iPhone Sync - How to tell iTunes which Outlook Data File to use? (Personal or Exchange)
I have been using iTunes/iPhone sync for years without any difficulty. Calendars and contacts all going back and fore as expected.
Yesterday I added a new email account within Outlook - one for Office365, effectively a Microsoft Exchange account.
This seems to have done at least two things.
- It deleted all of my mail rules. This is documented online and I can deal with it.
- Created a new outlook data file (this time an .ost versus a .pst). It has made this file the "default".
So, now I have two outlook data files, one personal where I receive my POP mail and all my contacts and calendars are defined, and a new one, "ost" that is for my exchange email account.
The problem: when syncing, all my contacts and calendar entries have been removed from my iPhone. It seems that iTunes is syncing from my new exchange account (which has no contacts or calendar entries). I created one contact here and it went over to the phone.
Question: How can I tell iTunes that I want it to sync my Personal, old, Data File, not the new one?
I have tried to change the default data file back to my personal one, within outlook, but it says this:
The selected Outlook data file (.pst) format cannot be used. Outlook data files (.pst) must use the same format as the offline Outlook data files (.ost). Select a matching Outlook data file (.ost) or turn off cache mode in the Account Settings.
I do not really want to start messing around with Outlook settings, I simply want to tell iTunes _which_ Outlook data file to use for syncing.
Can anyone help me with this task?
Thanks and regards
David
