Messages reappear in inbox after they are moved or deleted

I have had an IMAP account from Zoho configured in Thunderbird for many years.

Starting several months ago (I don't remember exactly) when I move or delete messages from my inbox, they disappear for a few seconds, then reappear in my inbox. Then after a while (sometimes a few minutes, sometimes much longer) they eventually disappear again and do not come back. It's like the command is failing and retrying, or sync is overlapping with delete, or ???

This is happening on two computers, one with a brand new Thunderbird installation.

I searched and found people with similar problems and tried the solutions offered of emptying folders and compacting the inbox, trash, junk, etc. - it has not helped.

What you are describing sounds to me like the server is overloaded and not forwarding changes in a timely manner.

Many years ago I had something similar with Hotmail where they would take up to half an hour to act on mail deletions. This meant that I was getting two copies of mail in Thunderbird because the server was still reporting the deleted mail.

In this case Thunderbird updates based on your action, sends off the deletion and requests an update on the folder (it is clearly no longer in sync, you deleted something. The server sends the old information and then some time latter notifies of a change and the email disappears.

Do you have the frequency of checking mail set to less than 10-15 minutes? That is something that might underlay an issue like this.

I have the following Server Settings enabled in Thunderbird:

Check for new messages at startup Check for new messages every 5 minutes Allow immediate server notifications when new messages arrive

I don't see how this can be a problem with the server because I have this same account configured in the iOS Mail app and it does not exhibit this problem with messages reappearing.

Oh so you use the Apple resource stealer. That is probably what is the root of the issue, shame you did not mention it first. Try turning the phone off for a half an hour and see if you still have issues after apple times out after 10 minutes or so. Apple products consume 100% of the available IMAP connection and offer no way to limit that. The result is while your apple functions beautifully everything else sits around waiting for the apple product to release some resources so they can log in and do their thing.

Note that Thunderbird will also use 5 connections by default, but that can be reduced in server settings > advanced
