Outlook for Android : attachments not synced
Hello,
on my Android Outlook app, some mails don't sync attachment. Not all. I sync mails as IMAP.
Actually, these mails have attachments in my inbox webmail (it's a mail account with my personal web hosting OVH).
On my PC with thunderbird, these attachments are correctly synced.
I flushed Outlook app cache in Android settings, without success.
Is there a way to resync mail without need to resinstall app ?
Don't say me it's yet another Outlook bug
Thanks.

Removing the email address and re-adding it may or may not help.
The email is setup as IMAP so it should only take a minute.
You could try to Reset Account:
In the Outlook app, go to Settings > Account > Reset Account.
Other than that, here are some generic mentions
Verify Sync Settings:
In the Outlook app, go to Settings > Accounts > select your account.
Ensure "Sync Email," "Sync Calendar," and "Sync Contacts" are enabled.
If using Exchange ActiveSync, ensure the correct account type is selected for full syncing capabilities.
Check Permissions:
In your Android device's settings, go to Apps > Outlook > Permissions.
Ensure Calendar and Contacts permissions are enabled.
Clear Cache and Data: - You said you tried this.
Go to Android Settings > Apps > Outlook > Storage.
Try "Clear Cache" first, and if needed, "Clear Data" (note: clearing data may require re-signing in).

It partially helped me. More attachments sync well now, but not all.
I will try your other suggestions. Thank you.
Tairiku, no restrictions with mobile data in my phone network settings.
