I have a Domino 8.5.1 server and we sometimes access mail with our android phones (various models) using K-9 Mail. One user cannot sync any new messages and the messages he does get are not in the in-box anymore. I've tried everything I can think of including shutting down the Domino server and running nfixup with no options and using -f -j -v -l , I also compacted with the copy option and ran nupdall. No help. It's not his phone because I tried it on another different phone with an older version of K-9 mail as well as the default mail client on a Samsung Fascinate and got the exact same results. I think the inbox is corrupt, but it should fix with nfixup. Anyone have a clue why this is happening. It's like he has ghost messages in his in-box that are preventing actual messages from getting to the phone. Everything looks normal from the PC client and I even tried from a Mac client just in case something would be different in the view. One note, this Domino server has been running since 1996 and it's been upgraded through all the versions and across multiple Dell servers during that time. The user has been with the company the entire time, so his mail database has been upgraded along the same path. His current template is like everyone else. StdR85mail and his DB size is currently about 550 MB with a 650 MB limit. Any help woudl be appreciated.
