Hello,

I'm trying to find out what the limit is of creating distribution list in Exchange 2010.

The answers I find is the maximum of recipients within a distribution list. 

I think we would like to create more than 3000 distribution lists. Is that possible? What are the limits?

I dont think we have a limit for the no.of distribution groups. 

Hi ,

Agree with Johnpaul .

Based on my knowledge those objects count depends upon active directory and not in exchange.

Maximum Number of Objects

Hi Silvanoo,

Thank you for your question.

Microsoft didnt clarify the limit of distribution group, but more than 3000 distribution group is no problem, you could do it.

If there are any questions regarding this issue, please be free to let me know.

Best Regard,

Jim
