Can't update mail from 0.0.86 to 0.1.3

Next best advice: where to begin... - how did you remove the mail accounts: just in the interfaces or also deleting databases? which version was it running when you deleted them? Did you remove the mail app first? - which update was this running at the time, have you done any updates since?

Removal mail accounts: just the interface, no databases deleted. Problems with exchange server sync started after the Ohijärvi update. This included the update of the mail app to 0.1.3.2. So when deleting the mail accounts I was running Ohijärvi en mail version 0.1.3.2. No OS updates or re-installs since then, Just the mail app as described above. Do you suggest that I remove the mail app invluding the databases. And if so may I ask that you talk me through de databse removal? Thx again

Hi VeraPfundt, just so I make sure I understand everything :) You were running 1.0.3.8 (Naamankajärvi) and your exchange sync was working, and when you upgraded to 1.0.4.20 the sync stopped working. You then removed the mail app (version 0.1.3.2) and reinstalled 0.0.86 but can no longer upgrade the app due to that store error?

I don't know what the exact solution is (yet) but I do have more questions :) hopefully we'll be able to work something out without having to reset the device (I should have said clear device rather than factory reset)

So one thing I'm curious about is that the version of the mail app you had after the Ohijärvi update, according to my Jolla the exact version I'm running jolla-email-0.1.3-10.27.5.jolla.armv7hl so I don't know where 0.1.3.2 comes from (check yourself with rpm -qa | grep jolla-email in the terminal). The reason I asked when you deleted the accounts is I am not sure that deleting accounts removes the databases and if that's the case, downgrading the mail app it may not work if the database schemas changed between versions.If you remove the 0.0.86 version, do you still have files under /home/nemo/.qmf/database (if so don't delete them yet!)

Hi Steph, thx for being back so quickly! Answer to your first paragraph: you've got that almost correct. The exchange sync works to the point that mail headers and senders are synced. However, opening a specific mail, the app continuously tries loading the content but the screen stays blank. Moreover the contacts of my exchange server account are not synced anymore (I haven't mentioned that so far as I suppose it's related to the other problem and thus solved with it). My current exact version is jolla-email-0.086-10.23.1.1.jolla.armv7hl. Can't retrieve the version I have removed. So I checked the Jolla Store. You're right it is 0.1.3 w/o the "2" I added. My mistake. Found the following database files in the directory you told me to check: qmailstore.db (2.41, MiB) qmmailstore.db-wal (886.64 KiB) and qmailstore.db-shm (32.77 KiB), all three of them created (?) and last modified today. Does that clear things up?

Another thing to check: How much free space you have? what does "btrfs filesystem show" I am doing some testing here and if I remove the two mail accounts from my Jolla (one IMAP, one GMail), the database files and email contents persist on disk.

If I then remove (via the store) jolla-email the files are still there. I'm now going to delete those directories, reboot and reinstall the mail app see if that works. qmailstore.db looks too small it seems to me (mine is 23mb).
