So I opened my big mouth and got myself a (voluntary) job.
I find myself with a database of around 300 members, 40 of whom have email addresses and none of whom have complete data. I therefore need to contact all of them.
Whilst sending a letter to those without email addresses is easy, sending emails to the rest is proving problematic. I keep being told there is no default email address and that I need to download Microsoft Office Outlook. Apart from the cost, I don't want to use Outlook, I need to use web-mail as other committee members will need access from time to time.
The IMAP was just an idea so that others might be able to view the same folders.
Back to your basic question, doesn't look as if mailmerge will be easy or possible Using MS Word 2007 & WLM 2011 for Mail Merging click here however it does say you can send individual emails (with attachments) from Word using WLM.
A word of caution, if other committee members are going to be accessing the email occasionally then I would definitely create a separate email address and account for the organisation, you don't want to be giving out your email address and password.
You can do Gmail and mailmerge with Google docs AFAIK
