Do you wish to achieve the following functions:

When the app is offline, save the email content locally.
When the user connects to the Internet and opens the app again, the app automatically sends out the mail saved locally.

As you might expect, using savedata() and loaddata() can easily achieve this function.I've made a test for your reference:

1\Add a button:

Text

If(
 Connection.Connected,
 "Send an Email",
 "Send an Email(OffLine Mode)"
)/*When the app is in offline mode, it displays "Send an Email(OffLine Mode)"*/

OnSelect

If(
 Connection.Connected,
 Office365Outlook.SendEmailV2(
 "bof@xx.com",
 "Subject",
 "Body"
 ),/*When the device is online, send email directly*/
 Collect(
 EmailWaitingToBeSent,
 {
 To: "bof@xx.com",
 Subject: "Subject",
 Body: "Body"
 }
 );/*When the app is in offline mode, the content of the mail to be sent is stored in a collection named EmailWaitingToBeSent*/
 SaveData(
 EmailWaitingToBeSent,
 "Emails"
 )/*Save the collection EmailWaitingToBeSent to the local*/
)

2\Set the app's OnStart proeprty to :

LoadData(
 EmailWaitingToBeSent,
 "Emails"
);
If(
 Connection.Connected && CountRows(EmailWaitingToBeSent) > 0, /*When the device is online and there are records in EmailWaitingToBeSent, send an email and clear the collection EmailWaitingToBeSent*/
 ForAll(
 EmailWaitingToBeSent,
 Office365Outlook.SendEmailV2(
 To,
 Subject,
 Body
 )
 );
 Clear(EmailWaitingToBeSent);
 SaveData(
 EmailWaitingToBeSent,
 "Emails"
)
)

Note: Emails saved locally can only be sent automatically when the device is online and the app is reopened.

-------------------------------------------Optional step-----------------------------------------------------

If you want to check the connection status of the device in real time, send the mail stored locally in real time. Then you need to use a timer control.

Add a timer control:

AutoStart

true

Duration

1000/*loop in 1s*/

OnTimerEnd

If(
 Connection.Connected && CountRows(EmailWaitingToBeSent) > 0,
 ForAll(
 EmailWaitingToBeSent,
 Office365Outlook.SendEmailV2(
 To,
 Subject,
 Body
 )
 );
 Clear(EmailWaitingToBeSent);SaveData(
 EmailWaitingToBeSent,
 "Emails"
))

Repeat
