Qucik Fill in E-mail Is there a size limit?

Not open for further replies.


Does anyone know if there is a size limit or a limit to the number of contacts that are kept in the Quick Fill for the address fields?

I haven't been able to find any info on this.

This would be for Outlook 2003. Also if there is a limit does anyone know if it increases or no limit with 2007 or 2010?

The autocomplete cache has a limit of 1000 names for 2003, its 2000 for 2007 and I think 2000 for 2010. The oldest unused names are removed to make room for new names.

2010 has Suggested contacts so even if names are off the autocomplete list, they are still saved in a Contacts folder. (This was done for those who never create contacts anymore and relied on the autocomplete cache.)
