increase transport rule number limit
Please increase transport rule number limit. Currently it is 300, however, we have more than 500 rules in on premise, we need these rules to be created in exchange online, we have already merged a lot, but still more than 300. and after migrating to Office 365, we may need to create more rules.

Please increase the limit of transport rules. Currently, we need 550 plus and in the future, we need more. There are some rules in which the recipient sends an email and the transport rule sets the prepend subject. We exceed the limit of transport rules and not found any alternate option. We almost made so many options for this but didn't get any solution. Request you please increase the limit so we could not get stuck.

Please increase the transport rule limit from 300 to 1000, we have 497 transport rules on On-Premise and we need to export and import them to Exchange Online and running into issue with limits. There are some rules which has recipient one on one redirect or forward, so we cannot combine 400 that we have and we need them on Exchange Online to do the migration successfully. Also please increase the number of recipients limit from 100 to greater value like 1000. On On-Premise the value is set to 10,000.
