Dear mates,
In our process log, a synchronization error appear several times per days.

Here's the detail of one error:

And the message error detail:
Terrasoft.Mail.ImapException: Impossible de se connecter au serveur mail . Vérifier les paramètres de connexion ---> MailBee.MailBeeSocketTimeoutException: Socket connection has timed out. InnerException message follows: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond XXX.YY.ZZ.TTT:993 ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond XXX.YY.ZZ.TTT:993
Impossible de se connecter au serveur mail . Vérifier les paramètres de connexion
=> Impossible to connect to the mail server. Check the connexion param
However the mails are working fine on computers. We can send and receive email even automatically.
Do you have and idea of where the problem can come ?
Thank you,
Regards,
Nicolas
