Is it true that Microsoft doesn’t allow more than 16 characters in their Hotmail password?

I’m trying to change my Hotmail password after a breach in LastPass but it doesn’t seem to work. So I’m curious if Microsoft has a limit of 16 characters for a password?

If so, this is very insecure and I’m getting this warning from LastPass:

Note that I am using LastPass to generate a secure password. It’s just if I make it longer than 16 symbols Hotmail doesn’t seem to accept it.

cannot send emails from hotmail server [duplicate]

This question already has an answer here:

  • Can't send outgoing messages in Mac Mail 8 answers

I am unable to send emails from my hotmail account set up on my Mac. I can receive emails but for outgoing it is giving me an error.

The sender address was rejected by the server

The server response was:

SMTP; Client was not authenticated to send anonymous mail during MAIL FROM [BMXPR01CA0008.INDPRD01.PROD.OUTLOOK.COM]

Select a different outgoing mail server from the list below or click Try Later to leave the message in your Outbox until it can be sent.

Suddenly today I have no hotmail and no emails! Where did all my emails go??

I have had my account for about 15 years and have my whole life on hotmail including airplane flights coming up, new classes etc. I need to have access to my emails and suddenly today I am not able to access my emails on my hotmail account on my laptop! I saw or heard no warnings of such a big change coming. How on earth did this happen this way?
