When you receive attachments from users, it is not mandatory that you should download the attachment to your system. You can add it to your Zoho Docs, by which it will not only be available anywhere you go, it will also be secured in your own account.
You have an option to download multiple attachments together in a zip file. If you receive a Document or Spreadsheet or a presentation, you can now view the contents in your browser window itself. You need not go in search of a compatible system for viewing attachments like ‘DOCX’ or ‘XLSX’ or ‘PPTX’ files.
Further you can preview your calendar attachments in Zoho Calendar and thus maintain your schedules and mails together.
Whenever you receive an attachment file in Zoho Mail, you can see 2 options to download, Download and Add to Docs.
