After a request to rebuild the main identity all my emails accounts disappeared

Hi there,

I had few messages errors while trying to open my outlook asking me to rebuild the main identity. After doing it 3 times, and cancelling at the 4th I lost all my data in outlook. its totally empty.

I have access to the files Main Identity backed-up from today and I am trying now to rebuild it but its taking a long time and I a not sure it will work as it is the reason why my outlook has been giving me hard time to use.

Any advice?
