Problem: You receive the error "sharing quota has been exceeded" or a similar error
Reason: This happens on newly activated accounts to help prevent spam and abuse of google apps.
Solution: Wait approximately 30 minutes until that account has time to be completely activated and then try sharing again.
Problem: The user you are trying to share with does not show up when you begin typing their name.
Reason: The user you are trying to share with has not activated there account or activated it recently.
Solution: Wait at least 24 hours for that users information to get populated into the directory. You can also share with that person if you know their universal login by sharing with them @adams12.org For instance if their universal login is "hod0123456" then you would share with "email@example.com"
