For example, one scenario is when two different third-party vendors update the same item, independent of each other.The user will get an error with the conflict information in the status bar.And somehow, it had updated up to 15K and now nothing happens. It appears like what @RDrast has already pointed out.To be exact, I have created a new profile and kept it to download but still the problem persists. I can assure there's no issue as other users are able to communicate without any issues. If you feel the issue is not resolving itself I would recommend checking out the Outlook Support and Recovery Assistant Here: https://configure.office.com/sara/Setup Consider changing how much email you are downloading as well to keep offline.If you don't choose an option on that dialog box, Outlook won't let you do anything else. Pressing Alt Tab will help you switch from window to window and help you see what dialog boxes might be stopping Outlook from responding.If you can't find a dialog box open, move on to the next step.Start low - and you can increase it as you validate it if you need too.
Give Outlook a few minutes to finish the process and it should start to work again.
We have the following setup: Big Hyper-V machine hosting the servers as VM's VM for CAS: WEB. XXX.local Servers are running Server 2008 R2 with Exchange 2010 SP1 Clients are all running Windows 7 Pro x64 with Outlook 2010 x64 The problem we're having is that nobody is able to see any emails received today (16th of October), but they are able to send externally.
When I reply back to the email received externally, I don't get an NDR, yet the user cannot see my email.
The content and emails in the mailboxes are not refreshed, i.e.
only the old emails are shown, and new emails are not downloaded to Outlook, even though the status bar stated that the folder is updated.
