Hi All,

I have 2 new users who when they try searching for items in a shared mailbox which has existed for many years can only see results appear from their start date onwards. Is this normal behaviour for Outlook? Is there a way to change the search results so that all historical results are found. The mailbox is not archived and version is Office Outlook for Office 365 (16.0.11727.20222) 64bit.



Thanks.

Look in their File > Options > Search

There's a choice there "Improve search speed by limiting the number of results shown" which might be the cause.

The Troubleshooter when you click the 'Indexing Options…' button might help.

Thank you @Lugh but unfortunately this did not solve the issue. Good shout though I hadn't tried that.

To anyone who finds this post with the same issue - this was resolved by turning off Cached Exchange Mode

Thanks for reporting back, that's helpful
