The limit is only on the contacts in the group, not on the number of groups, and this only applies to Outlook groups, not distribution groups in AD, they have a limit of 5000 entries. The Limit number of recipients per message does not effect how many contacts can be in the group, but if you send a message to a group that contains more than that limit it will bounce back to the sender stating that the Max number of recipients has been exceeded.

Is the limitation only how many contacts? Also, does the "Limit number of recipients per message to" affect how many contacts you can have within a distribution group? >From Microsoft: " The maximum number of contacts is 165 within each distribution group. If you use the very basic information for contacts (for example, only the name and the e-mail address), your limit may be 125 to 130 contacts. On average, the number of contacts that you can add is limited between 50 and 70 contacts. There is not an exact number of contacts that you can add, the limit is based on the total size of the contacts.
