This has happened to me a few times now and I'm starting to get really annoyed with it!

I have the Samsung Galaxy S3 4G (I9305) with the painful Outlook app installed. When my device has been restarted (or it's accidentally gone into safe mode after a restart and I've had to come out of safe mode and back into 'normal' mode again) my Outlook app has wiped/lost all of my emails/contacts/calendar details and I have to re-sync everything again - which takes ages and saps up a load of my data allowance. This has happened maybe 6 times now, 2 of them being in the last week. It doesn't happen every time I restart the phone, just every now and again but surely the app shouldn't be losing all of this information causing me to re-sync. I don't understand why it just 'disappears'. Has anybody else faced similar issues? It's a puzzling and highly annoying predicament!

Thanks in advance for any help you guys can offer!
