Mail send button greyed out


I’ve an issue with the default email client. The account has been configured properly but I can’t send any email. The reason is simple: the send button is greyed out.

Any idea ?


I’ve the same isssue. I can only send mails to people who are in the address book. If I only enter an unknown recipient address, the button turns gray.

That isn’t true from my experience.

Yes, the button is grey after typing an email address.

Then click into the address field and select the address.

Button turns black and you can send your email.

Tested with mail app v1.3.2 some minutes ago.

Ok, i will confirm that. But something confuses people and produces unnecessary questions. The ease of use is modest. If I enter an address, I would like to be able to send immediately.

You are absolutly right.

Yep, this confuses colleagues every time.

Yes it’s almost ridiculous, and completely counterintuitive, Having to actually train even experienced users to do something like that where you don’t on any other web-based platform that I’ve encountered - the whole reason this thread is here.

I registered just so I could post here: I totally fell into this trap too. Thought I’d have to set up my own mail server or something before googling “nextcloud email button” :sweat_smile:
