Hello

I have some difficulties to add my 8 mail accounts on my new iPad. The accounts are working on my old iPad.
When I add an Exchange account, the verificaion doesn't succeed. If I add the account anyway, the iPad says : "account errors, connection to server failed" and the mails are loaded very slowly. Sometimes, very rare, the account is accepted.
I have tested with wifi and 4G
I don't understand, none of the IPs in he logs are mine.


Sorry for my english, I'm french.
Thanks for you help, here's the logs :

Update /etc/default/sogo, increase the prefork child processes, restart sogo service. That's it.
