Outlook sync problems

Is this an Exchange, IMAP or POP account?

One thing I know regarding my Exchange account at work. If I am at work and both my Outlook and phone show I have received the mail, the phone will continue to show it as not read until I open the email client on the phone. Once I do that, it will contact the server and show it as read. Is this the behavior you are describing? Do you have Push on for the phone?

If it doesn't show after refreshing the phone, then something is wrong. Have you done any troubleshooting. Try a reset on the phone, hold the sleep/wake and home buttons together until you see the Apple logo and then release. If that doesn't help, you might delete the account from the phone and recreate it.

Well, I would try and delete the account from the phone and recreate it. If that does not fix it, then you might need to do a restore of the phone, first from a backup, and if necessary as a new device. Good luck.

I'm having this same problem, but for me it is doing it with my Outlook (formerly Hotmail) email account. But it seems random. Sometimes when I read emails through the email client, they clear on my phone, but other times they never clear on my phone. But if I read them first on my phone, they always clear from the email client. I've tried deleting the account and recreating it, but that doesn't seem to help. I've restored my phone recently too and the problem persists. Any other ideas on how to fix this?

I have a client with the same problem and she really wants it fixed! I manage the company's Office 365 account and their email is hosted in Exchange. She uses Outlook 2010 and an iPhone 5s. This behavior started after the most recent update to iOS on her phone. I also use Exchange, Outlook 2013 and an iPhone 5s and have never experienced this problem. Would be nice if Apple could provide some support ont his problem...its really irritating to delete message in Outlook and still have to delete again on the iPhone.

I agree something is wrong. I do not experience this problem with my Exchange account, and I've been through all of the iOS updates on my 5s. I would say it might be something else that is not allowing the account to refresh on the phone when deleting something in Outlook.

Apple does not particpate here on the forum. This is a user to user forum. If you want assistance from Apple, then you need to contact Apple care. If you want assistance here, I'll try and offer some, or if I cannot answer it, then others may come in to help as well.

If this person deletes something on the phone, does it update in Outlook on the computer? You say you manage it, does that mean that you work in IT? Is there a problem with any other sync with the phone, such as calendar?

Yes - I am their IT provider and moved their Exchange solution to the cloud last year using Office 365. I support 8 other companies the same way, and this is the first user who has reported this anomoly with her iPhone.

The problem is deleting anything from outlook on any computer (calendar, emails and contacts) - the deletions do NOT sync to the iPhone. The problem is only with deleted items, everything else syncs as it should. When my user deletes from the phone, it syncs fine in Outlook on her computer.

We've tried all the recommended support options, including rebuilding the mail account on the iPhone and in Outlook, clearing out her deleted items folder and compacting the size of her mailbox.

Does it not remove from the original location on the phone, or does it just not show up in the deleted folder of the phone? I am trying to figure out why only that folder seems to only work one way.

No. For example, an email deleted from the Inbox on the computer moves to deleted items in Outook on the computer, but does not move to deleted items on the iphone. She is having to double-delete every message because she works mostly on her laptop when managing email.

If you look in the Exchange logs on the server, do you see any issues with the iPhone syncing with the server? Are there any crash logs?
