Missing Emails - Exchange 2013 - Outlook 2016 - iOS


I have a issue with missing emails. A user called me today saying that an email had popped up on his iPhone then in Outlook 2016 then immediately disappeared from both devices. I checked Deleted Items, Junk and even the Sync Issues folder and the email was nowhere to be found.

I logged into OWA and the email was also missing. Another email came in while I was logged into OWA and that too immediately disappeared. this does not happen to all emails and he still has a lot of email traffic with a 17GB Mailbox.

It is a small network with 25 users 1 DC and 1 Exchange server

I have repaired all the OST's associated with his account but he is now concerned he is missing a lot of emails and as always he's the MD.

I would like advice in how to proceed, all I can now think of is that there is a problem with the database but it seems a bit drastic to move all the users to a new database.

Any advice is welcome.

Hi, do you want to check if there are any rules that are moving the emails or deleting the details.

I will be checking the Outlook 2016.

Try to eliminate outlook as an issue first. Leave outlook 2016 closed and see if emails are staying in the inbox. If not check if there are any rules in OWA regarding rerouting. Check the following location in OWA Settings  Settings > Options > Organize email or  Settings: > Options > Mail > Automatic processing.

Hi, thanks for the reply.

Forgot to put in original post... there are rules, quite a few in fact but, none that reference the two effected emails. do I still need to delete all the rules to eliminate?

Try disabling the rules and see what happens. since i dont have visibility, I will suggest disable all rules and see what happens.

Dont remove them.

If it emails work, then it will be due to a wrong rules.
