iCloud MobileMe IMAP rejected password

I am having the same error on my Mac and a similar error on my iPad.

Same situation here. However, I close my Mac Mail and then it works fine - both my Macs are behaving the same way. I am thinking the iCloud server is simply swamped and this will heal itself soon.

Yeah it seems to be intermittent right now. Sometime idevices work, sometimes not.

I'm also having this problem trying to get my @me.com address set up in the Mail client (running Leopard). Hope it sorts itself out, not a huge fan of the email interface, so hopefully can get it up and running the desk top soon.

Yep, I had the same problem. However I was trying to set up iCloud as a normal user on my Mac. Try completing setup as an administrator and then re-login to your normal account. That worked for me.

The web client though....

Same issue here...seems to be intermittent.

I even deleted and rebuilt the account on one of my Macs and it is still experiencing the same behavior.

Do folks think this is an issue with the launch or something else?

I am getting the same rejected password message, but if I time things out just right, I can get an email out or in. I tried to go in and remove the p99 from the server name, but that field is not editable.

I had the exact same problem, but it's fine now. Before my old mobileme account worked as my apple id on mac's user account. After moving mobileme to icloud, I re entered the apple-id on my user account in the user prefs and the Mail error stopped.

Maybe it will work for you too.

Same problem. Seems as though it is another botched launch. I knew I shouldn't have upgraded yet...

Yep - I have the same problem. Bloody annoying! You would think Apple would have sorted a glitch like this straight away - or before the software was released.

Just when I thought my transition to iCloud had gone OK, a couple of hours later my Mail.app on my 10.7.2 was producing this, I went on via the web (iCloud.com) and can use the same password without issue. So it is clearly a back-end issue. Very annoying.

Same here, only on my MacbookPro

As far as I know I have not migrated, but I cannot get onto mobileme at all - nothing since 5am this morning, I reckon Steve is having fun on his iCloud ;-)

Same here
