@Komal-Sharma
thank you very much for your feedback.
We use an IMAP connection (Zimbra server).
Here are the requested captures:

Hello,
We are deploying the Uvdesk solution for the first time.
We're having a problem retrieving emails.

The error message is as follows:

We don't see any errors in the logs, only warnings.

The UVDESK version is "uvdesk-community-v1.1.3".
The PHP version is 8.0

Can you help us?
