I use Thunderbird as my mail client. When I receive invitations to Teams meetings, the links to the meeting etc disappear from the visible message, in the Message Source I can still find the links etc to the meeting and have in some cases been able to join using the link, in other cases I have asked for a new link. Today when I received a Teams invitation this happened again and when i clicked the Accept button the whole e-mail content disappeared and in my Lightning calendar appeared an event but no links. Ane clew to why this happens. Erik Wallin
