'Cannot load message' error in mail

I'm having this issue on both PC and MAc. I use mainly Opera Browser and MS Edge. Cleared Cache etc.. and tried in Incognito mode......Guess what it worked!!! Incognito and also I had to do the Two Authentication send to phone stuff... but it seems to work in Incognito screen on my PC using Opera GX.

I'm so glad to see this is a widespread issue, not just my Mac or icloud account! I've just tried using it in an Incognito window, as someone suggested, and it works a treat on my Macbook - thank you! Hopefully Apple will resolve the issue soon.

Have you tried clearing your cache/cookies?

As a workaround, sometimes if I double click the mail message to open it in a popup window I am able to see the message. The message content is usually then populated in the normal View window (but not always).

Dear Apple,

Please release a decent webmail App. The current app. is rated by myself as 3 out of a possible 10 score.

This is not acceptable for a multi billion dollar company. Stop ignoring your loyal customers now!

Same issue here, persisting for over a month. I receive this message on Firefox and Chrome on two different PCs (Windows 8 and Windows 10). This problem really doesn't happen on Vivaldi - this might be my new favorite browser.

Update: I bit the bullet today and called Apple. They tried the usual: clear cache, browser, etc. I was polite and persistent, pointing back to this forum to indicate that browsers, machines, etc. didn't seem to have anything to do with it. Thanks to all of you for posting so that the problem was clear. My advisor indicated that this will go to the engineers, so maybe it will actually get fixed. I'll update when I have any other news.

This iCloud mail problem started for me 3 or 4 weeks ago. It is bad on Safari on my macbook, but I can double click multiple times and get the content of an email but on my windows machine with Firefox I literally have to refresh the page to get 1 mouse-click of functionality. I have reported it and my account was, with my permission, put in some mode where information is available to support staff. So far...no change.

Although I DO have Outlook on my Windows machine, I access Apple mail through iCloud for Windows in my browser, not directly through Outlook.

Although some of us DO use Outlook, others apparently don't. This problem also appears through all of the different browsers and off-shoots (I use the Vivaldi form of chrome/chromium).

The major commonality so far as I can tell is that we are all trying to access Apple Mail. Some use Macs, some use Windows machines. Some use one browser, others a different one, and some have reported problems on multiple browsers on the same machine.

Its not your Dell Laptop...I'm getting the same message every time I click on an email and I use an iMac.

I am experiencing the same issue.

Mine has been going on for about two weeks. It seemed to stop over the weekend and then started doing it again on 9/7.

I have tried it on multiple browsers on a PC and a Mac and the problem persists on each.

I link to Microsoft 365 Outlook as well as viewing my Apple Mail through a browser. I rarely view it in Outlook.

My primary browser is a variant of Chrome called Vivaldi. (It is more secure AND does not give all of that information to Google.)

(I also at times use Firefox, but not enough to know if this problem is present in that browser.

I do not use Microsoft Edge.

I will not even HAVE Google Chrome on my computer. Chrome feeds too much information to Google.)

It may be that this is an issue present only on Chromium based browsers, or it may be more widespread.

I have to agree with randylus. I love apple, check out my e-mail --> tbrown93@me.com - yes I've been around BEFORE mobile me came out. Other platforms out there work so well. You've got great equipment and a great software platform, then everything gets tied together with icloud. Does great for photos, notes, etc, but e-mail has always been weak. That and family sharing, that's a bumpy ride there, my biggest problem there has been starting the journey prior to icloud and having an apple ID having previous purchases and now having an icloud account being different than that original apple ID, and they won't merge, so data and app sharing has been messy, even after succumbing to going to the help desk to get it straightened out.

ok so this is about the e-mail loading issue, mine still is not resolved with chrome, it works in the browser mentioned earlier, Vivaldi. I prefer chrome as at work we do a lot of collaboration on google and chrome works best, seems like it shouldn't make that big of difference being web based and Chrome, edge, safari, firefox, exlplorer are pretty major platforms that should be expected to work with.
