Outlook 365. Win 10 pro.
Delay in the delivery of letters.
Mail server nic.ru
The IMAP protocol is used.
Letters come to the device with Android immediately. 1-3 minutes. To Outlook 365 (Win 10) - in 1-5 hours.
Is there a solution to this problem or not?
All I found is that it can be due to the creation of folders and working filters. The decision to remove filters and folders is not an option.
Why is this Outlook needed then?
