Occasionally a user may have difficulty accessing shared folders due to either changed access or processing slowing down. One of the possible causes of this issue is a cache in outlook that is too full, especially if this user has multiple shared folders. These folders get added to the cache. The process below details how to turn off downloading items from shared inboxes.
PLEASE NOTE: This process will only work if you are in Classic Outlook, if you need to apply this fix. Switch to Classic Outlook, follow these steps and then toggle back to new outlook.
How to fix (Classic):
- Open Outlook, hit “File” in the top left.
- Hit the “Account Settings” button, that will bring up a dropdown menu, just choose “Account Settings”.
- Once you do, you will get a new window that pops up called “Account Settings”
- On the “Email” tab, make sure your email account is highlighted and hit the “Change” button
- You will get a popup box saying “Exchange Account Settings” when you hit the change button. Just hit “More Settings” at the bottom.
- On the next window that pops up, go to the “Advanced” tab. Under Cache Exchange mode settings, deselect the “Download shared folders” checkbox and hit “OK”.
