I looked for this over the net and on support.google.com but found nothing.
I've got a Google group and if I send a mail with a size more than 8MB I'll receive a failure message due to max size limitation. According to Google help I can change the maximum file size in group settings up to 25MB. But I couldn't find anything to help me with this for my group, also I didn't find anything in my group settings.
How can I change the maximum file size of attachments for the group?

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,
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.
