2. Known issues during coexistence

The following problems will exist to a greater or lesser extent during the coexistence period. Note that, on the whole, users will notice the coexistence effect only until their mailbox is upgraded to Exchange 2010. Coexistence began on 14 February 2012.

Most people should be aware of the following issues:
  • When using Outlook Web App (OWA), you may be redirected to a URL which reads https://legacy.nexus.ox.ac.uk/owa. This is normal.
  • If your 'bookmark' or 'favourite' to Nexus/OWA looks anything like https://nexus.ox.ac.uk/CookieAuth.dll?GetLogon?curl=Z2Fowa&reason=0&formdir=2, this will cause double-authentication with many browsers. Please change this as soon as you can to https://owa.nexus.ox.ac.uk.

The intended audience for the following notes on this page is IT Support Staff and users of email clients who are confident in making changes to the set up of their software.

Table 1. Coexistence problems and their suggested work-arounds.
ProblemMitigation / work around
OWA has difficulties opening calendars cross platform (i.e. when one user/mailbox is on Exchange 2010 and the other is on Exchange 2007). Migrations have been scheduled Unit by Unit in order to avoid the occurrence of this problem. In OWA/Exchange 2010, the work around is to delete the entry/short-cut to the Calendar and add it again.
Outlook 2011 (for Mac) cannot open delegated calendars, inbox or full mailboxes cross platform. Could add a delegated mailbox as a separate account if you know the password.
Entourage 2008 EWS cannot open delegated calendars, inbox or full mailboxes cross platform. Could add a delegated mailbox as a separate account if you know the password.
Apple Mail and iCal cannot open delegated calendars cross platform. Could add a delegated calendar as a separate account if you know the password.
New Apple Mail profiles will not auto-configure correctly for iCal and Address Book. After an account has been added, the 'internal' Exchange server URL has to be altered. Ensure that both 'Internal' and 'External' server settings are updated correctly.
Davmail cannot view free/busy information across platforms. None.
