1) New install sles 11 + oes 11
2) Have backup of domain and postoffice from a dead Groupwise 8 server
3) Upgraded to Groupwise 2014 using copies of the Backup of domain and post office copied onto new server.
4) Everything works - except:

One account on the groupwise 8 server had corrupted database entries. Upgrading from backup sorted out the emails

but now the main calendar is missing

No calendar tab in the Nav Bar
No calendar entry listed below "home"

Is there anyway or getting a calendar or will I have to delete that account and create it again?

Many thanks in advance for any ideas
