the transaction was not transmitted because of the dust exits [urgent]

[CryptD38]

Hello

After more than 10 days of learning, I am trying to make my first outing with electrum (latest version 3.3.8 )
He asks me to change the server. What I did 4 or 5 times.
I still have this message "the transaction was not transmitted because of the dust exits" !!
As the course is moving a lot, I would like to do it this evening * so as not to be short of mBTC
Thank you for your help

Exactly the same question was answered today in this topic. TL;DR one of your outputs is equal to or lower than 546 satoshis (0.00546 mBTC) or 296 satoshis (0.00296 mBTC) if you are using a SegWit address. You can find a more detailed explanation in that topic.

Hello
Thanks but I'm not sure I understood correctly because the exchanges are long and I don't speak English well
I did a test on testnet but maybe the amounts of the last 3 outputs are too small?
It was to anonymize a little by sending me mBTC to several addresses to send it later to a provider
See https://framapic.org/2IxosAn2PGxJ/zBleyfkbU712.png
Is there a minimum for the 3 outputs?

Is there a minimum for the 3 outputs?

Yes. Three of your outputs are 0.001 mBTC, which is equivalent to 100 satoshi. As BitCryptex has said above, the minimum output you can send is 0.00546 mBTC, or 546 satoshi. You either need to remove those 3 dust outputs from your transaction, leaving only the one for 6.21 mBTC, or you need to increase the amount in each output to above the minimum of 0.00546 mBTC.

Sending the minimum amount to 3 different addresses will only cause you more problems further down the line when you try to send them on, as once you deduct the fee from the minimum amount you will again have too small an output to send. Sending to an intermediary address before the final destination also does next to nothing to anonymize your transactions. If you are trying to anonymize your coins, you would be far better off looking in to a mixer such as ChipMixer, or a CoinJoin transaction.

very clear
Thank you

usually this means that you're confusing mbtc with btc. you should change the default unit to btc under tools > preferences > general tab > base unit option. then attempt to send coins again this time keeping in mind that you are dealing with btc and not mbtc.
