True, I was not aware of filing trays being virtual as this has never been involved in any issues for me before. And I agree to avoid mail folder names that are the same name due to this bug.

I've gone through the manual and under filing tray manipulation, including creating, nothing is mentioned in the manual or is there any warning against using duplicate mail folder names. And yes, I have applied a workaround at this stage. It's not ideal, but it is working now, but looking a bit untidy.

If you are going to provide filing trays, there will always be the possibility of duplicate mail folder names. It appears this has been an issue since filing trays were introduced to Pegasus. I would have thought there would have been a mention in the manual or a fix applied by now.

Anyhow, luckily Google saved my day and brought me to this thread. All is good for now as I've been able to find my "missing", copy to self, emails.

Thank you all. 

Windows 7, Pmail 4.72.572. I have the options set correctly as far as I can tell.

I send an email, and it asks me if I want a copy.
I say yes, and it asks me to choose a folder.
Here begins the problem.

If I try to save it to a project related folder,
it just does nothing.  It may be a limited number of folders,

but several important project folders have left me with no record of sent emails I know this will come back to bite me.

It does not save a copy. 

But other folders can get a copy, and I just can not understand why some and not others. 

Have you checked the folders are OK?

Close Pegasus Mail. Create a backup of the directory containing your mail. Open Pegasus Mail and right-click the affected mail folders and select check consistency. If there are problems detected you may need to re-index the folder(s).

Note that re-indexing a folder (a .pmm file) checks the folder index (a .pmi with the same name as the .pmm), and will restore any deleted messages. If after deleting a message in the past you have chosen the option to 'recover deleted space', also available via the right-click menu, those deletions will not be recoverable.

For another guess it might be a folder name issue, i.e. there might be two folders with identical names.

Yes, I have had this issue in the past.

To the OP: for clarification, if you have folders off different filing trays that have the same name, messages may appear to disappear. Check all folders that have the same name.

I have the same bug as the OP on my Windows 7 and Pegasus 4.72.572.

I've done some checking and found that my copies of messages going to a selected mail folder are instead going to another mail folder which happens to have the same mail folder name but is in another filing tray and appears higher up the folder view than the mail folder I am telling Pegasus to save my copy to.

I've checked the actual file name for both identically named mail folders and they have different system file names (PMM names), as expected.

I could change the mail folder name within Pegasus slightly so that the two mail folders have different names, but this would only be a temporary fix. eg. I put a space in front of one of the mail folder's names, and now the copy to self is going to the mail folder I am selecting.

I guess this needs some coding changes, with copy to self going to the system file name, instead of the mail folder name, where duplicate mail folder names may exist.

The solution, as described above is to rename your duplicate folders. The system filename has no bearing on this, it is their names as displayed by Pegasus Mail in your folder list that matters. You could prefix the names with the name of the parent folder or an abbreviation of it, or rename them as you see fit.

That is a work around, not a solution.

Nowhere does Pegasus Mail say, that I could find, that you can't have the same mail folder name under different filing trays. If it was illegal, Pegasus should pop up a warning telling you there is already a mail folder with that name when creating a new mail folder.

I know that the system filename has no bearing on this, which is why I suggested that the code could be changed to use the system filename instead, when executing the mail folder that you've selected to store the copy.

You forget, or are not aware, that filing trays are virtual, not physical, so to Pegasus Mail, a duplicate folder name is a duplicate folder name, regardless whether it appears in the root of the folder list or in a tray.  Avoid duplicate folder names throughout the folder tree.

You are right. However, as noted this is a bug and we hope it will be remedied in the next major release. In the meantime, we also hope that you can accept that renaming the folders as Brian has explained will stop any more of your sent messages from apparently disappearing.
