Imap not working on 2013 servers - BAD Command received in Invalid state

Good afternoon.

I am unable to configure my Exchange server 2016 mailboxes on mobile devices.
The error thrown by the Microsoft test such as telnet are the following.

1 OK CAPABILITY completed.
C: 2 LOGIN <user> <password>
S: 2 NO LOGIN failed.
C: 3 LIST "" *
S: 3 BAD Command received in Invalid state.

Exception: Microsoft.Exchange.Tools.ExRca.Tests.ImapPop.MailProtocolException: 3 BAD Command received in Invalid state.
at Microsoft.Exchange.Tools.ExRca.Tests.ImapPop.ImapProtocolTester.SendCommand (String command, String logString)
at Microsoft.Exchange.Tools.ExRca.Tests.ImapPop.ImapProtocolTester.CheckMailboxHealth ()
at Microsoft.Exchange.Tools.ExRca.Tests.ImapPop.BaseProtocolTest.PerformTestReally ()


-telnet:

type BAD Command Error. 12
* BYE Connection is closed. 13

I tried changing the authentication, but it didn't work:


Name ActiveSyncEnabled OWAEnabled PopEnabled ImapEnabled MapiEnabled
---- ----------------- ---------- ---------- --------- - -----------
test True True False True True


[PS] C: \ Windows \ system32> Get-ImapSettings | fl LoginType
LoginType: PlainTextLogin

Could anyone solve this problem?

From already thank you very much.

Regards.
