I would not recommend Outlook as a manager for a list that size, mainly because you can expect a 10% bounce rate for each mailing. Do you really want to sort through 5,000 returned messages manually? I would use a server-based (hosted or local) listserv for this, selecting one that can distinguish among different types of bounces and can handle provide a self-service unsubscribe feature. There are many such non-Outlook tools available. Use your favorite search engine to scout around.

I have a client that has over 50,000 contacts in Outlook organized in
different categories with the largest being around 27,000 contacts.
He uses these to send out company newsletters and such. I am trying
to find a solution for him to be able to use mail merge and send out
an email to these contacts and have yet to find a viable solution.
Everything we have tried usually ends up crashing or having an
overflow error due to the amount of contacts.

Does anyone know a way or an application that would work with this
amount of contacts? Price is not an issue.

We have tried eMailMerge4Outlook, PC iMail, and Go Mail. They didn't
seem to work but maybe we didn't do something right!

Thanks for your help!
