Gmail 30GB storage limit reached but can't find cause
A friend of mine has Google Workspace basic with 30GB gmail. She's not using photos or Drive so the storage totals has all gmail around ~30GB and nothing for drive and photos. She's getting the 30GB storage limit warnings and deleting old mail isn't helping.
In outlook desktop, the PST file when exported was only 17GB.
When I did a Takeout at the start, the zip was 17GB and that unzipped to 30GB. I've archived more years and now it's down to something like 10TB. The Google export showed this as also 17GB zipped, so that's interesting. Most attachments are pdfs.
It'll take some hours to transfer the zip and open the mbox file, but after that I'm not sure how to track down the size. But it seems that the mbox is likely to be 30GB still.
My current guess is that this is label related, causing duplicates?
Prior to doing anything, Outlook showed that there was a gmail orphaned mailbox. Removing the account in Outlook and readding it didn't return. Googling, sounded like a gmail-apple issue, and I know she uses iPhone, but didn't mention anything about seeing an orphaned mailbox. But I wonder if this is something from using iPhone Mail app and gmail on iPhone app? She's away for the weekend so I can't check.
At some point, I think I might need Google customer support, but I've found them to be nearly useless in the past.
Anyone know of any good mbox utilities to figure out what is using up the space and how to get rid of it? The viewer I have now doesn't seem to show folder or label structure, just ~65k messages in a single box.
