Case creation from inbound email not working

I’m running SuiteCRM 8.8.0 and got the issue that cases are not being created from incoming e-mails.

  • The inbox is configured properly, I can see the mails in the “E-Mail” module.
  • For the inbound mail account I enabled “Create Case from E-Mail”.
  • Under “Case Module Settings” I have “Enable Case Automations” enabled with “Round Robin” distribution method and “ALL” users as a target.
  • I can see the “Process Workflow Tasks” and “Check Inbound Mailboxes” scheduled jobs being executed successfully.

In the logs, I observe the following errors:

[FATAL] An Imap error detected: "IMAP close error"
[FATAL] ImapHandler trying to use a non valid resource stream.

My inbox is hosted by a Microsoft Exchange 2019.

Any ideas?

Hello,

the cases seem to be working just fine:

Try to look at the IMAP issue first like rsp suggested.
Did you find a solution into this direction already?
