I have an issue whereby Outlook for Mac is losing attachments when sending emails (typically, but not exclusively, PDF files).
If a file(s) is/are dragged and dropped into an email it is shown as attached and appears to send as normal. There are no error messages or bouncebacks, and the first we know that the email has lost the attachment is when we are advised by the recipient. Then when checking the sent folder, the email is there but again without the attachments.
Doesn't do this every-time though... sometimes the email goes with the attachments as it normally should.
I'm using version 16.62 (22052500)
Has anybody else had this issue and is there a fix? Or is it a software glitch?

Thank you MSFT. First step is getting the bug report. Looking forward to a solution and muddling through until then.
This is completely ridiculous. I have a very time-sensitive situation where I am needing to send documents and cannot.
I did just revert Outlook to Legacy, and it worked. To do this you simply click on the Help menu and select Revert to Legacy Outlook.
I am on version 16.74.2.
@microsoft Why after this long is this not being addressed? This is happening within our company as well with Mac users. Unacceptable!
I have 2 Macs on my network that are now dealing with this... hopefully there is an update soon. Sending and Receiving attachments is kind of vital to business these days.
I also have this problem on Macbook Pro 16" with touchbar. Seems Outlook doesnt send attachments but Office 365 cloud will. Uninstalled office from Mac and re-installed. Still same issue.
