Failed to authenticate on SMTP server with username "[email protected]" using 2 possible authenticators

[despoberry]

Hello,

we have migrated a prestashop into Presta 1.7.6.0

now we have the problem that we cant send mails with our office365 account.

we are using the following settings:

SMTP-Server: smtp.office365.com
SMTP username: [email protected]
Encryption: TLS
Port: 587

Errormessage:

Failed to authenticate on SMTP server with username "[email protected]" using 2 possible authenticators

 

Do anyone have an idea how to solve this problem?

Thank you in advance.

Hello:

It seems something related to the smtp user or password. I create a new smtp user and password (without any extremly odd chars like '/' or '=') and that solve the same problem.

the password consists only letters (upper and lower), numbers and a dot.

yesterday evening two emails for a order were generated and sent.

if i try today any testmail the same error appears. its a bit strange

Hey folks! Thanks for this thread.  I was pretty lucky and got it on my first guess but in my case the problem was that I had an apostrophe in the password --> ' 

I guess (maybe) the backend code of prestashop does not accept this character?  Perhaps it refers to a 'string'.  It would be good to file this as a bug and make this character acceptable since I use automatic password creation tools like Keepass to create passwords and apostrophe is always there...

Hope this helps!
