When using eM Client v10.3.1720 under macOS 15.4.1, I’ve been noticing an error comes up when drafting an E-mail. If it syncs while I’m still composing the message, I’m often finding it comes up with the following error in the Operations window:
[Exchange Web Services] Deleting item ‘[Message title here]’ failed due to the following error: An internal server error occurred. The operation failed.
I’m fine to continue composing the message and it seems to send without problems later, so I wonder where the issue comes from. Perhaps the issue is about saving the draft? (In my case, I’ve been having a purge of thousands of messages, so it could be an Outlook issue.) Is this a known error or are there any settings I should be checking?
