Any alternate suggestions please?

What dont you like about Dynamics?

It's important that we can access the database via an ODBC link or direct link from within Microsoft Access. Kindly suggest Open Source and Paid for options.

depends on what you want to do with it

for example sales force has contact management  https://www.salesforce.com/au/form/semfy17/sales_accounts_contacts.jsp
or you can try https://www.bitrix24.com/uses/free-online-contact-management.php


again, there are too many of them, and you just need to the one you like

Please ensure that suggestion complies with below request as cannot see this in the above as yet:
Say, storing contacts and getting access to them, I find, has been an on-going issue. I am looking for a cloud-based software with good management of contact (name, surname, contact numbers, addresses etc). It's important that we can access the database via an ODBC link or direct link from within Microsoft Access. Kindly suggest Open Source and Paid for options. It's also important that Custom contact fields  can be created. A Good To Have, would be a history of changes to the contact, eg. if address changes or phone numbers change, that the history is kept, thanks, Shaun.

Tx - this is a great answer. Cost of product is too high for us... Any lower cost or open source options please?

Tx. Please comment as per Jian An Lim

Does it allow ODBC access?
PS I'm really looking for something low cost or open source with the above requirements - and other suggestions? We don't need anything fancy - its really just to store our contacts.

Act! does allow ODBC access.
