How do I reply to more than one email at a time?

[andy]

We get a lots of replies to advertisiements and once we have completed our
process I would like to write one email thanking people and send it to all
the emails approx 100 at the same time.

Do I have to create a distribution list or is there a simpler way. i tried
"select all" but there is no "reply to all" feature I can see.

Thanks

You'll need to collect the email addresses first and then do a mail merge.
If all messages are in the same folder you can do an Export to Excel and map
the fields you need (most likely "email address" and "Display name" of the
emails). You can then use the Excel sheet as the data source for your mail
merge.
