I've got some email addresses in *.xlsx file (about 300) and I want to import them into one distribution group in Microsoft Exchange.
The problem is some emails has already got a corresponding contact on my server (about a half of those emails) and other doesn't.
What's the easiest (or most elegant) way to add all those mails into distribution group? I don't want to check if 300 email addresses have their contact and then adding it all.
Have you tried exporting the existing group emails first into excel Export Distribution Group Members in Microsoft Exchange 2010 then using excel to look for emails in one list and not in the other?
