Solution 1Recommended

Disable Email Forwarding in Outlook.com

Ask your colleague to check their Outlook web settings and disable any active forwarding rules directing mail to you.

In most cases, this issue occurs because a colleague has enabled a forwarding setting on their account. They will need to log into their own Outlook account to remove the rule.

1
Open Outlook Settings

Have your colleague log in to Outlook.com, click the gear icon at the top right corner, and select 'View all Outlook settings'.

2
Navigate to Forwarding

In the settings menu, click on 'Mail' in the left pane, and then select 'Forwarding'.

3
Disable the rule

Uncheck or toggle off the 'Enable forwarding' option.

4
Save changes

Click 'Save' at the bottom to apply the changes and stop emails from being redirected to your inbox.

Disable Email Forwarding in Outlook.com
Check Specific Inbox Rules: If general forwarding is not enabled, the colleague should also check 'Mail' > 'Rules' for any specific conditional inbox rules that might be forwarding messages to your address.

Frequently Asked Questions

Can a colleague forward emails to me without my permission?

Yes, anyone can set up an email forwarding rule in their own Outlook account to send their incoming messages to your email address. You will need to ask them to disable it from their end if it was done in error.

Will disabling forwarding delete the emails I already received?

No, disabling the forwarding rule only stops future emails from being sent to you. Any emails that have already been forwarded will remain in your inbox until you manually delete them.

Are forwarded emails marked differently in Outlook?

Typically, a manually forwarded email will show 'FW:' in the subject line. However, if an automatic inbox rule is used to redirect messages, it might appear exactly as it did to the original recipient without the 'FW:' tag.

What if my colleague cannot remove the forwarding rule?

If your colleague is unable to remove the rule, you can create an inbox rule in your own Outlook account to automatically delete or move any emails originally sent to your colleague's address into a separate folder.
