Pictures/videos sent from Gallery - where do they go? [not relevant]

That's where I was expecting it. But it was not there. I will make a few more experiments to see if there is a pattern.

It worked out for me, tested using a pic and a vid respectively. My standard account is of type general email. But as I think of it, I remeber I had to reinstall the account after one of the latest updates. Maybe a clue?

Thanks for your comment. I did not have the time for experiments yet but I remembered that I emailed that video when I was connected via 3G from a moving car. It is possible that the connection was lost at just the right moment for the email to go through but not sync to Sent although I would expect that that is a function of the email server, not client.

Right, that could be the case. I have just recalled the same trouble when I used a sluggish hotel WLAN. The sent mail was not there even though I had created the mail from inside the Email app and, same as your experience, it was delivered.

Update. Had only time for a short experiment on a home network but hete goes.

Sent two emals from Gallery, one attachment each, one after another, in this order:

1. An 11 MB video
2. A 1 MB picture

While the sending was ongoing, I went off to do other things, then came back a couple minutes later to check the progress:

1. Emal #1 (with the video) was nowhere to be seen.
2. Email #2 (with the picture) was still in Outbox of the default account.

Another few minutes, another check:

1. Email #1 still nowhere to be seen.
2. Email #2 found in Sent of the default account.

Both emails were received correctly.
