I did. The results remained - it didn't work for me. All devices, changing password, deleteing/re-adding acount, changing port/SSL in the mail app on my workstation, and on the laptop, even logging onto iCloud-online - no email, period. Eventually got support on the phone, answered a bunch of questions, sat on hold, got passed on to a supervisor, sat on hold for another while and they came back saying my email was in migration and I should be back online tomorrow - TOMORROW!
I promptly lost it. Completely. I "migrated" weeks ago! And if that wasn't migrating what was I doing? Well, apparently although I migrated all my devices after updating software and had done everything right, I hadn't actually been moved onto the new iCloud servers and there was a bottle neck somewhere in the process that should have finished at 3:30 am without my ever being aware. Lots of apologies were extended but nothing could be resolved sooner - frankly I almost lost it again hearing this because the business day was over and I have no idea what was missed because of this. She did however give me her number to call her in the morning if it had not resolved - by the time I finished talking to her exchanging info and cooled off (about 15 minutes later) the problem resolved itself and I am back up.
& now if you will excuse me I now have an outgoing issue to address (errr!)... I will leave with this clue however - I was told that if you are not having success with any devices but are able to at least log-on at iCloud-online, even if you still can't access email there (contacts/calendars appeared fine, just could get email to load), then its not you. You need to call support... or wait for it to clear on its own.
