As advised by one of your team moderator in a private message, I post this message in order to obtain personal help about my problem : 

 - I configure hotmail into an IMAP account.

 - After a couple of days with bugs, the bug was fixed during a few days, but, since 2 days, the synchronization of my inbox doesn't work, while other folders continue to work correctly, not all the time, but most of the time.

Please, could you help me to fix the bug?

Thanks a lot!
