Fewer emails in the archive than in the mailbox


I used MailStore Home portable to archive an Exchange Server mailbox.
After the archiving was finished, archived folders have fewer emails than original ones.
What could be the cause?



  • Was there any error message in the Last Execution of your archiving profile ?
  • Are there any folders excluded as you can see for example in the below screenshot ?

Thank you for your message. I have already been able to solve my question. Thanks again

I have the same problem but I see no one posted a real answer to this topic

I’m missing about 10k messages
I can see 48000 messages on inbox on webmail (IMAP) and only 40000 on archive.
there’s also a 2000 difference in sent folder.
On cPanel the size of that account is 28GB and the archive only 19GB

Is there a size limitation of MailStore Home?
See the pictures below.



I have the same issue here. Importing from Thunderbird; no filter on folders or messages or something like that.
I tracked it down to 3 e-mails not getting imported.

One Mail is pretty old. Here some details:
