Maximum size for attachment is 25MB. Exceeding the limit will bounce back with an error to the sender and fails to send to the group.
For attachments exceeding 25MB,
- Google Drive is the best as Google Groups and Gmail can be accessed with no additional login info which is obviously very secured.
- This can also be done with other file hosting sites like mediafire,
Dropbox, sendspace, fileserve, filesanywhere, AmazonCloudDrive,
rapidgator, zippyshare etc. But these sites may need to sign up for free to upload the files into your website account.
- In any of the sites (Google Drive or other sites), You need to upload the file and set the attachment privacy to everyone.
- Finally, share the link of the file by copy & pasting into your google groups.
If the recipients are very few and iff you have the list of emails,
then you may also send emails with attachments to each member personally (upto 25MB only).
Google Groups doesn’t support bigger sizes for attachments. To my knowledge, it allows a maximum of 25MB. I think the upload size limit it the same. If you try to upload any attachments exceeding the file size limit, they will not be posted in the group. And the error mail will be bounced back to the sender only.
