O365 outlook windowsapp search very slow RRS feed

  • Question

  • Hello,

    We are experiencing a very slow search in Outlook windowsapp. We are not using any cache.
    When we use OWA the search function goed really fast. 

    Anyone any ideas, on the reason why?

    Greetings

  • Hi Siegfried,

    Do you use Exchange Online mode? Does it happen to all users or specific user?

    Normally, this issue is more related with the connection speed and how much data has to sync. What’s the size of user mailbox and how many folders?

    Please try switch to Cached Exchange mode to see if same error occurs.

    Instead of instant search, we can click Search Tools > Advanced Find under Search tab to see if same issue occurs.

    Try repairing Office: To do this, please go to Control Panel > Programs and Features. Right click your Office suit and then choose Change. Click Repair.

    Besides, install available updates to see if there are any improvements.

    Any updates, feel free to post back.

    Regards,

    Perry

  • Thank you Perry,

    We switched to exchange (3 months sync) and the problem was solved.

    They have huge mailboxes >50GB in combination with a lousy internet connection.
