After a recent update my S4 stopped connecting to our company's exchange server. My IT department is telling me that this issue is affecting others with the Galaxy S4 after the latest update. Has anyone else come across this issue (several attempts at Googling this issue came up dry)? It seems to be exclusively the Galaxy S4 (Note 3, Galaxy Nexus, and S3 all connect fine), and only those that upgraded the software to the latest version.
