We have a stable SBS2011 installation with 5 users utilising Exchange 2010, Outlook 2013, and recent model iPhones. Several days ago one of the users (of course it was the company owner!) reported that his iphone was not recieving new emails but his iPad was. I suggested re-entering his email password on his iphone as a reboot had not worked. This got the iPhone working again but a fault has been discovered.
Contacts that previously had only the users first name in the First Name field have adopted the Last Name of the next Contact. For example there was a Barbara and a Barbara Smith. The first Barbara now has Smith as a Last Name. Barbara Smith's email address is now appearing in Barbara's contact in the Email2 Field.
My google-fu may be letting me down, but I cannot see any more references to this happening, and therefore have no insight from others as to how this might have occurred and how it might be prevented in future. This user has 3 different Windows computers he uses running Outlook 2013, but they don't seem to have contributed to this.
Thanks in advance for any thoughts/suggestions.
