removing an @ from a cache

when writing an email, auto completion suggests me addresses. It is a useful function.
But, in may case, the lookup list contains out of date adresses and they come on first line: if I simply validate the proposal, I sent to an old address…
Is there a way to check this list and clear if from old items?

PS: I think that old adresses where imported from Outlook configuration when migrating.

If it was imported from MS Outlook, then the addresses will be in your Local Folders Contacts. If you can’t see the Local Folders, you can enable them in Menu > Tools > Settings > General > Show Local Folders.

Otherwise, since using eM Client, the recipient history can be found in Menu > Tools > Settings > Mail > Compose > Recipients History.

Thanks for the tip.
I found in Local contacts folder a few old elements to be removed. It is better.
There is nothing about such old elements in history.
Old elements were still proposed as auto completion: there is a grey cross on the right of the proposition, to remove element from list.
