If you need to collaborate with someone on your presentation in your old program or format, such as PowerPoint or PDF, you can email it as an attachment.
- Click File > Email as attachment.
- Select a format.
- Enter the email addresses or Groups you want to send copies to.
- (Optional) Enter a message.
- Click .
Note: This sends a copy of the presentation instead of sharing the original, so you won’t be able to use Slides’ collaboration tools.
