One of our users is having difficulty doing a complete search on his emails. When he searches for what he needs, the search seems to only return items on the first few levels of folder hierarchy. Deeper items do not get returned in the search results. The user does have many subfolders - including some that go very deep. These are the ones that are not returned.
We are checking off the 'search subfolders' box. Using Outlook 2010 in an Office 365 environment.
Any help is appreciated.
