Funny New error for me today.
The SharePoint list date needs to be increased by 1 year. Seems simple, right.
However last year this item was done on 29 Feb on a Leap year, and there is no 29 Feb this year, so the Workflow is failing to update the year, because the year is invalid.
The DateTime represented by the string is not supported in calendar System.Globalization.GregorianCalendar.
Do a simple replace of the Date String
replace({DataString},'-02-29','-02-28')
Microsoft is accelerating its modernization of SharePoint and Microsoft 365 by retiring legacy technologies that were once central to classic SharePoint environments. Between 2025 and 2026, multiple long-standing features will reach end of support or be fully removed from Microsoft 365 and SharePoint Online.
The most significant retirements include:
InfoPath Forms Services and the InfoPath 2013 client (end July 14 2026), ending browser-based form support.
SharePoint Add-Ins and SharePoint 2013 workflows (April 2 2026), replaced by Power Automate and SharePoint Framework (SPFx).
SharePoint Alerts (classic “Alert Me”), Secure Store Service, and Power BI list integration, all phased out by late 2025–mid 2026.
On-premises products—SharePoint Server 2016/2019, Designer 2013, and Office Online Server—will also reach end of extended support by mid-to-late 2026.
These changes reflect Microsoft’s focus on modern, cloud-based, and low-code technologies: modern pages, Power Platform tools, and SPFx-based customizations.
The next few months mark a crucial transition period for organizations still relying on legacy SharePoint features. While many classic components will continue to function temporarily, Microsoft’s roadmap makes it clear that modernization is no longer optional — it’s essential for compatibility, security, and long-term sustainability.
To prepare:
Inventory all classic pages, InfoPath forms, workflows, and add-ins.
Prioritize migrations based on confirmed end dates (especially anything ending by mid-2026).
Adopt Power Apps, Power Automate, and SPFx for modern replacements.
Communicate and train users early, so change is smoother when retirements take effect.
By planning now, organizations can ensure a controlled, strategic modernization rather than a last-minute rush as these legacy services go dark in 2026.
