This powershell is passed in exchange 2010!

Param
(
$ Temppath = "C: \ log"

# Define the log output path
)

If (! (Test-path $ temppath ))

# Determine whether the Log Path exists. If not, create a directory.
{
New-item-path $ temppath

# Creating a Log Path
}

$ Groupnum = Get-distributiongroup

# Output all distribution groups to a variable

Set-location $ temppath

# Change Command Execution path
Foreach ($ groupnow in $ groupnum)

# Cyclic Distribution Group
{
$ Groupmember = Get-distributiongroupmember-identity $ groupnow. Name | select name

# Output contact group members and only output names
$ Tmppath = $ temppath + "\" + $ groupnow + ". CSV"

# Define the file exported by the output contact group members
$ Groupmember | export-CSV-path $ tmppath
# Export the contact group members as CSV files

}
