azure ad connect over 448 character limit

Question

Hello all

We stamp a lot of data in "ExtensionAttribute1" for mail enabled security groups. Any groups that has a character limit over 448 stamped on "ExtensionAttribute1" is not syncing anymore to Azure AD. The error message i am getting is below. I'm unsure what rule i need to modify and what value i need to use for the custom expression. Any help is appreciated

I'd recommend you split that data between ExtensionAttributes as there is no way around the 448 characters as seen below:

However, to make those objects sync you can include the follow in the attribute flow:

ExtensionAttribute1 <- Left([ExtensionAttribute1],448)
