8. After the install is finished open BlackBerry Manager, an error will appear about MAPI client which you can just hit OK. The MAPI setting windows will appear so just add the server name back in and select "Check Name", if it resolves just hit OK and the manager will start.
I have pure exchange2007 environment. I followed every instruction but when starting BES manager i always get error about MAPI no matter what i try.
Nobody seems to have any solution to this problem.
