mailman.VerifyPopLogin and mailman.VerifyPopConnection are OK but mailman.checkmail -1 error
It works for a while then goes error and stays error even in closing links and re opening, after long while or if new mail arrives it goes ok.
What is stopping getting email count? This is with hotmail.com checking every 30 sec to see if mail/new mail Only issue with "pop3.live.com"
Help???
You might be checking the mailbox too often, and Hotmail is temporarily blocking the connection. It's impossible to say for sure though without seeing some of your code, and without seeing the contents of the LastErrorText property. As soon as the call fails, log the LastErrorText property and post it here.
I found this at the Mozilla Thunderbird site, that may be of interest. It appears that Hotmail only allows a certain number of logins within a 15 minute period (the actual number may vary). This means that my suspicion that you may be hitting the server too often and are getting blocked sounds plausible:
Exceeded the login limit for a 15 minute period errors
If you login too often (due to checking for new mail) you may get a The STAT command did not succeed. Error getting message number and sizes. Mail server pop3.live.com responded: Exceeded the login limit for a 15 minute period. Reduce the frequency of requests to the POP3 server error message.
The login limit is enforced by the server, and doesn't appear to be documented. This problem occurs with other email clients too, but doesn't occur with any Microsoft email clients. There isn't any known workaround. Reducing how often Thunderbird checks for new mail in Tools -> Account Settings -> Server Settings -> Check for new mail every X minutes" helps
Yup, the problem is that you are checking the account too often (as described in the Mozilla article snippet I posted above). See this part of your LastErrorText:
STAT PopCmdResp: -ERR Exceeded the login limit for a 15 minute period. Reduce the frequency of requests to the POP3 server. POP3 response indicates failure. Failed to get STAT response Failed
There is nothing you can do about this other than check your mailbox less frequently until the problem goes away (try once every 1 minute, then once every 2 minutes, etc... until you stop getting locked out).
If Hotmail only offers POP3, then you are stuck with that I am afraid. You mentioned that Incredimail checks Hotmail every 5 minutes, but your app was checking every 30 seconds. That is a big difference and probably why Incredimail doesn't get temporarily banned while you app does.
As for MS smart phone apps - they must have their own proprietary method of checking mail that doesn't result in getting banned for frequent connections - notice part of the Mozilla article that I posted says:
The login limit is enforced by the server, and doesn't appear to be documented. This problem occurs with other email clients too, but doesn't occur with any Microsoft email clients. Fairly typical MS approach to cripple other peoples offerings in order to make their own look better by comparison.
It's just Hotmail's POP that fails other POP emails work fine
I'm using it to run a small app in systray to check and notify me of new email MS had killed it's Hotmail app and is now in outlook browser which I do not keep open so I want to replace the old notify capability (I could have checks via other email applications but want to build my own little app) Failed after first check today
------------ Code Snippet -------------------
mailman.MailHost = "pop3.live.com"
mailman.PopUsername = gMail01_USER
mailman.PopPassword = gMail01_PW
mailman.MailPort = 995
mailman.ConnectTimeout = 15
mailman.PopSsl = 1
gMail01_Cnt = mailman.checkmail
If gMail01_Cnt = -1 Then
MsgBox "Error checking email"
exit sub
end if
mailman.Pop3EndSession
The LastErrorText is cut off because only the MsgBox command can only display so much text. Try putting it in the clipboard instead, then paste it here:
If gMail01_Cnt = -1 Then
Clipboard.Clear
Clipboard.SetText mailman.LastErrorText
MsgBox "Error checking email"
exit sub
end if

Wonder how non MS smart phone apps can immediately BING when new message on my Hotmail account? Incredimail checks my hotmail every 5 min and never flagged issue.
is there another way to check MS Hotmail for new mail - it's not imap :( which would be nice - MS hosts my email on it's servers
Any alternative options for checking new emails arriving and/or email count
Thanks!!
Thanks for your help, most appreciated
and grumbles to Microsoft again. lol
