One of my enterprise clients has teams all over the world . Each team needs different set of Custom properties. We require more than 1000+ custom properties . Support says theres no upgrade possible wrt to number of custom properties . Have you faced similar issues ? Any workaround that you suggest ?
What are these properties like? Are they all individual for forms ie: form1-answer2, form3-answer5, etc.? In that case first thing I would do is look to consolidate fields or archive old ones that are no longer used. Also you could look to store some data in CDOs as opposed to properties.
