I have existing SharePoint 2007 Site hosted. As my current hosting provider is shutting down 2007 SharePoint because of its end of life.
Is there way that I can still use SharePoint 2007
I’m sure there are some providers out there willing to host it. However, you may want to start thinking about upgrading to a newer version. As I am sure you know, there is no more support for SharePoint 2007, so if you have any issues nor, or issues after your migration, you will be unable to get any Microsoft Support.
A couple questions I have is, how large is your environment? Do you have a lot of users?
Migrating your environment to another provider will likely cost some money that you may be able to put towards a newer environment, such as Office 365.
