it’s nigh on 3 months old – but it lists some of the issues with Exchange 2013 RTM.
Prior to finding this article – I hadn’t been able to find any list of issues with the release, but my own list of issues was growing.
Exchange 2013 release seems to have been rushed a little, but lets hope that these issues are addressed by CU1 (which is due anytime now) – and I’m really hoping the EMC makes it back in by SP1 (but I doubt it!)
