IMAP problem for "Gmail" account
Reported by J Clark | November 23rd, 2013 @ 10:54 PM
This error message has appeared twice for me today:
MailMate encountered the following error: “An EXISTS response decreased the number of messages. This should never happen.”. Mailbox: “[Gmail]/All Mail”.
I was then given the option to retry, go offline, or something else.
It appeared when I unlocked the laptop after several hours away in both cases. The last operation I did (I think) was a search over the All Messages folder, triggered by alt-cmd-F.
I'll add more info on this if it reappears.

I assume “Retry” does not fail (otherwise it could be used for additional information). It sounds like a server bug, but the only way to be sure is to get a connection log. If it happens often then you can run MailMate with the Activity Viewer (⌥⌘0) open. After the error, you can then locate the related connection and copy/paste (relevant part of) the log to this ticket.
Thanks in advance.

I am having this problem. Retry fails in my case. When I looked at the activity monitor, I got what is below. There were lots of fetch requests above this...

@Charles: Seems like it is a server bug. What server is this?
Also, try generating logs for me like this:
- Open the Activity Viewer (⌥⌘0).
- Relaunch MailMate.
- Wait until you have seen the error at least once.
- Use “Help ▸ Send Server Logs”.
Then I'll see what I can find.

This probably is server side. I left my mail client open at work (Outlook for Mac 2016), so two programs were accessing the mail at the same time. I closed it and that seems to have fixed the problem. If it re-appears, I'll post logs.
Please let me know if you want me to check whether it re-appears (by opening Outlook 2016) in order to get logs.

@Charles: In theory, it definitely shouldn't be a problem to use multiple email clients with IMAP (it was explicitly designed for this purpose), but some servers are badly implemented. If it's reproducible then I'll be willing to look into a workaround or somehow handling it better.
