A customer contacted me the other day because their Office 365 client updates were not released to clients in a timely fashion.

Their configuration was one Automatic Deployment Rule (ADR) for all client updates, with the following configuration:

  • Date Released or Revised: Last 1 day
  • Office 365 client updates enabled
  • Evaluation schedule: Every Second Tuesday at 23:55

This is a fine setup except for the following scenarios:

  • Out of band patches are not included
  • Windows Defender Definitions in SCCM will not be up to date as they are released more frequently

Software Updates released by Microsoft are generally released on Patch Tuesday, which occurs every Second Tuesday of each month at 10 AM Los Angeles time.

Living in Sweden, this should be around 7 PM.

Looking at the Windows Updates, we can see that all of them were released at 7 PM.

Office 365 client updates, however, do not follow this timing, as you can see in the below picture:

The effect of the configuration was that the latest Office 365 patches were not included when the ADR was evaluated.


There are a number of ways to handle this.

  • Increase the evaluation frequency of your Automatic Deployment Rule, if you are only using one to handle client updates.
  • Create a separate Automatic Deployment Rule for Office 365 Client Updates.
