Eseries / Communicators :: E6 Stopped Sync With IMAP Email Server

since Friday28th of October, in the morning I am experiencing a rather unpleasant issue: my Nokia E6 dos not connect to my company's email IMAP email accounts. I take the opportunity to report other 3 issuesI have 2 emails accounts @mycompany.com that were regularly being used. I did not update the firmware nor performed any changes on the phone, all of a sudden the E6 does not connect with the email accounts, there is no error message.I tried the following:1) Re-entered the password of the email account, I confirm this is right2) Created one of the email accounts that were on the E6 on 2 other devices (Ipad and Palm Pre), they work perfect, both on Wifi, on my operator,(Orange) and on an other phone operator (Swisscom)3) deleted one email account, from the E6. I restarted the phone (by holding the button 8 seconds) and recreated the email account, this is not possible, I get the following error message:" service temporarily unavailable. Try again later. "4) I repeated the test (point3) both on WiFi and using the 3G operator. I got the same errorOn the E6 there is also a Gmail account, which works flawlessly.Using the email is not an option for my business, so I wish that THIS TIME I will get an effective reply from NOKIA. ( NOKIA don't tell me again that I have to use OVI account or my mailprovider does not work, because as explained I tested the settings on other devices.
