Hi,
With v5.0, messages *I know* are in Outlook are not returning when I search for them.
I have the system indexed nightly, and "options" tells me that the system was indexed over night and the messages in questions are a few weeks old, so it's not a matter of searching for them before an index was done.
(I've just switched so that indexing is every so-many minutes.)
Nevertheless, I never had this problem with 4.x
