Hi, I really hope someone can help me. I have been searching for solutions on this and other forums and haven't found a solution that has worked for me yet. Yesterday my Outlook froze when I was trying to open a new message. I eventually had to force quit it. When I restarted Outlook there were no emails, no folders, nothing at all. From searching around I realise that this is a problem that others have had, so I have tried various things in vain. I have a time machine, which is backing up regularly. I did a full system restore to 1 hour before the problem occured (which took 3 hours) but Outlook was still the same. I have looked back at time machine versions but oddly there is no 'Microsoft User Data' folder at all in My Documents before 24 hours ago. It just disappears in earlier versions. I have started the microsoft database utility programme and that only finds the current (blank) identity. It repairs it in all of 15 seconds but that is because it is blank. No other identities are showing. I have searched for other identities or copies of 'main identity' in other folders. There are none in the last year. Older versions are previous backups I made before I got the time machine. when I search for specific email in finder they are showing as being in the system. so the emails are all still there. But when I try to open them in Outlook it says that the message is not associated with that identity. Where can my identity have gone? And how can I get it back? Is it worth trying a full system restore on time machine for 4 days ago? Will it find the database that appears to be missing when you search for folders on the time machine? Any help/solutions would be much appreciated. Thanks in advance.
