Outlook 2016 inbox folder not updating

However, after a while I worked out that having it configured this way lead to performance issues, and people who had over 500 folders had cases where the inbox would stop updating.Changing the tickbox setting resolved the issue, despite the secondary mailboxes before and after this showing as ‘Online’.

I didn’t dig into this any further so I can’t explain what was actually going on, but at a guess it was still doing some sort of sync or connection on each folder despite it being in Online Mode.My advice is – make sure the ‘Download shared folders’ tickbox is off rather than just checking that the folders show as being ‘Online’.Outlook shows the message “we didn’t find anything to show here.” when looking in a folder that shows unread items.The views in outlook can become unresponsive causing it to not display the emails.Calendar Sharing Within Outlook 2011 for Mac Outlook 2011/2016 users must be granted "Reviewer" access to another person's calendar to be able open that calendar and view details.

If a user sets permission levels only to allow free/busy or free/busy limited details, an Outlook 2011 user will not be able to see any details of the shared calendar.

After migrating to Outlook 2016 from 2010, I noticed this inconsistency.

If you use secondary mailboxes in Outlook, you’re probably going to want them in Online Mode rather than Cached Mode.

PC users must grant "full details" to the Outlook 2011 user.

Mac users must grant the "Reviewer" role to Outlook 2011 users.

That means that all rules created in Outlook 2011 will be applied only when Outlook 2011 is running.
