EWS - How to search for items [message] between dates ?
- by SomFred
Hi,
I am trying to search for message items between two dates from the inbox folder.
I use the following restrictionType but it throws this error:
firmt.RootFolder = null
What am I doing wrong?
There is some messages between the mentionned dates ;-)
Thanks for your suggestions.
