Background:

Directory sync is located in the internal network and is behind a TMG proxy. TMG Proxy has been configured to allow Directory Sync to access HTTPS of the internet.

Problem:

With Directory Sync installed, the synchronization fails from time to time after a few hours of sync (we have >10,000 objects to be synced to the cloud).

Root Cause:

Directory sync should have direct connection to the internet. It is known to create issues if it is behind a TMG Proxy.

When setting up Office365/Exchange 2010, it is very common to assist the customer to create distribution groups.

This is my way to script it to speed up the creation of the distribution groups:.

1. Create a CSV file for each distribution group. For my case, I have _AllStaff.CSV created. See below link for the sample of the file.

_AllStaff

2. Use Powershell and run the following:

$name=”AllStaff”

(The above should be the filename of your CSV file).

New-DistributionGroup -Name “_All Staff” -alias $name -primarysmtpaddress $name@abc.com -memberdepartrestriction closed

(Modify the bold items to the right Distribution Group name and domain name)

Import-csv “D:\$name.csv” | foreach {add-distributiongroupmember -identity $name@abc.com -member $_.EmailAddress}

(Point the location to the CSV file, and also specify the correct distribution group name)

What’s your way in creating the distribution group?
