Hello Rosco,
Condolences on the loss. However, as someone whom this happened to twice on a Q5 and once on a Z10, I must ask this, if you haven't done this :
How to prevent deleted Gmail messages from archiving when synced using IMAP | CrackBerry.com , the gmail-mail that gets deleted on your phone
does not go to trash, it actually gets archived in
All Mail. I found all my deleted gmail data on email, and recovered it by moving those mails to Inbox on the desktop.
I just logged into an old inactive Yahoo Account for the first time in 4 years to check the same, but it appears Yahoo has no archiving setup. What's deleted is gone, it seems, I don't know why nothing goes to trash.. My Outlook account behaves better, I recovered Outlook mails from the trash, it hadn't gotten archived.
Thankfully my EAS contacts from Outlook were untouched (which makes it exclusively a Hub issue rather than an account syncing issue). I escalated this issue with BB tech support, spoke to some lady named Kristia, who offered to speak on the phone if the issue repeated. One mention was made of Low Storage (not memory) and believe me, on the Q5 you it's all too easy to get to that state. Later, I cleared the bigger apps, the Mapping app I use recently gave an update that moved offline maps to my media card so *fingers crossed* no Storage issues. Coincidentally, the Hub issue itself hasn't repeated since November. Hope your troubles get fixed too.
Regards,
*edit* to what I read in the previous post, I could be wrong but I think it is a 10.2 issue, I could be wrong about this with respect to others, but all 3 incidences I have experienced were on 10.2. But I've got data logging on, and if it does happening, I have phone date with Kristia or whoever in Tech support. On a side note, I just thought, why is BB support not on BBM and CHannels? So cool if you could screenshare and SHOW them the issue!
