature is broken, at least for some Office365 accounts. The server only returns 0 or 1 results, even if there should be more matches. Also partial matches do not work.
+It seems that [\[MS-DLX\]](https://msdn.microsoft.com/en-us/library/cc431520.aspx) `SearchOn` feature is broken, at least for some Office365 accounts. The server only returns 0 or 1 results, even if there should be more matches. Also partial matches do not work.

 The only known workaround is to enter a partial name. That will trigger a retry with a search over all attributes, which isn't as exact and will return too many results.
