when inviting a Verse user via Microsoft Teams/Skype/O365 etc, Microsoft has decided to encapsulate the link to the meeting in angle brackets.
Although Notes and every mail client I've tested will tolerate this nonconformity, unfortunately Traveler/Verse does not. It simply has no link rendered.
Example:
--=_mixed 6612C8665BCE8631F9D25BA2C410138A_=

Impact: Many clients have a co-existence configuration, also given the vendor is widely in use the chance of hitting this gotcha is high.
