Hello everyone,
I have a problem with Exchange 2013: After a few hours it stops receiving external Mails. Die service does not stop or change in any way. It is still running but I do not receive any Mails from outside the domain. But when I do a restart it is working again for some time. But I have to restart it over and over again. This is really strange.
Is there anything I can do?
Thanks!
Regards
Christian
