Jira Service Desk IMAP connection to Exchange com.sun.mail.iap.ConnectionException

Hello,

I am trying to configure incoming email for JIra Service Desk, and I get the following error:

You need to check if you got the right port number for the IMAP(S) server that you are connecting to. That's what error 220 means.

[Adriana Stancu]

Thank you, the client said that the port was 587. I tried with 143 because I though that it is plain IMAP authentication but now I get Authenticate failed. There is the obvious reason that they gave me the wrong username or password, but could there be another issue with my configuration?
I have configured java system with

-Dmail.imap.auth.plain.disable=true

and

-Dmail.imaps.auth.plain.disable=true

[Timothy (Goldfinger Holdings)]

Hmm.. The port of 587 is normally associated with SMTP.

I guess you need to confirm if you want incoming or outgoing mail.

[Adriana Stancu]

They sure want to configure incoming mail. I have got the information regarding IMAP with 587, which seems odd, but I tried with 143 and I got the following error:

I have enabled telnet on the server and tried to connect to this mailbox using telnet. I am connected on 143 but when i run: 

? LOGIN [username] [password]

I receive either a syntax error, or a NO LOGIN message.

   

[Adriana Stancu]

They also want the outgoing mail configured, at the outgoing I get this error

[Timothy (Goldfinger Holdings)]

The error is pretty clear. You have wrong credentials. You should probably log into the account using a browser (e.g. from the server hosting the product) and the credentials to see if it working.

[Adriana Stancu]

I dont have access to open the mail using a browser. I tried over telnet but I was unsuccesful. I you can look at this error and confim that it is a problem with the credentials for sure?

I tried over telnet but I was unsuccesful

If telnet is unsuccessful, you probably have a firewall/port issue.

[Adriana Stancu]

It was a totally different password all along. Thank you very much for all the help!
