When I click "reply-to-all" in Outlook, my address is automatically put in the TO line. Since I usually don't modify the TO line when I reply to all, I just end up receiving any mail that I send.
It was not always this way. What can I do to fix this?
Deleted oab files solved problem.
Edit
An offline address book (OAB) is a copy of a collection of address lists that has been downloaded so that a Microsoft Outlook user can access the information it contains while disconnected from the server.
Offline Address Book (OAB) files, by default, are located in subfolders in the following Outlook folders:
In Windows 7 or Windows Vista:
\Users\<username>\AppData\Local\Microsoft\Outlook\Offline Address BooksIn Windows XP:
\Documents and Settings\<username>\Local Settings\Application Data\Microsoft\Outlook\Offline Address Books

I found another cause for this problem: entering an incorrect e-mail address in the Account Settings dialog:
Note the missing h in the first fredsmith. The address entered in that field isn't used to identify you to the mail server, but it is used as the From address on your outgoing mails. When replying to a received mail, Outlook will add you to the To field if this address doesn't match an address the original mail was sent (or cc'd) to.
If that address is correct, click More Settings... and check the Reply To address. Exactly the same applies there.
I personalized the users copy of the outlook client by entering their name in 'personalize your copy of microsoft office' in outlook options > general > 'personalize your copy of microsoft office'
This simple fix resolved the issue for this strange problem for us. The issue was within outlook 2016
