Exchange to gmail mail move & copy : I get "unspecified method" error

Hello

I configured 3 mail accounts : IMAP, Exchange and Gmail .
I can copy a mail from the IMAP inbox to the Gmail inbox.
I can not copy the same mail from the IMAP inbox to the Exchange inbox.
I can not copy a mail from the Gmail inbox to the Exchange inbox.

Anything I could check ?  Thks for your advice.

Hello Frederic, what version of eM Client are you currently using on your computer, can you please check the exact release number in Help > About? If you’re seeing any errors during copying, can you please make a screenshot of the error and submit it to us here on the forum?

Or switch to the Log tab in Operations, copy the content of the log and submit it to us here on the forum.

Thank you,
