Hi,
I’m sending an email via SMTP, if I try to send authenticated until the UiPath.Mail.Activities v1.9.5 version works, but if the version is higher than the UiPath.Mail.Activities v1.9.5 it gives an error, as shown below:
ERROR:
SUCESS
ERROR TESTED VERSION UiPath.Mail.Activities: 1.9.6; 1.10.4; 1.10.5
Even I am also facing this same issue. I have to use the v1.9.5 for the sending the mails.
@kumar.varun2 can you please send me the error message you get?
@kumar.varun2 @joao_adelio1 can you please give me the value you are using for parameters? For me it works fine in 1.10.5 when using Server = “smtp.office365.com”, and Port = 587, SecureConnection = Auto.

Also, in v1.9.5, while using the secure string as password the same exception is thrown so I have to use the plain string as password
Server = “smtp-exchange.sicredi.net”
Port = 25
while using the secure string as password the same exception is thrown so I have to use the plain string as password
try this, in the normal string field:
New System.Net.NetworkCredential(String.Empty, SECURE STRING).Password.ToString()
replace secure string with your secure string coming from the orchestrator for example, that was the way I found not to expose my password in the code
You need to use 1.9.6 or newer to get the activity working correctly when setting a value for SecurePassword parameter. If you have to use 1.9.5 then you should use Password field instead.
Looks like it worked but the username/password is wrong.
It’s not incorrect brother, if I put the method in the normal string:
New System.Net.NetworkCredential(String.Empty, password).Password.ToString()
which simply converts the secure string into a normal string, works correctly, believe me I’ve done all possible tests 
Sounds like your mail server doesn’t support secure authentication and so it sees the secure pwd as an incorrect pwd rather than decrypting it. Also could be a certificate issue.
I tested with versions 1.9.6, 1.10.4, 1.10.5 and 1.11.0-preview with both Password = “{my-password}” and SecurePassword = new System.Net.NetworkCredential(“”, “{my-password}”).SecurePassword. I used Server = “smtp.office365.com", Port = 587, SecureConnection = Auto.
==> All runs were successful, i.e. the email was successfully sent and received.
Note: the first execution failed with an authentication error but the reason was that I haven’t used my outlook.com account for a while so Microsoft blocked the access to my Inbox. But after I reviewed my activity and confirmed it was me initiating the call, everything worked fine.
Hi,
I’m facing exactly the same issue.
With exactly same set-up(same VM, username, password, server, port) -
Send SMTP Mail Message activity works well up to package version 1.9.5.
since version 1.9.6 and higher (1.10.4,1.10.5) I’m getting error message:
MailKit.Security.AuthenticationException: 535: 5.7.3 Authentication unsuccessful
** at UiPath.Mail.Activities.SendMailActivity.EndExecute**
Tested with various accounts, passwords as a plaint text or secure string - no help.
Seems to me like a bug in the newer versions of the UiPath.Mail.Activities package.

Hi,
I am facing exactly the same issue…
If you had a feedback and a workaround…
Thanks,

Didn’t find any solution to this. I am using the 1.9.5 version of mail package to avoid this problem.
Can you please try with the attached mail package?
With the following attributes
UiPath Studio Version : 21.10.3
Mail Package Version : 1.12.2, 1.13.0-aplpha.2080912
port : 25
Secure Connection : None
It is working with both the versions of package.
