Give it some time. Depending on the user the sync process could take some time. My boss had over 500 active tasks to sync and took nearly an hour. I suspect the more the user has to sync the longer the process will take. On average activation could take 5 mins for a completely new account and up to 30 minutes to an hour for some. The hour is a rare occurance and i tend to think it has more to do with the signal level and bb unit itself.
