Exchange - disable offline folders with non-cached mode

 ·   ·  ☕ 1 min read

Having read some useful topics on the internet, I decided to try non-cached Exchange mode in Outlook.

After disabling caching for my account, it still kept the OST file, even after forced deletion.

Then I noticed some offline folders were being kept, like Inbox and Sent Items (right click -> Synchronization tab -> Offline folder contains…).

When those were emptied, there was still something left in that OST file (<20MB). This is how you can disable offline folders altogether.

Text version (for Outlook 2010):

  1. Menu -> File -> Info -> Account Settings -> Account Settings…
  2. Select your account -> Change -> More Settings -> Navigate to Advanced tab -> Outlook Data File Settings -> Click Disable Offline Use.

Graphical version (for Outlook 2010):

outlook 2010 account settings 1

outlook 2010 account settings 2
