I installed Unity 5 couple days ago and I had some issue when use permission wizard and some event errors after the installation.
I first installed the latest permission wizard according to installation guide and grant permission. Everything is fine except it can't grant permission to "Deleted Ojects right" for unitydirsvc account. So I used the version that comes with the installation DVD. Surpricely it worked. So I went ahead to finish the rest of the installation.
Now after the installation, I saw a lot of errors in the event viewer. Almost all of them are related to Exchange.
It is CiscoUnity_MALEx, event ID 30003. It said "An attempt to access the Primary Exchange Mailbox Store by CsBMsgConnector via MAPI has failed. The MAPI subsystem return the following error: Your profile is not configured.. "
BTW, now when I re-run the permission wizard, I still got the same error. But if I used permission wizard report, it says all the permissions are granted. Strange, right??
