[MlMt] Proton Email - Duplicate email and Impossible to delete

[Oli Sturm]

Hi,

I apologize if this is not useful, or too late. I use ProtonMail with the Bridge (version 3.18.0).

I haven’t noticed any “real” issues with it, though there is some strange behavior with the Trash folder: it displays around 600 messages which are not in fact in the Trash. Note: this is not a MailMate issue, it appears the same way in Firefox. I’ve been in touch with Proton about this before and they didn’t find a solution, but the problem exclusively occurs in archived mail several years ago and can be fixed by manually moving the mail out of the Trash. Anyway, this is all beside the point, just a curiosity.

Now, I normally never delete anything. But on this occasion I decided to try and I found that the context menu Delete command sends the message to ProtonMail’s Trash folder without a hitch.

Never seen any messages appearing twice. I hope you’ve figured this out already!

Cheers
Oli
