Hi,
Please forgive me as systems administration is not my specialty, I am filling in for the IT person who is away sick.
We are currently experiencing issues after we upgraded to Exchange Online last Friday. The issues are as follows.
- Almost all computers on the network are having issues with the Email server. The emails are delayed or they are not receiving them.
- Certain computers are not able to access the internet, outlook, or even the internal network.
I am thinking that this may be a firewall issue. Am I correct to pursue this line? Are there other issues that I should be considering?
Any help will be appreciated.
Thank you,
Michael
