Apple and Microsoft were working together to fix the problems, as you can read more from this MacRumors report. In another case, the Mail app had some problems after iPhone and iPad users updated to iOS 11.
By the way, Apple knows this issue as you can see from this support article. Sometimes when I try to send out an email, it just freezes on the “sending” process, I have to double-check the sent box to make sure my email reply is delivered successfully. Because I encountered a few other issues related to Mail, such as the app taking forever to receive and send out new emails. Clearing a web browsers cache can correct problems you may have using a web browser while on the CU Boulder network or using an OIT web based program.
Some say it’s related to the macOS version your Mac is running, while others argued it’s due to the Mail app itself - hinting it’s a bug that exists for more than a decade and needs to be fixed urgently. Trying to find out the reasons why, I searched around and happened to bump into a few forum discussions where other Mac users were also experiencing the same issue.Īnd to my surprise, most of us (even the tech gurus) couldn’t figure out the exact reasons.
