why are some emails staying in outbox?? They not being sent

[Jennie]

I've sent some emails from my outlook and they're still in my outbox. It's
only on some emails. I am able to send other emails while some are just
staying in my outbox. Any suggestions??

Couple questions for ya:

Do you have multiple email addresses configured with that profile? If so,
are you perhaps using a different account to send those particular emails? I
doubt it, but it doesn't hurt to ask

Do you receive any errors when trying to send those emails?

Are there any large attachments attached to said emails?

Lemme know!
