How to set Outlook 2016 for Mac to delay trying to renew a Kerberos ticket

Summary

You can set Outlook 2016 for Mac to delay trying to renew a Kerberos ticket. This will prevent Outlook from prompting for credentials during the defined period. When Outlook is set with the delay and a Kerberos ticket is renewed, the program will use the new ticket and try to connect online.

Note

The version of Outlook 2016 for Mac must be 15.35.170603 or later.

Here's how to set the delay:

  1. Select **Finder **> **Applications **> **Utilities **> Terminal.

  2. Run the following command:

    defaults write com.microsoft.Outlook WaitForKerberosIdentityTimeout <timeout>

    Note

    The <timeout> value represents the period before Outlook 2016 for Mac tries to renew a Kerberos ticket in seconds. You can set the value up to a maximum of 3,600 seconds (1 hour). But you can also set the value to 1,000,000, which represents infinity, causing Outlook to never try to renew a Kerberos ticket. See the following examples:

    • 120 = Delay of 2 minutes: defaults write com.microsoft.Outlook WaitForKerberosIdentityTimeout 120
    • 3600 = Delay of 1 hour: defaults write com.microsoft.Outlook WaitForKerberosIdentityTimeout 3600
    • 1000000 = Delaying infinity: defaults write com.microsoft.Outlook WaitForKerberosIdentityTimeout 1000000
