Is there a limit on the attachment to our emails? The only thing I could find in the manual was:

"The size limit for an individual email message is 100MB."

In my groups, people are bouncing, and it says that the attachment exceeds the limit. Yet, the attachment, much less the whole email, is no where near 100mb. Can you clarify?

Linda -- Are the people who are bouncing on digest delivery? There was a recent change for digests (ref:?). Any attachments your members send can accumulate quite a bit over the course of 12 messages.

Even if not on digest, large attachments can quickly become problematic. Many mail providers won't accept emails over a certain size...and whether groups.io is willing to send them has little bearing on whether those messages ever make it through. And of course, group members on mobile plans aren't going to appreciate it very much if they are repeatedly put over their data limit.

If you have the need to frequently share lots of large files, upload them to cloud storage and provide links instead.?

Many email service providers limit attachment size to about 20 MB total email size. And, remember that there is about 15% size overhead for any email attachment. That is not commonly recognized but just compare total email size reported by your email client to the actual file size of the attachment; the text in an average email is negligible compared to the attachment size.

Rather than attach a file or photo to the email, you can upload that file to the groups.io Group website.

If you want to send larger attachments, there are many services that provide that for free as an upload/download. Recently I've been using the free "Firefox Send" with good results; you do not need to use Firefox as your browser to use Firefox Send.

I sent a Bounce Probe out yesterday, which it says was successful, but she still has that red B.

The successful delivery of a bounce probe does not, in and of itself, do anything to unbounce her account. I do note that although the probe was delivered it was, however, delayed. The fact that the "B" is red indicates that Groups.io has stopped sending anything to your member because of repeated bouncing previously, during which phase the B will have been in blue.

Have you looked at her bounce record from her Email Delivery History? That may give you some idea about why her Mail Provider is bouncing messages from your group. I have underlined that because it is entirely possible that her bouncing status is because of bounces from a different group's messages; it is also possible that it is for reasons wholly unconnected with Groups.io, and that Groups.io has simply got caught up in it. It would also be worthwhile getting your member to check her own bounce record; that is an Account level function and you cannot do it for her.

A further check is to find out who provides her Mail Service; some providers bounce traffic more enthusiastically than others.

Linda,

I also noticed that one person is listed as bouncing in red (the B is
in red). That's the first time I've seen that. Everyone else is in
blue. Is that significant?

Blue means that Groups.io is sending a bounce probe every few days, hoping to get the member unbounced. Red means that Groups.io has given up on the probes. In both cases ordinary group posts are no longer being sent to that address, and won't be until the member takes action to "unbounce" their account (email address). More details:
/g/GroupManagersForum/wiki/9674

We've been trying to figure out what the problem is, but I can't seem
to get any information.

You appear to be aware of the Email Delivery History tab of the member's page in the Members list. That tells you what the member's email service told Groups.io about its reasons for rejecting ("bouncing") the message. Some times the Reason text that goes with response code is clearcut; sometimes much less so.

In the less clear cases only that service can tell you what they really meant, but we can try to help you "read between the lines" of their text.
