Hello, I need to set AcceptMessagesOnlyFrom for a user. I got an error message on the ECM. (A value in the request is invalid) Any possibility to set it up from the shell console?

Hi, The group which you are trying to add have to mail enabled , otherwise, you wont be able to add the group. It is possible using both EMC/EMS. Please refer below for the cmdlet to achieve this. http://technet.microsoft.com/en-us/library/bb397214%28EXCHG.80%29.aspx thanks ThiyaguThiyagu | MCTS/MCITP - Exchange 2007 | MCSE 2003[Messaging] | http://www.myExchangeWorld.com.

Hi Graiggoriz, Any updates on your issue? Please also provide more information. Do you want to Set-DistributionGroup or Set-Mailbox? And please post the full error message here.Frank Wang
