I have a rule setup in Outlook to "redirect" certain emails to my Gmail account. When they arrive they do not go into my inbox and end up without the "Inbox" label. Is it possible to apply the "Inbox" label manually with a filter?
Yes, you go to
settings - filters and
create new filter then put your outlook address in the
from address, go to
create filter from this search and use the
apply the label selection as the rule and then
create filter and have it
apply to the # matching conversations that it found from the "search"
This will apply it to all incoming messages that meet your criteria (you can specify additional criteria like subject containing "FWD") and any already existing "conversations" that match your criteria
If by mistake your mails are not shown in inbox, just select them, and select move to inbox from options above.
