email attachements

I can't attach files to my emails.

What to do?

@Weumutzef72 Which programm do you use? Which is the size of the attachment (the maximum in Webmail is 15 MB)?

if using Swisscom Webmail (bluewin):

1. What is the format of the attachment? PDF, TXT, JPG, other?

2. delete the browsing data from the browser you are using, also test with another browser

3. check that the space available in your Webmail account is sufficient

and if the account is saturated (limit reached) delete messages
