Download sizes for updates to Microsoft 365 Apps

Our goal is to provide update size information, if possible, in advance to help enterprise customers plan network bandwidth utilization.

The following tables show the approximate download size when updating from the previous release of Microsoft 365 Apps to the most current release. Actual download sizes might vary, by as much as 50 mb. If you are updating from an older release to the current release, your download size could be larger.

If you are switching to a different channel, for example from Semi-Annual Channel (Targeted) to Semi-Annual Channel, your update size could be considerably larger than what's listed in the table. It could entail a full download, which could be at least 1 GB.

Note

  • The approximate download size listed in the tables only applies to the en-us x64 version of Microsoft 365 Apps.
  • Releases from the last four months are listed.
