Hello,

Note: I put this question here because these issues only started happening after we migrated to Exchange 2013

We have an issue with outlook and mobile devices that appeared after we upgraded out exchange server from 07 to 13. in a nut shell our mobile devices (iPhones) seem to take for ever to open an email, emails no longer get categorized in threads properly, contacts disappear randomly and then re-download as does all mail messages. In the Outlook 2013 messages just don't seem to stay organized in conversations even though the option is checked. Has anyone else experienced these issues or something similar? Any advice on how to explain and correct, adjust, modify this new behavior would be greatly appreciated.

Thanks you,
