Our clients here use POP3 and IMAP to connect their MACs to the server.
Stangely every 2nd day in the past week or 2, the IMAP 4 and POP3 service had to be restarted to get things going again.
Note, the services never shutdown but still had to be restarted.
Upon restart, the following errors came up in event logs.
Can anyone recommend what we need to do??
Secondly SBS 2011 server that we have EXCHANGE 2010 SP1 (Rollup 6) installed.
I am aware that Microsoft doesn't release Exchange SP updates for SBS 2011, but should I manually install SP2 and SP3??
Errors (same for both Pop3 and IMAP) -
Eventid2011 - ServicePrincipalName.RegisterServiceClass returned error code 2146.
EventID1004 - Basic authentication is available over plain text connections.
