Outlook completely syncs from server every logon

Hi Folks,

Situation:

- Server

Windows 2008 R2 + Terminal Services
Exchange Server 2010 SP1


- Cliënt

Outlook 2010

Problem:

One user reports a problem with Outlook. Everytime he logs on to his terminal session and starts Outlook, Outlook has to download the entire mailbox from the Exchange server.

Usually only the new items are downloaded from the server. What can cause this problem to occur?

The user has an .ost file with a size of 2GB. Do TS users need an .ost file? Could this be the problem?

Hello Sven,

Yes a TS user would require a .ost file just as working locally.

It looks like the user's Outlook is not working in cached Exchange mode?

Outlook was working in cached mode. After disabling cashed mode, and removing the .ost file, everything works fine!
