Gmail Attachment Size Limit?
For a personal Gmail account, ARADURU can apply the official-source total attachment rule to the selected file plus other attachments already in the draft. Work and school accounts are a different context because administrators set their limits.
The verified personal profile checks the combined attachment total. If this is a work or school account, switch to the Workspace profile and enter the administrator-set sending limit instead of assuming the personal Gmail rule applies.
Do not change the original file just to test a guess. Pick the closest situation and move to the matching ARADURU check.
Use the personal Gmail profile only for a personal account. For Google Workspace, use the separate verified context and the administrator-set limit.
Use the file that actually failed
Start with the same file so the result reflects the real failure, not a substitute file.
What happened when you tried to upload?
This is the only attachment
Check the selected file directly against the represented personal Gmail total.
Several attachments are already added
Include their combined size because the personal rule applies to the message attachment total.
This is a work or school account
Use the Workspace context rather than treating the personal Gmail number as universal.
A practical order before you retry
Confirm whether the sending account is personal Gmail or Google Workspace.
For personal Gmail, include the combined size of other attachments already in the draft.
For Workspace, use the administrator-set sending limit instead of guessing one.
If the represented attachment rule passes, investigate blocked types, browser, network, storage, Drive handoff, or the exact Gmail message next.
The right Gmail limit depends on the account context
A personal Gmail attachment check should not be reused as a Workspace policy claim. Match the account first, then use the exact represented rule before changing the file.
