OK, I decided to try removing and recreating my account in the client, to see if something would happen differently. I first exported my local e-mails, as I was warned that they would be deleted. In recreating the account, I was surprised to see that POP3 was not offered as an option, only IMAP. I was watching pretty closely. Whatever, all of you advise using IMAP, so I proceeded. The initial result was that all of my local folder e-mails magically reappeared without me having to import them, but my inbox and sent e-mails were only a subset that had been on the server. I was able to import the rest of them from my saved export. My contacts also seem to be all there without requiring an import.
So now the server contains the larger set of inbox and sent e-mails that had previously only been on my client. This is not necessarily bad, although Iâm not used to seeing them on my phone. I assume that I can no longer delete them from my phone (or from the serverâs web interface), as the sync process will then delete them from my desktop client as well. Correct? But I would like to understand the synchronization process better. The only setting that I can find in the eM Client account setup is âMessage sync time periodâ, currently set to âall timeâ. If I read the Help file correctly, changing this is more for users who want to have on their client a (recent) subset of the messages that are on the server. The opposite of what I want.
I will probably set up automatic archiving as per Grantâs suggestion, although my past experience is that moving messages to an âolder inboxâ folder means it is less likely that I will get around to acting on them.
Thanks for all your help and attention. (I still suggest that a bug caused my POP3 functionality to stop working correctly upon the upgrade to V9, even if only a few of us were affected.)
