Im trying to start the IMAP4 service, but it stops immediately after being started. When trying to start the service from server manager I get the error message, "The Microsoft Exchange IMAP4 service on SERVERNAME started and then stopped. Some services stop automatically if they are not in use by other services or programs" The event log records three errors: 1. Failed to start listening (Error: 10048). Binding: :::993. 2. The address is already in use. Binding: :::993. 3. Failed to open one or more bindings. The service will be stopped. What am I doing wrong? It seems like possibly some process is already bound to port 993...? I'm not sure how to go about checking that specifically. Thanks.

One more thing, I tried "telnet 127.0.0.1 993" connection failed...

It's possible a process is already listening to 993, you can use netstat -an to check that from a command prompt. Pipe the output to a text file and do a Ctrl+F for 993. If the error actually has those three colons rather than IPs then I'd suspect the bindings for the IMAP service are messed up. You can configure these in the Server Configuration\Client Access section of the EMC.Active Directory, 4th Edition - www.briandesmond.com/ad4/

Ok, you might be on to something. EMC\Server Config\Client Access... on the Binding tab for IMAP4, in the Secure Sockets Layer Connects section, there are two items listed: (All available IPv6 addresses) : 993 (All available IPv4 addresses) : 993 When I try to edit IPv6, the window that comes up asks me to specify an IP and it has :: in the field. If I change the option to Use all IP addresses available on this server, I get an error that the value 0.0.0.0:993 is already present in the collection. Conversely when I try to edit IPv4, the radio box selection for Use all IP addresses available on this server is already selected... Should I delete the IPv6 item from the list?

You can't select the "use all IP addrersses . . ." radio button for the IPv6 address range. Instead, specify a specific address. If you want to listen on all available IP addresses: .. The IPv6 binding should be: .. 0000:0000:0000:0000:0000:0000:0.0.0.0:993 .. If you select the "Use all available . . ." for IPv4, the IPv4 binding will be: .. 0.0.0.0:993 You can see the bindings easily enough like this: get-imapsettings | fl *bindings UnencryptedOrTLSBindings : {0000:0000:0000:0000:0000:0000:0.0.0.0:143, 0.0.0.0:143} SSLBindings : {0000:0000:0000:0000:0000:0000:0.0.0.0:993, 0.0.0.0:993} --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

Well I installed a couple of exchange rollup updates, restarted the server and magically the service started working.

May I know which Rollup Updates to install to fix this problem please ?
