outlook 2016 sync issues use cached mode

Adjusted the Cache to only be for a few months instead of All.ģ. Here's all the troubleshooting steps I had/have tried:Ģ.

The move succeeded and afterward Outlook began working correctly in cached mode again, on two different computers. I was hoping the issue was a corrupt item that would get left behind. It said there was one item corrupt item found:Ī corrupted item was encountered: Folder property 'Inbox' this is what I had hoped. When none of them solved the issue I finally created a new Mailbox Database and moved his mailbox. I went through extensive different possible solutions which I'll list below. If I turned off cached mode they would show up instantly. I have a single user that had an issue about three weeks ago where he noticed new emails would show up on his iPhone but not in Outlook. Most users also use ActiveSync devices, mostly iPhone and some Android. All users have always used Outlook in Cached Exchange Mode since many years ago without experiencing this issue. There are still a handful of Windows 7 as well. All user mailboxes are connected to using either Outlook 2013 32-bit or Outlook 2016 32-bit, mostly from Windows 10 machines of various build versions. There are 54 mailboxes in the environment. This may not seem like a long time but actually is when you are on the phone with a client who is sending you multiple emails and you have these delays for each one it can seem like an eternity.I manage an on premise Exchange 2013 environment with a single server hosting all the roles and running the latest CU. So we started deploying converting some users to use cached mode but noticed that this causes a delay in receiving emails from the Exchange server, The delay can be any where from a few seconds to a minute.

Our archiving solution allows us to keep our mailbox sizes tamed. My thoughts were to force everyone one to use Outlook in cached mode, especially since most of our mailboxes are less than 10gb. Many users are experiencing performance issues such as lagging when access folders and also getting Outlook not responding errors. All are configured to connect their Outlook 2016 client using online mode. We have Exchange 2016 on premise server w/ about 150 clients.
