Hi everyone! We're currently using Samsung Email on our Android devices linked to an on-premise Exchange server, and we're dealing with a couple of frustrating issues. One problem is that the app sometimes behaves erratically for various employees, resulting in excessive data usage that eats up our mobile data allowance. We usually have to delete and reinstall the app to fix this. The second issue arises when sending multiple images in an email; they tend to get stuck in the outbox, causing a chain reaction where subsequent emails also won't send until we manually delete those stuck messages. Has anyone else faced similar problems and found any potential solutions? We're hesitant to switch to the Microsoft Outlook app because it sends all our data, including login details, through their cloud. By the way, we are using a Mobile Device Management (MDM) solution for our phones, if that matters.

We recently switched to O365 and didn’t have any issues with Samsung devices before that. Apple devices, though? Those were a nightmare with on-prem Exchange due to their default privacy settings messing things up.,
Talk about a frustration! Emails stuck in the outbox can drive anyone up the wall. But many apps are tricky when it comes to handling image attachments, especially on mobile.
I just went through a switch from on-prem Exchange to O365, and it’s a lot safer and easier to manage. If you haven’t checked it out recently, it might be worth a look. It handles security and audit issues much better.
Honestly, I think you should seriously consider switching to Outlook. The Samsung Mail app can cause more issues down the line, especially if you're using ActiveSync. With Outlook, it stores data in a container, so deleting a profile won’t wipe the entire device, which is a best practice. It also handles modern authentication way better. Plus, it’ll save you hassle with managing user accounts in Active Directory when offboarding.
I think the data usage and stuck images may be due to the size of the files being sent. You might want to check how big those images are. But honestly, I'd still recommend moving to Outlook; it’s the best client for Exchange, even if it’s not ideal on Android.
