should be able to save email attachments to a folder called 'email attachments' as per the www Outlook.com session and functionality
It won't let me attach word docs or pdfs unless they're in onedrive, then it just posts a link to download it. very inconvenient!
outlook mobile drive
adding attachments to emails
In setting, one can't differentiate which onedrive account is attached with which outlook account in case there're more than one accounts are configured ao please provide some feature so that user can know the mapped onedrive is for which account without opening the drive. Thanks..
