Cannot update M365-Mac to 16.105.1?

Anyone else having an issue with this?

Current Channel-Preview update (only 25-30MB per update) is failing with Outlook and Word (previously, PPT and XLS were fine).

​It takes forever to update ... then fails.

Note that another computer which previously (early last week?) was fine.

"Solution" is changing to beta channel (which comes with risk) to bypass and go direct to 16.106 (which updates fine/super fast; under 2 minutes).

Doesn't matter internet connection and attempted to do this over a period of 4 days - tried hotel (duh), hotspot (less duh - 250-600mbps), Starlink (400+ Mbps) and home fiber (2Gbps).

    Also having this issue. Reinstalling MS Autoupdate allowed all but Outlook and Word to complete updating.

    I ended up downloading the updaters for Outlook and Word 16.105.1 (26011816) from MS and these installed as expected.
