Sorry, more details...should have said first!
Windows 10, MS Edge BT Yahoo Mail....my home page is https://www.bt.com/.
Click on Edge....home page opens.
Click on BT home page 'Email'.
Sign in boxes appear on right.
Click on 'BT ID or Email address'
My Email addresses appear (I have half a dozen that I use) I then click the one I want.
Hope that is OK....Thank you😀
Hi @EJB thanks for posting that information which clarifies your question. The information stored is done by your internet browser and not the BT website.
I am not sure it is possible to just delete selected addresses from the list. I think you may have to clear them all via your browser settings and start again using only the ones you want.
