When you have multiple accounts in your profile Outlook sometimes has a problem recognizing who "you" are and includes all email addresses in a Reply to All. Beginning with Outlook 2003, Outlook handles it better and as long as the address the message was sent to is the same one you are replying From for the account, it will be removed when you choose Reply to All.

To automatically remove your address when replying to all, use one of the Tools listed below. You can also use VBA. See E-Mail: Remove recipients before sending for a code sample by Outlook Developer MVP Michael Bauer.

Reply to All includes myself

I'm seeing too many Outlook users complain that 'reply to all' includes their own address. While this was a common problem years ago, Outlook now does a good job identifying "who you are". It should only include yourself in the reply to all if the address the message was sent to is not the same as the account address.

If your From address is the same as the address the message was sent to, Outlook can properly identify your address and will not include it in a 'reply to all'.

When Outlook is confused, the possible causes include:

1. The Reply to address in File > Account Settings > More Settings is not the same as your account email address. When people reply to your address, Outlook sees that address as belonging to someone else.
2. Outlook is using the x500 address, not the SMTP address (Exchange mailboxes only)
3. You have one or more contacts in Outlook for your own GAL entry and one contains the wrong address. Outlook is resolving to the copy in your Contacts, not the GAL. (Exchange mailboxes only)

In each of these situations, the From address is different than the account address so Outlook included it in the Reply to all. Case solved.

Note on item 3: While it seems odd that Outlook is resolving reply addresses to contacts when it has the address already, it's my experience that Outlook resolves to display names, even when it has an email address to compare. I recently attempted to create a Contact Group using a list of first names and contacts (in firstname alias@domain.com format, one person per row). When I pasted the list into the Members field, Outlook 2013 consistently resolved contacts to other people with the same first name. I had to use email addresses only to insure the Contact Group was correct.

Always Include Yourself in Replies

If you are used to this 'feature' from older versions of Outlook and want to include yourself in replies sent using Outlook 2003 and up, you'll need to create an after sending rule to CC yourself. If you want to BCC yourself, you'll need to use VBA or an add-in listed at Automatically BCC all Messages.

To create a rule in Outlook 2010 and newer:

1. Open Manage Rules and Alerts (Home ribbon, Rules command)
2. Click New Rules
3. Select Apply rule on messages I send
4. Select conditions if you only want to be CC'd on certain messages or click Next to CC yourself on every message you send.
5. Under Actions, locate the CC action and enter your email address.

You can also open the Rules and Alerts dialog by right-clicking in the message list and choose Rules > Manage Rules and Alerts.

To create a rule in Outlook 2007 and older:

1. From the Tools menu choose Rules and Alerts
2. Select Create from a blank rule and choose Check after sending.
3. Select conditions if you only want to be CC'd on certain messages or click Next to CC yourself on every message you send.
4. Under Actions, locate the CC action and enter your email address.
