I have a user whose sent mail briefly appears in her sent folder, but quickly moves to her local failures folder. It appears these messages actually do get sent. When I open her account in OWA, the mail is not showing in her sent folder either. My other 7 users aren't having any problem. This user also reports that when she deletes mail from Outlook, it still shows up on her iPhone 5. We run Exchange 2010 SP 1.
Do you think I should run scanost.exe, and then maybe force an ost file rebuild?
Thanks so much!
