There is a limit of the number of addresses Outlook will allow in the TO:
field. The limit is based on size of data (such as 32,000 bytes), not
number of email addresses.

I would use blocks of 100 contacts or so and email 3 emails.

I have around 300 contacts in my contacts folder. However, when I create a
new email and click "To" or "Bcc" to add ALL of my contacts, only about
half
or so show up! Why can't I choose to email the other contacts?
