Hi all, First of all let me just say I am not a computer expert. I used to keep on top of some apple updates in the past but as they made so many changes to their OS recently I lost track. All i know Mavericks screwed up mail app and gmail big time! I always had funny things happening with my mail app, like tones of duplicated messages, erasing emails just to see them immediately pop back onto the screen, and all of a sudden millions of emails from the past being downloaded... really erratic behaviour of mail. Two days ago I have lost almost ALL my messages from my gmail and @me account from the past 10 years or more and after some initial research I learned it is likely to do with the Mavericks OS - MAYBE?? I am very confused and don't really know what happened but here is the story: Setup: macbook pro 10.9.3 mail app with 2 account - gmail and @me.com under "on my mac" list on the left i have set up separate folders for filing emails by subject or by sender. i use mail on my iPhone and iPad the other day i was cleaning my inbox from old and unwanted emails, i do that from time to time, just search by subject, then select them all and hit delete. After that I am always double checking in the bin folder and will delete from there as well if everything i see is indeed what i wanted to get rid off. This is not a new thing, i do that aloft, always good. 2 days ago i do the same thing and everything disappeared from everywhere in my email app. everything!! All of a sudden i am left with something like 40 messages in my inbox. (i had years and years of mail) NO WAY i have deleted all the emails all the way back to 2007 or what ever...this would have taken me hours to do. I know i have selected some but not everything. The other wired thing is that some random messages did stay in one of the "on my mac" folder. just 4 messages, where there once used to be many. all the other folders are completely empty. nothing in archive, only some messages. my draft folder also looks wired... it shows 23 drafts with only two email just duplicated lots of time.. i never really saved these emails as drafts, these are 2 random emails.. i must add that in the last few days i have been staying at a friends house and hooked up to their wi-fi network. I have no idea if this has anything to do with this problem but I am trying to think of everything. I also changed my gmail password yesterday just incase my account has been compromised but that was after this happened so still need to recover these emails. I already followed google step-by-step instruction of how to find your emails and found nothing. its a BIG black hole... I checked IMAP is enabled in the google setting on the gmail web-site I sent a form to google to enquire about the missing emails and got an automatic message that they can not recover any messages and any further email on the same subject will not be reviewed. ("Because there's unfortunately no more we can do to try to recover these messages, we won't be able to respond to future inquiries."....) Lovely people. Now, the strangest thing is that every time i open the mail app i see under "mail activity" thousands of messages being uploaded..where the two grey bars are...but still nothing when mail finish opening up. where are these going and where are they coming from? What is going on? how do i get my emails back? literally, a big chunk of my life has just completely vanished. this is insane! Please heeeeeeeelp!!!
