Recently, several different clients are telling me I've forgotten to add attachments - although I haven't! I'm attaching files (usually a PDF) that are way under the limit and hitting 'send'. Then I'm seeing that email in my sent items sometimes without the attachment – it's like it's been removed between hitting 'send' and actually leaving Outlook. Any thoughts on this? It's getting embarrassing and very annoying now! I'm running Mac OS Monterey v12 beta.
