Hello,
iRedmail was installed without any problems and it works perfectly. I also use SOGo as a web interface.

Our problem is that, our emails can arrive quickly to the sogo interface, in about 1 minute. However, it arrives in Microsoft Outlook 2024 after about 20 minutes. I reduced the synchronization time from Outlook to 1 minute. I also reduced the refresh time from the SOGo web interface to 1 minute. Despite this, the emails arrive after about 20-25 minutes.
How can we solve this?

Thanks in advance.
