Emails containing dropbox links not being received
I send emails to clients with dropbox links pasted into the message. It's suddenly become a problem with clients not receiving the mail.

Dropbox Community ModeratorHey lenpal, would you mind showing us how a hypothetical link shows up and how it shows up after you change it, like you mentioned?
I really can't easily provide that unfortunately, but I can walk you through the process.
- You "share" a document to create a link. The link ends up having a lot of seemingly random alphanumeric characters in it, as always.
- You then paste that link into an e-mail or a calendar invite and send it.
- The e-mail or calendar invite goes nowhere -- it seems to send, but is never received by the recipient.
- THEN, you run that same link through something like tinyurl.com (which changes the link to something else).
- You paste the link from tinyurl.com into an e-mail or a calendar invite and send it.
- The recipient gets the email.
So basically, some of the links being generated by DropBox seem to be getting flagged as potentially harmful links based on the characters within the link. I've verified that it isn't happening within any filters in my client's Office365 mail system (or at least, I can't find any filter that might be doing that, and the DropBox-related messages do not show up on any alerts in the O365 admin center), and in some cases the recipient is within the organization (so it's mailing from and to the same mail server, and yet is still getting blocked by something in the middle somewhere).
I don't have an example of the affected links because my client wasn't able to e-mail them to me, as described above.
Some links generated by DropBox work, but somewhere between a third and half of the links they generate do not (to the point where they just always include using tinyurl.com as an extra step in the process of sharing links).
