main identity problems in an iMac

After I had erased the hard drive i used my Time Machine to restore everything. When I tried to open Outlook and used the same Mail Identity as before I received a message that index is missing for my Office databas and must recreate it. Then I imported my latest backup for Outlook an olm file and tried that new main identity. All my old e-mails was there but not my contacts and calendar, they were in princip empty. In my TM I can see my earlier main identity and I have found all my contacts (olk files). The problem is that I don´t know howe to import those files från TM to the second main identity (from olm). I haven´t found where my calendar is in the TM. Is there someone who can help me how to proceed?
