As an Exchange 2007 customer, it will be important to keep this in mind as you plan your upgrade cycles for both Exchange Server and the Office clients, to make sure you don’t get stuck in a bad place.In order to prevent any issues for customers using the Office 2013 apps in Office 365 Pro Plus with Exchange 2007, we temporarily disabled auto-updates for users currently connected to Exchange 2007.Some 3rd party services made changes to their APIs that resulted in their social activity being no longer available.While it will still provide views into Mail, Attachments and Calendar events from the people involved in your email, we made the decision to turn this off by default and put the focus on providing more room for the reading pane.This worked however it would have to be done every time you want to update it the address book.On exchange box ran - Update-Global Address List "Default Global Address List"received 2 warning messages "invalid and couldn't update. We upgraded from exchange 2007 to 2013 and I noticed that new employees are not populating in the global address list within our outlook 2007.I also notice that if I hit send/receive that it never finishes and gets stuck on updating address book.
Hopefully you’ve seen already seen some of what’s new in Outlook 2016 for end users – if not, here’s a quick overview.Outlook 2013 saw the introduction of the Sync Slider, which helps limit the size of OST’s by controlling how much recent mail was synced locally on the device.For Exchange accounts, this was 12 months by default, with options to go down to ‘1 month’ or up to ‘all mail’.Things that I have tried: In account settings I have unchecked "use cached exchange mode", although this did resolve the issue outlook runs slow (people complained).
Downloaded office 2016 but issue still their Deleted the Offline Address Book with C:\Users\username\App Data\Local\Microsoft\Outlook and reopened outlook.
