[Evolution] Failed to issue notify - error

[Lucas Merckelbach <lucas merckelbach hereon de>]

Dear all,

I have been using evolution on mostly Fedora in the 
research institute I work for about 11 years now. Today the institute has 
officially changed its name, as well as email servers and all that kind of 
thing. Also today evolution stopped working properly. When I log in I get 
this error message:

Failed to connect account “lucas merckelbach hereon de”.

The reported error was “Failed to issue NOTIFY: NOTIFY not supported for 
these mailboxes (0.001 + 0.000 secs).”.

I am convinced that IT messed things up, but, because they support 
windows only, they don't give my problem a second's thought. I have no 
clue what is the issue here, and an extensive search on the web has 
returned nothing. Would someone be able to explain what this message 
means, and what might have caused it?

My version of evolution is 3.38.4 (3.38.4-1.fc33)

Many thanks in advance,

Lucas
