Email and Calendar Known Behaviors and Recommendations

Search doesn't work in Outlook for Mac after MacOS upgrade

Search results in Outlook for Mac return limited or no results on Mac OS Mojave. Microsoft is aware of and investigating the issue.

Use Of Office Insider Program

In no case should anyone at the University Join the Office insider program, outside of designated individuals on designated test machines. Microsoft uses the Insider program to test out new feature releases, as well as, updated code to identify issues before production release. As we have seen in the last few releases, Insider track versions have had major issues that cause clients to cease functioning properly. Insider Track Versions of Office 2016 for Mac, or any issues as a result of running the insider track will NOT be supported by Northwestern IT.

Calendar Repair Assistant

Behavior: Calendar items appear on with a red box stating problem was detected and fixed.

calendar repair assistant. The red box is located at the bottom of a meeting message.

Resolution: The Calendar Repair Assistant automatically detects and corrects inconsistencies with single and recurring meeting items for mailboxes. As a result, recipients won't miss meeting announcements or have unreliable meeting information. The Calendar Repair Assistant uses the organizer's copy of the calendar item as a master copy for all meeting items. The assistant compares the attendee's calendar item with the organizer's calendar item for inconsistencies. The only exception to this rule is when the assistant compares the attendee's and organizer's response status. The assistant assumes that the attendee's response status is the correct one, and, if necessary, updates the organizer's tracking information.

Calendar Sharing Within Outlook 2016 for Mac

Behavior: Outlook 2016 users cannot see calendars shared with them by other users in the Collaboration Services system. 

Resolution: Outlook 2016 users must be granted "Reviewer" access to another person's calendar to be able open that calendar and view details. If a user only sets permission levels to allow free/busy or free/busy limited details, an Outlook 2016 user will not be able to see any details of the shared calendar. PC users must grant "full details" to the Outlook 2011 user. Mac users must grant the "Reviewer" role to Outlook 2016 users. Basic free/busy time viewing is only viewable via the Outlook 2016 Scheduling Assistant feature, or via OWA. (Note: Outlook 2016 users who have a "Reviewer" role may also be able to select another users name within the SEND AS / FROM drop down menu.  Unless you have explicit permissions to Create Items within the selected users mailbox, Exchange will not allow you to send on the behalf of the person).

Recurring Meeting Conflicts Between Scheduler and Attendees

Behavior: Attendees are not kept current with changes made to recurring meetings by meeting schedulers.

Resolution: Over time, recurring meeting updates and changes can be very difficult to manage. For reminders it is recommended that schedulers use appointments, not meetings, since there are no other attendees. With this in mind, Northwestern recommends that meeting schedulers follow the following length guidelines when creating recurring meetings to minimize conflicts for attendees:

Meeting Recurs           New Meeting Every          Total Meetings         
Daily 2-4 weeks 10-20
Weekly 2 months 8
Bi-Weekly 3 months 6
Monthly 6 months 6
Quarterly 1 year 4
Annually 3 years 3

Password/PIN for Mobile Devices

New security enhancements have been applied for all Northwestern Collaboration Services account holders. 

Incompatibilities with Certain Android Versions

Behavior:  Some Android users with older versions of the operating system, or users with custom ROM's have reported that ActiveSync will not configure properly.

Resolution:  Users should run the Exchange ActiveSync Analyzer and verify if they are able to connect. If they make multiple attempts to connect unsuccessfully, they can download Touchdown or Moxier Mail from the Android marketplace.  Both are paid applications, but have free 30 day trials. Android support is best effort.

Lync 2013 Update to Skype for Business Incompatible with Outlook 2010

Behavior:  Installing the April 2015 Lync 2013 update to Skype for Business causes Outlook 2010 to stop working.

Resolution:  Users that manually install the Skype for Business update patch for Lync 2013 while simultaneously using Outlook 2010 will need to uninstall Office 2010. Office 2013 should be installed to replace Office 2010, and then updated to the latest version to use Lync 2013. NUIT does not recommend using Lync 2013 with the Office 2010 version of Microsoft Outlook. If Office 2010 is required for a particular reason, reinstall the software, and then install Lync 2010 for instant messaging rather than Lync 2013.

Meetings Unexpectedly Canceled on iPad and iPhone Using iOS 6,7,8

Behavior:  In some situations, users may experience unexpectedly canceled meetings and events on Apple devices running iOS 6,7,8. This can occur when the meeting invitation includes a manager with one or more delegates and the event is initially acted upon in Microsoft Outlook by a delegate.

Resolution:  This is a known issue with Apple. Users should keep their device operating system updated with the latest release recommended for their device as a first step to try and resolve this issue.

If a user notices that the mobile version of their calendar is out of date, they should go into their mobile device Exchange account settings, turn off calendar synchronization, save the settings, and then turn calendar synchronization back on.

iOS users should also avoid synchronizing Exchange Calendar Data through iCloud, as this may cause unforeseen calendar issues.

Microsoft also has more information available regarding issues with Exchange Active Sync and third party devices:
