Gmail domain chat messages sent offline now arrive as emails instead of chat messages

Question

gmail

Friends, tell me please.
I use Google Apps for the domain. In particular, I actively use chat (jabber). Recently, messages sent to me when I was not online stopped coming to the jabber client. Instead, they come as letters. It is very uncomfortable. I feel like it has something to do with the recent release of Hangouts. In the settings of Google Apps, I covered everything that is possible. Found the only option:

Enable the new version of Hangouts for messaging and video calls
The new version of Hangouts adds Google Talk functionality to video calls
. If you use Google+ Hangouts for video calls, you can skip this announcement.

- Enable the new version of Hangouts for users in this organizational unit
- Do not enable the new version of Hangouts and keep the current settings

It was included. Turned off, but the result did not change.

Answer 1

It has always been like this if, after offline, you first open the mail web interface, and then the Jabber.

Answer 2

This is not related to hangouts. There is some kind of dependence, I used to always get everything in the jabber client, then it began to fall like in your mail. But that changed a couple of years ago for me, not now. Like letters, they always lie in gmail, only some fly to the jabber client, and some remain letters.
