sending attachments in Thunderbird android

Could you please be more specific about the issue. The more information you can provide, the better chance we have to help solve the issue for you.

I'm running TB-A v24.0 and beta 25.0b2 and haven't experienced any issues sending attachments.

• What version of the app and android are you running?
• What file type is the attachment(s)?
• What combined file size are the attachment(s)?
• How many attachments are you adding?
• Are you adding them to a new email composition or within a reply?

How are you adding the attachments. for example,

• by clicking the paperclip attachment icon in the app,
• by using the share function within a photo gallery or other app.

Are there any error messages or silent notifications displayed in Androids notification shade when you attempt to send the email?

• Do normal emails without attachments send successfully?
• Who is your email provider?

I just set up a new email address

I can send regular messages, but when I include an attachment, they do not send. 

Rebel.com is the provider

Hi Bill

Without further information from yourself, there's no way for others to narrow down possible causes, attempt to reproduce your issue, offer you targeted diagnostic steps or potential solutions.

Are you able to answer more of the questions I asked?

Are the emails that failed to send still present in the account outbox in the mobile app?
