1) what effects will deleting my .ost have?
- reason: because of the sync issues, contacts on both my .ost (laptop) nor my phone (windows based smartphone) have synced correctly – any changes made in those two areas are NOT reflected on my OWA contacts profile. again, restating perhaps – I’m not worried about the calendar (as it’s not syncing either) because I’ve pretty much had to stop using it due to the errors. any ‘new’ changes I’ve made to it have been made solely on webmail (thus I haven’t used it much as I dno’t like the interface!).

2) what effects have you seen in not running in cache mode?
- reason: wouldn’t this mean that I no longer have access to much information (see contact data etc. when I’m not connected/ offline). I’m mobile quite a bit, and tehre are times when I can’t find a good / any access to the internet – are all of my folders then unaccessable?

3) I’m sure I have some more…but any basic understanding you could provide would be greatly appreciated. I certainly want to retain the contacts that I’ve made/ created/ updated on my laptop that aren’t reflected in the current OWA profiles.

Thank you again!
