I have a client who has built up contacts in his MS Outlook as and when they came for over a decade now. The thing is, due to a lack of vigilance when saving those contacts, there have been very many duplicates each holding different information about the same client while others holding the same information.
My question is, is there any software or any method by which these contacts can be cleansed, in that, the duplicates holding different information can be integrated into one, while the other duplicates can be deleted?
Secondly, how can I send one email to multiple contacts in Outlook.
PS: the Outlook version is 2010.
