    Hi,

    I am working on a Powershell script to restrict sending messages to certain distributiongroups. I'm reading the information from a CSV file and

    the cmdlet is set-distributiongroup -identity $CSV.Group -AcceptMessagesOnlyFromSendersOrMembers $CSV.Accepts

    the problem is that AcceptMessagesOnlyFromSendersOrMembers is a multivalued property. How can I put the separate smtp addresses into a variable, which is understood by the above cmdlet? Any samples?

     

     

    regards, Richard Neuteboom

    Hi Richard,

    I would suggest you seek the solution in the Development Forum:

    http://social.technet.microsoft.com/Forums/en-US/exchangesvrdevelopment/threads

    Just for reference: It is easier if you can create a temp DG to include the mail addresses. The following cmdlets are to add all members of the tempDG to "Only senders in the following list" of restricted DG.

    $DG = Get-DistributionGroup "restricted DG"

    Get-DistributionGroupMember "tempDG" | foreach {$DG.acceptmessagesonlyfrom += $_.DistinguishedName}

    Set-DistributionGroup "restricted DG" -AcceptMessagesOnlyFrom $DG.acceptmessagesonlyfrom

    Please use AcceptMessagesOnlyFrom instead of AcceptMessagesOnlyFromSendersOrMembers.

    you can update multivalue property like this:

    Set-DistributionGroup "Group1" -AcceptMessagesOnlyFromSendersOrMembers user1@domain.com,user2@domain.com

    -join("74686979616775313440686F746D61696C2E636F6D"-split"(?<=\G.{2})",21|%{[char][int]"0x$_"}) www.myExchangeWorld.com This posting is provided "AS IS" with no warranties, and confers no rights.

    it looks like this:

    Group;Accepts
    samplegroup;user1@mydomain.com,user2@mydomain.com,user3@mydomain.com

    Hi Frank,

    Thanks for your help. I have got the script working for a single group and reading the members from a csv file. the next time I will search the Developement forum. I need to enhance the script so that it can read the groups and members from a CSV file, because I need to migrate about 1400 distribution groups from a Unix Listserver.
