Sierra Keychain issues ?

Hi

A customer upgraded to OS X Sierra on his MBP and his iMac

iCloud is  configured with keychain sync

Mail accounts automatically get configured thanks to the keychain sync

Unfortunately on the iMac, Mail keeps asking for the password for one of the five email accounts; always the same

The request disappeared for a few hours and now is back

Is this a keychain corruption issue ? Yesterday, immediately following the Sierra upgrade I placed the ~/Library/keychain folder into the bin on both machines

Any ideas ?
thanks

No .. probably not Keychain corruption .. this "error" in OSX Mail is common enough and is usually caused by a simple error or delayed response from the mail servers.  Apple Mail can interpret a slow or incomplete response as an error in the password which IT IS NOT.

I've found that if you have a phone, tablet or a few PCs all checking the same Mail account the mail server itself (some mail servers) can reject some requests simply because it is overloaded or getting too many requests from the same IP address.

I'd suggest you reduce the frequency on both Macs with which they check for new emails and see if the problem goes away.
