On RHEL 8 when trying to add an Exchange mail using the Online Accounts of the GNOME settings panel I encountered a problem which resulted in failure of the process. The log says that the goa_ews_client doing autodiscovery received a diffie-hellman prime sent by the server which is too small in size.
Searching for this issue I found that this was a problem identified a few years ago which was since fixed. Note that on Fedora 30 I do not have this problem.
Is there a temporary solution until this issue is properly resolved ?
