Hi All

I am in a position of doing cross forest migration. Source Exchange is 2007 and target 2013.In the source mail box has got recipient limit set(ex 50). currently we are in a co-existence scenario. when a migrate user send a mail to many distribution list the user receives too many recipients error. which is generating by the remote exchange server(source). Is there away to overcome the issue without increasing the recipient limit on the source enabled user?

Hi Winnie,

i am currently in a coexistence scenario. what is the best way to achieve this?

1. increasing user rec1pient limit

2. increasing connector recipient limit?

3. server rec1pient limit?

Hi,

Generally, there are many recipient limits in the environment: Organizational recipient limit, Connector recipient limit, Server recipient limit, User recipient limit.

If a message must be sent to lots of recipients but you don't want to increase the recipient limits in the environment, we can consider creating a distribution list for this task. Because Exchange Server 2010 treats a distribution group as one recipient.

If it still doesn't work, please send the message twice for different recipients.

Hi, 

the only way is to increase the recipient limit on the source domain.
