Update: Apple changed the status on iCloud Mail from “issue” to “resolved issue” on Thursday afternoon. Problems with the service persisted for about 5.5 hours before being fixed, though.
It’s not just you having problems with an Apple email account. Apple reports that iCloud Mail has been having an ‘issue’ for several hours.
The service is not completely offline, however.
A check of Apple’s official System Status page shows a yellow dot next to iCloud Mail. That means there’s a problem but the service isn’t completely broken.
The nature of the problem is unknown. But the Mac-maker warns, “this service may be slow or unavailable.” At the time of this writing, the issue had been going on for over three hours.
If you aren‘t having problems, it doesn’t mean the system is fixed; Apple says “some users are affected.” Not all.
No other Apple services are affected. Everything else has a green light.
The range of iCloud services are generally reliable but they do have occasional problems. iMessage was partially broken last Thursday, for example.
