Microsoft Outlook is a web-based suite of webmail, contacts, tasks, and calendaring services.
Make a CSV of training sessions from an emailed calendar export.
Your weekly schedule arrives as a sortable CSV reply, with repeating meetings flagged so your team can review them before the handoff.
Send trainees current links in their session invitations.
Your guests get the current meeting invitation link when you change a scheduled video meeting, while uncertain matches come back to you for review.
