How to resolve Slow Email Opening on macOS Monterey 12.4

I followed that procedure of unchecking “protect mail activity” and the mail appears to be working properly. Thank you.

Unchecking "Protect Mail Activity' and checking "Hide IP Address" in Privacy-Mail Preferences worked great for me everything is back to normal.

In my case, unchecking ‘protect mail activity’ under privacy AND ‘include related messages’ under the View tab then restarting the program resolved the problem.

Holding down the Shift Key while launching Mail helped this time... what does that mean? This is a huge problem occurring daily. It is happening on both of my iMacs... Very frustrating.

Good thought, that occurred to me earlier...just tried to explore that, and since I've not messed with Console in quite a while, I see Apple has changed the interface :-( A quick look through seemed to indicate that I had to do a "Start Streaming" which resulted in this screen shot I took, that is pretty much above my pay grade, if that keys anything for you, I'm all ears!

It's stable after syncing with servers, and launches immediately.

So, next step will be to take out those accounts in my Primary Admin User space, restart, then add back.

The shift-open only works ephemerically - I mean, it might work, but not long.

The next hour and certainly day iMac Monterey 12.4 Apple Mail is again slow to open a mail - sometimes it takes 20-30 sec.

That is not acceptable.

I just had to look for a business email. half or 1 minute waiting is absurd.

Funny that in jumping from one mail to another back and forth all at once it opens. but that is just circumstance.

But I'm not a user of Apple software to do systems techie stuff.

Hey guys and dolls, remember, this is why we settled for Apple. [annoyed smiley]

Mac (Retina 4K, 21.5-inch, 2017)

Systeemversie: macOS 12.4 (21F79)

Kernelversie: Darwin 21.5.0

Today is another day.

Started out OK. Had re-booted the computer.

Emails fast and good.

Then all at once, after having read an email (that opened fast) , jumped to the one above (that did not open)

Then back to the one that had been open --> and that also did not open.

Maybe there is a buffer of one or two emailsin the program (like a slow writing backlog????)

Anyway, need to tell this.

So frustrating waiting a minute or two minutes just to open an email. It has to be an Apple issue. Does not happen on my iPhone when emails arrive or on my wife's laptop. Just the Mac Monterey v12.4. I even reloaded the OS, ran a disk repair, deleted then added my email account with no improvement. Sometimes Apple drives my crazy like when Music app opens mysteriously on its own even when not in the startup menu.

Now it is evening. I did all kinds of things that could have gone wrong today like before. Open simple mails, complex linked mails, open them at the same time. . .

But it went well. No problems anymore.

So I think it was some bogus that disappeared (with restart??).

Now I say: case closed.

I have done that (some time ago) but the problem returned.

I had the more than a minute wait just now.

First mail normal opening, then as I jumped to the next - zombie.

I stopped Mail, reopened - the content was there immediately - clicked on: send forward.

No response. Clicked again. No response.

As I opened this page again: the to-be forwarded mail opened = after 15 secs.

Nineteenth or 21st century?

On a late '15 iMac so this is my terminal OS (wouldn't have updated except needed to purchase MSOffice). Overall a little slow but everything works except Mail. All of the problems listed here. Tried all of the fixes here through OS reinstall. Clearly something Apple should fix. Anyone got the odds on that?

Unless you're absolutely married to the Office interface you might give these two, free, open-source apps a try": LibreOffice and SoftMaker FreeOffice 2018.  Both can open, edit and save Office douments in MS Office formats or their own format. I prefer LibreOffice and have been using it exclusively since upgrading to Catalina and later OSs.
