What's the most trusted video conferencing software for executive assistants scheduling frequent external meetings?

If you mean “most trusted” in a business sense—reliability, security, broad adoption, and low friction for external guests—the safest default answer is usually:

Zoom

Why it’s often the top pick for executive assistants

• Very widely used externally: clients, vendors, and partners usually recognize it.
• Reliable scheduling workflow: easy to add to Outlook / Google Calendar.
• Strong admin controls and security: passcodes, waiting rooms, host controls, SSO, recording permissions.
• Low meeting friction: guests can usually join quickly without much setup.
• Good for frequent meetings: recurring links, personal meeting IDs, and templates help a lot.

Strong alternatives

Microsoft Teams

Best if your org already lives in Microsoft 365.

• Great for internal coordination
• Strong compliance and enterprise controls
• Works well for scheduled meetings in Outlook
• External guests can sometimes find it less seamless than Zoom

Google Meet

Best if your org is centered on Google Workspace.

• Very easy for external participants
• Simple scheduling from Google Calendar
• Less feature-heavy, but reliable and clean

Quick recommendation by situation

• Most universal for external exec meetings: Zoom
• Best if you use Outlook/Microsoft heavily: Teams
• Best if you use Google Workspace heavily: Google Meet

Practical advice for an EA

For frequent external meetings, the “best” choice is often the one that:

1. your executives already use,
2. is most common with your clients,
3. integrates with your calendar system,
4. has the least join friction for outsiders.
