hi, i have a problem with a user connecting via imap. the error is: NO LOGIN failed."";RpcL=-1;LdapL=-1;Msg=UserConnectionLimitReached" i cannot seem to find much information about the "userconnectionlimit reached". if it is the same as the "maximum connections from a single user" option, it is currently set to 10. should these connections timeout as per auth/unauth connection timeouts? the user has waited to connect for several days and we still see the same error (client machine is just asking for password over and over) any ideas?

Hi, The error you provided seems like protocal log. Could you please provide other kinds of error message like event log or error when the user is connecting with Imap. Is there only one user encounter this problem? Thanks.Best Regards!

yes it is only happening with one user, and does not happen when they use active sync, just imap what other information should i look for from event log? any ideas at this point? cheers

Hi, The error you gave is not that useful for investigation. You can check event log and post any related error or warning message. Thanks.Best Regards!

thanks rowan. ill try to get the log and copy any errors or warnings here. do you think 'userconnectionlimit reached' is not the issue with the client connecting? i am unsure about how to interpret that. i also have a copy of the log from the imap client (thunderbird) in case it provides any clues: 3564[70e2680]: ImapThreadMainLoop entering [this=9b39000] 0[630140]: 9b39000:eximap.[CENSORED].ca:NA:SetupWithUrl: clearing IMAP_CONNECTION_IS_OPEN 3564[70e2680]: 9b39000:eximap.[CENSORED].ca:NA:ProcessCurrentURL: entering 3564[70e2680]: 9b39000:eximap.[CENSORED].ca:NA:ProcessCurrentURL:imap://[CENSORED]@eximap.[CENSORED].ca:993/verifyLogon: = currentUrl 3564[70e2680]: ReadNextLine [stream=d6818e8 nb=53 needmore=0] 3564[70e2680]: 9b39000:eximap.[CENSORED].ca:NA:CreateNewLineFromSocket: * OK The Microsoft Exchange IMAP4 service is ready. 3564[70e2680]: 9b39000:eximap.[CENSORED].ca:NA:SendData: 1 capability 3564[70e2680]: ReadNextLine [stream=d6818e8 nb=96 needmore=0] 3564[70e2680]: 9b39000:eximap.[CENSORED].ca:NA:CreateNewLineFromSocket: * CAPABILITY IMAP4 IMAP4rev1 AUTH=NTLM AUTH=GSSAPI AUTH=PLAIN CHILDREN IDLE NAMESPACE LITERAL+ 3564[70e2680]: ReadNextLine [stream=d6818e8 nb=28 needmore=0] 3564[70e2680]: 9b39000:eximap.[CENSORED].ca:NA:CreateNewLineFromSocket: 1 OK CAPABILITY completed. 3564[70e2680]: try to log in 3564[70e2680]: IMAP auth: server caps 0x1185235, pref 0x1006, failed 0x0, avail caps 0x1004 3564[70e2680]: (GSSAPI = 0x1000000, CRAM = 0x20000, NTLM = 0x100000, MSN = 0x200000, PLAIN = 0x1000, LOGIN = 0x2, old-style IMAP login = 0x4)auth external IMAP login = 0x20000000 3564[70e2680]: trying auth method 0x1000 3564[70e2680]: got new password 3564[70e2680]: IMAP: trying auth method 0x1000 3564[70e2680]: PLAIN auth 3564[70e2680]: 9b39000:eximap.[CENSORED].ca:NA:SendData: 2 authenticate plain 3564[70e2680]: ReadNextLine [stream=d6818e8 nb=3 needmore=0] 3564[70e2680]: 9b39000:eximap.[CENSORED].ca:NA:CreateNewLineFromSocket: + 3564[70e2680]: 9b39000:eximap.[CENSORED].ca:NA:SendData: Logging suppressed for this command (it probably contained authentication information) 3564[70e2680]: ReadNextLine [stream=d6818e8 nb=27 needmore=0] 3564[70e2680]: 9b39000:eximap.[CENSORED].ca:NA:CreateNewLineFromSocket: 2 NO AUTHENTICATE failed.
