IMAP Unable to upload message (Too many message parts.)

Hello all,

I am having a problem with eM Client throwing up this error all the time. We do have a Pro licence here at BirchBruce, although I don’t have all the details to hand, and I know that we are using mostly version 5, and we have an apple mail server. Any help would be awesome, thanks.

Also, this error is appearing across multiple machines, and I think on some of the version 6 clients we have.

Hello Gideon, does this occur, when you send a message using eM Client? What exact version number are you using on your computer, can you please check the release number in Help > About?
If this occurs while sending, can you please export the submitted messages from your sent folder to my work mail, with a reference link to this forum topic for more information?

Thank you,
