I am running Outlook 2011 and noticed today that my search is not pulling any email results dated newer than December 30, 2014.  It will pull calendar related items dated in 2015 but no emails.  I searched the internet and couldn't find any info.  I rebuilt my identity and also attempted to create a new identity which had the same issue.  My co-worker is not having the same issue, so I don't think it is server related.  Not sure what else I can try to attempt to fix this.

OSX 10.10.1

Office version 14.4.7
