Hi
... and thanks for your responses. I'll try and provide more information in the hope it helps to resolve the issue:
1. I am using Aquamail version 1.6.0.6
2. Mail protocol for incoming mail is IMAP
3. Provider is 1 and 1 (mail host, domain and web host)
In terms of settings, I have a feeling the 'Deleting Messages' option in Account Options may have changed slightly since I set it up (I could be wrong here as I only have the current version to check).
When I checked my settings yesterday, all accounts were set to 'Move to Deleted folder first'. I have not changed this option since I originally set the phone and Aquamail up in September of last year. Since then, message deleted on the phone (using the trash can) have never previously been deleted on the server, and have therefore still arrived at my desktop client (Outlook). In the last few days, I noticed that mail I deleted on the phone was no longer arriving at my desktop client. When I tested this, sure enough if I deleted mail on the phone, it was deleted on the server.
I am now testing the 'Hide in the app, keep on the server' setting, to see if this works better. However, I don't want to just hide the emails, I want to delete them in Aquamail, but not on the server.
Has this option or it's implementation changed in a recent version? I have not changed any settings, so I can only assume that something has changed in the app.
Thanks again for your help.
Jules
