Perhaps not the cause, but isitdownrightnow.com is showing that both IMAP servers for ZOHO are down. If that's correct, then this isn't an AM problem and there's nothing that can be done from the AM side.
What is the specific URL that shows Zoho IMAP servers are down (and where/region)?
Also-1: The issue -- as described -- has been going for two days; not just right now. There would be a lot of internet-sphere noise/complaints if Zoho IMAP was down for two days. I don't see mass complaints (... and if anyone sees them, specifically for IMAP, please let me know).
Also-2: As mentioned above, I've tried other IMAP clients into Zoho Mail (the Android GMAIL client, for example), and they connect and download messages via IMAP without issue. So Zoho Mail IMAP is up for me.
But there is something infinitely superior to conjecture or guessing here -- Simply try it:
- AquaMail Pro + Zoho Mail via IMAP (I use AquaMail Pro and Zoho Mail Pro).
- imap.zoho.com; Port 993, SSL (strict). And any other variation they wish to try.
- Then, if that fails, try the same IMAP settings with, say, the Android GMAIL client.
I haven't heard that AquaMail has tried this (though it's still the weekend).
Finally, assuming there's no connectivity distinction between
Zoho Mail - Free and
Zoho Mail - Pro, anyone is free to try this combination with
Zoho Mail - Free and
AquaMail - Free.
I use Pro versions for both Zoho Mail and AquaMail. Perhaps it doesn't make a difference, but I want to be complete here just in case it does.
Thanks!
