Shared mailbox not showing emails properly

Hi,

 

I have a user that is experiencing problem with emails not visible in her shared mailbox that the user is assigned to. There are several "sub-folders" under INBOX and when she click on them, most of them are empty... not sure what could be wrong here...

 

When I select sub-folder, and force "Folder Update" - it will download the emails with no issues...

 

She is using "cached mode" that is set up for 5 years. Other colleagues can see it all correctly. This user has started just 4 months ago... and looks like any email that was sent to the shared mailbox before her start, is just not showing there unless she force Folder Update..

 

Any idea what could be causing this?

 

She is using Outlook 365

    For best outlook performance and recommended practice for the shared mailbox access via outlook client is to access them via Online Mode by unchecking "Download Shared Folders Option"

    In such cases normally the deletion of OST Files helps
    - Close Outlook
    - Go to %LocalAppData%\Microsoft\Outlook
    - Delete *.ost Files here
    - Restart Outlook and wait for Synchronization

     

    Or you can disable "Download shared folders" in the Advanced Settings on the Outlook Profile to work Online on the Shared Mailbox and not have the Data in the *.ost File (Outlook Cache).

    Sometimes a user has several big Shared Mailboxes attached and this increases the *.ost size so the Syncronization does not work properly.
