OS X 10.10.0 black dot on sent folder in mail

I had the same problem but after doing some investigation this is what I believe happened:

Looks like for some reason the black dot is because you don't have a "SENT" folder define. This is what I did to fix it.

I found a "SENT" folder under my INBOX for the same account. This SENT folder is the same that I have in my mail server, when I was sending mails from my mail server the mails showed up on this SENT folder. When I was sending mails from my mac mail I was loosing them (same as happened to you).

So I choose (highlight) this folder, then I went to menu bar-> mail folder -> use this mail folder as -> Sent Folder. (the name might be a little different since I don't have an english version of the mail).

After choosing this option the black dot disappear and the sent mails start showing up again.

Hope this helps.

I got the same problem here, but I can't even chose a "use this as" option, it's not selectable.

Luciusfrombasel, you might need to select the "SENT" folder or the "SENT MESSAGE" folder just like George, and once you have it selected then go to Mailbox in the Menu Bar > Use This Mailbox As -> and selected Sent Mailbox.

Thanks for your answers, I found a solution too:

I made a new mail account (same mail-adress) which is working quite fine without black dots and deleted the old one..

THANK YOU so much! This fixed my problems with the Sent folder and the Draft folder as well. Much appreciated!

Thank you for that. this resolved issue promptly

Does anyone know if these emails were actually being sent? before the problem was fixed?

Hi Axlemax,

yup, I'm sure the emails were getting to their recipients. I sent quite a few panicky duplicates to a client one night thinking they were getting lost, but it turned out she received them all.

Removing the "Black Spot" was the key. i.e. selecting a sent folder (not the one with the Black Spot) where you would like the sent messages to go, highlighting it, going to Mailbox (in the Menu bar) dropdown, "Use This Mailbox As", Sent.

Couldn't be easier. Other than the fact it took 4hrs for me to find this solution on the boards!

Hey-Ho.

Brilliant!

Simple solution to hours of frustration.

I've neve felt more alive!

This helped me. A new sent folder was located under the Inbox account, but I had an older sent folder below under Sent mail. I selected the new sent folder and chose Mailbox>Use this mailbox as>Sent mailbox but it was grey. Then I selected the old sent folder below and chose Mailbox>Use this mailbox as>Sent mailbox and it worked! The sent folder above disappeared and the black dot on the older sent folder now had the airplane icon. It did not retrieve prior messages sent, but everything new being sent now appears.

This response is the one that solved my problem. When I selected the entry that I believe George was referring to – the one with the black dot next to it – the "Use this mail folder as" options were greyed out. But when I found the folder in my Inbox containing the "Sent" folder, as Coctavio_sanabria suggested, I followed the same instructions that both responders were basically saying and this did work. The only confusion I had was where that folder was located. Thanks to both of you.
