Hi @Tarek Hassan

Welcome to the community!

Based on the error provided, Jira cannot connect to the Microsoft Outlook Exchange Server/Service. Your company network is likely restricted to the outbound/inbound network connection, which requires your network team to whitelist it.

Thank you.

Thanks Victor,

I discussed with the network team and Jira server has an open connection with O365.

also, I tested all possible connections and all were successful.

Are there a particular test to check (as I can send emails from Jira and receive them "Outgoing mail >> The connection was successful."

Any help will be much appreciated!

Best Regards,

Tarek

Hi @Tarek Hassan

Outgoing (SMTP) and incoming mail servers are using different ports.

Since you are trying to configure an incoming mail server with IMAP, please verify with your network team if the following ports are whitelisted:

• IMAP: 143
• SECURE_IMAP: 993

Thank you.
