Constant error about missing email

I have a constant problem with the following error:

Unable to read message headers for a message in folder INBOX with date 15/02/2018 23:29 from the IMAP server

However, no such email exists on the server. I have logged in to Webmail for that INBOX and no such email exists, anywhere. 

I have also used Thunderbird and it cannot find it and also does not stumble when connecting via IMAP.

Furthermore, this is on my own PLESK server, so I have gone into the system itself and cannot find any such message.

Mailstore appears to be archiving OK, but this constant error message is annoying.

Here are the two error lines from the debug log if that helps:

  • 16:09:46.623 [37] ERROR: Unable to read message headers for a message in folder INBOX with date 15/02/2018 23:29 from the IMAP server.
  • 16:09:46.623 [37] ERROR: UID: FfdCPIAAFkF

Dear Graham,

can you provide some more information on your personal setup?
I see you use PLESK. Is this operating on a NAS?
Do you have any folders and files belonging to MailStore Home mapped to your NAS?
If so, please take a look at the following article, which is for MailStore Server, but also applies to Home setups:
https://help.mailstore.com/en/server/index.php?title=Using_Network_Attached_Storage_(NAS)

MailStore builds a cache when archiving a mailbox over imap. Maybe this cache is locked, readonly or otherwise defective.
It can be found in your home folder (e.g. C:\users\YOURNAME\) in the hidden subfolder \AppData\Local\MailStore Home\Cache\
Do you see a file named "MailboxCache.fdb"?
If so, can you close MailStore Home and then delete that file, or is it locked/still in use?
If you can manage to delete this file, MailStore Home will create a new one with the next archiving process.
Please watch the results then.

Also, if you are still receiving this error, a virus scanner might be watching and influencing the access to this file.
Just for testing purposes, you might disable your antivirus solution to check if archiving then finishes without errors.

T hanks for the info. I deleted the MailboxCache.fdb file and that solved the problem.
