Several iOS device users are reporting an error message that reads, “mail service imap.gmail.com is not responding” today. They’re posting in Google’s Gmail product forum, and user SonaD, marked as a Google employee, has posted the following:
“We are aware of an issue where users are receiving an error that ‘”imap.gmail.com” is not responding’ when using IMAP on their computers, mobile devices, or tablets. We are currently working on resolving this issue.
Not all accounts are affected, so if you have multiple Gmail accounts, you may notice one works fine, while the other returns this error.
In the meantime, you can login to Gmail through your web browser (http://mail.google.com). On your phone or tablet, you can also use your device’s browser or if you’re on Android or iOS, you can download the Gmail application. I realize it’s not the way most of you want to get to your mail, but it will still allow you to get to your mail on both your computer or mobile devices.
Thank you again for your patience as we work on resolving this. We will update this post once I know all users are fixed.”
The advice above is echoed on the official Gmail support page, as well. Until it gets cleared up, use a web browser, mobile or otherwise..
