can you exapain a little more what you have tried to do and where you failed?
I would start somehow like this:
- Pick the appropriate Quota rule set from the library
- import it three times, make sure you create a new setting for the quota setting for each of those
- configure the allowed timespan for the three time quota settings
- set a criteria within the rule set to only match the group you wish to match for the specific quota setting
Where exactly where you experiencing problems?
