To resolve my issues, I ended up doing a basic search in Google on how to resolve issues with apple mail on iPhone. After going through all the various steps including resetting my network settings, I was finally able to send photos. I believe resetting the network settings may have been the ultimate fix.
Also, as you suggested, I was able to go to my Outbox and send the unsent photos. Thank you for that suggestion, because I did not think to look under that folder.
Just to let you know...for the following steps, when I go to Account Settings or anywhere in these steps, it does not give me the option to enter my password. I'm not sure why under Mail, it does not give me an option to enter my password for either Hotmail or Gmail. Maybe it was a one-time deal when I added the accounts for the first time.
1 Re-enter your Hotmail password in iPhone Settings
- Go to Settings > Mail > Accounts
- Tap your Hotmail/Outlook account
- Tap Password (or Account Settings) and re-enter your current password, then tap Done
- Open the Mail app and try sending a test email again
Thanks so much for your assistance in this matter!
